BigHand vs Scan Logic: how they compare in 2026
Historical billing analysis and invoice execution create different starting points for these products. BigHand Impact Analytics turns timecard narratives into consistent activity data for matter pricing, staffing and client reporting. Scan Logic interprets outside counsel guidelines, routes noncompliant entries for correction and submits invoices through BillSync. The AI Legal Index identifies BigHand's activity level cost analysis as a way to connect matter scope with a pricing discussion. Scan Logic continues into payment and appeals, while APSync captures supplier expenses for accounting. The AI Legal Index identifies its combined handling of outgoing bills and incoming costs as the broader transactional scope of this comparison. Both can help a firm understand billing problems. BigHand concentrates on the economics and allocation of legal work; Scan Logic organizes the operational path by which invoices are corrected, delivered and paid.

All 15 axes, side by side
The same grid applied to every vendor in the index, graded from public sources. Hover a grade to see what the letter means on that axis.
AI Centrality
How much of the product is actually AI. Whether the machine learning is the mechanism the buyer is paying for or a feature layered onto conventional software, and whether the vendor is specific about which is which.
BigHand combines financial, document and workforce applications, with AI concentrated in particular products. Impact Analytics converts timecard narratives into structured activity data for pricing, staffing and billing analysis. Workflow Management turns Outlook messages into support tasks and routes them by skills, availability and workload. Speech recognition handles voice instructions, while Matter Pricing includes AI enabled timecard analysis alongside budgets and financial scenarios. BigHand acquired Ayora in August 2026, with the first integrated pricing capabilities expected later that year. Much of the catalog still functions through conventional dashboards, forms, accounting connections and document tools. AI extends that broader operational suite rather than constituting every product's core.
BillSync uses AI to interpret outside counsel guidelines and evaluate time narratives before billing. OCG Live organizes extracted requirements into a library that follows guideline versions and effective dates. APSync applies AI to invoice and receipt capture, including line items and the client or matter information needed for accounting. ChatSync adds natural language questions over connected financial data. These are central analytical functions within a wider operational platform. Portal delivery, approval routing, deadline reminders and ledger synchronization would retain practical value without language models, although the automatic interpretation of guideline text and financial questions would no longer serve the same role.
Citation Accuracy and Hallucination Disclosure
Whether the vendor publishes measured accuracy on citations and assertions, grounds output to primary sources, and says plainly what its system does when it does not know. Legal has a documented public record of fabricated citations reaching filed briefs, so an untested claim of accuracy is not evidence.
Impact Analytics classifies time entries within a consistent code set, with additional task detail through UTBMS+. Its results support matter cost analysis and staffing decisions rather than legal authority. The DPA describes testing sample customer timecards, reviewing coding accuracy, adjusting the system and repeating the exercise before automatic processing begins. That is a defined quality procedure, but its acceptance thresholds, test results and error distribution are not stated. Financial dashboards make transformed data available for review and export without demonstrating a source link for every classification. A separate Ayora masking accuracy claim concerns anonymization, not the correctness of BigHand's billing analysis.
ChatSync answers questions from connected time, billing, invoice and receivables information, with current operational data replacing manually assembled reports. BillSync evaluates entries against the firm's client guidelines, and APSync extracts invoice details for review before accounting approval. These source relationships establish what the applications are intended to use. However, no answer level source links, retrieval evaluation, extraction error rate or described unsupported answer response accompanies the claims of precise results. Guideline version tracking helps maintain the input requirements but does not demonstrate that every extracted directive or financial answer is correct. No primary law citation workflow is described.
Autonomy and Oversight Model
What the system decides on its own, what a lawyer must approve, and whether the vendor documents where the review point sits. A tool that drafts under review and a tool that files without one are different products and different risks.
The service notice requires human review and verification of AI output affecting customer deliverables, reporting or core services. Matter Pricing keeps final pricing decisions with people and provides scenario modeling, budget versions and live financial views for that work. Workflow Management automatically routes support tasks, while teams can redistribute work and follow its progress. PrebillManager separately lets firms require attorney or biller approval and undo edits through its history. These are practical review surfaces, although the notice does not map each AI feature to a required approval step. Stops for uncertain classifications and recovery after an incorrect automated routing decision remain unspecified.
Noncompliant BillSync entries are flagged and routed to the responsible lawyer or billing professional, who can correct them through a secure link. Experienced legal finance staff provide additional review and quality assurance before output reaches the client. APSync applies configured approval hierarchies and presents confidence indicators around coding, leaving staff to review and approve transactions before synchronization. These are concrete points where people can intervene in the financial workflow. The product does not specify a universal confidence threshold, an automatic pause rule for uncertain guideline interpretation, or a procedure for reversing an incorrect submission after approval and delivery.
Operational and Outcome Evidence
Named, dated evidence that the product works in production at real firms or legal departments. Case studies with figures and identified customers count. Unattributed testimonials and launch announcements do not.
Dickinson Wright's Impact Analytics account names COO Michael Kolb and analytics director Renee Morris, who describe gaining greater insight into staffing, time recording and pricing. Their account combines early benefits with plans for using the data, without a measured change in outcomes. Other named users include Tasktop's Amyli McDaniel, who attributes task level cost transparency to the analytics, and Kaiser Permanente's Tamara Morgan, who describes work with BigHand's team. Workflow Management separately attributes a turnaround reduction from 99 hours to 18 to Charles Russell Speechlys. Those workflow results do not isolate the contribution of the newer email routing models or Ayora integration.
A case study follows an unnamed insurance defense firm that centralized guidelines, corrected time entries before invoice delivery and consolidated payment and appeal monitoring. The July 2026 BillSync update reports processing more than one million time entries and tens of thousands of invoice submissions. The current solutions page separately claims typical reductions in payment delays and improved realization. These accounts provide more operational detail than partner logos alone, but the customer remains unidentified and the outcome calculations lack a defined population, measurement period or comparison method. The figures do not separate model performance from billing staff intervention and workflow changes.
Privilege and Confidentiality Posture
How client confidences are handled: attorney client privilege and work product treatment, segregation of one client matter from another, whether client data trains any model, and what the vendor commits to in writing rather than in marketing.
Customer Data Access terms restrict support and implementation access to its agreed purpose, require confidentiality and keep copied information separate from other records. Customers can revoke that permission, triggering cessation of access and destruction of copies within 72 hours. The service notice prohibits using customer and personal data to train external, public or third party foundation models. The DPA still permits timecard quality testing and service improvement, with ChatGPT testing requiring express customer instruction. These provisions do not establish a prohibition on every internal model adjustment. Matter level ethical walls and specific privilege or work product protections remain unexplained across the suite.
BillSync receives client billing requirements and time narratives, while APSync processes invoice details, receipts and matter associations. ChatSync can answer questions using the firm's connected financial information. The website privacy notice concerns contact information supplied through inquiries, analytics and optional marketing cookies. It does not establish confidentiality commitments for these product inputs. Attorney client privilege, work product, model training restrictions and the treatment of information by inference providers are unspecified. A secure correction link is part of the billing workflow, but its presence does not establish a contractual limit on access or reuse of the underlying client material.
UPL and Professional Responsibility Posture
Whether the vendor is clear that it supplies a tool rather than legal advice, who its audience is, and how it addresses unauthorized practice of law, competence and supervision duties, and jurisdiction limits. ABA Formal Opinion 512 is the reference point. Where the advice line is not the duty a product raises, the axis is read through the nearest professional duty it does raise: judicial conduct rules and the reviewing duty for products sold only to courts, and the duty to bill for time actually spent for products that draft time entries.
BigHand's financial tools help firms classify work, construct budgets and edit bills. Its service notice requires verification of AI output that affects deliverables, reporting or core services, and Matter Pricing leaves final decisions to people. Neither statement assigns a lawyer a specific duty to validate machine coded work, fee narratives or charges before billing a client. Cost transparency and fair budgeting appear as product benefits rather than a framework for professional competence, fee reasonableness and AI disclosure. The website's general information disclaimer concerns website content. It does not define the professional responsibilities that accompany the operational AI used in a firm's fee process.
Scan Logic addresses law firm finance departments and attorneys handling time entries, invoice corrections and appeals. Its applications assist billing operations rather than offering a consumer legal advice service. Legal finance specialists review output, and firm personnel retain approval responsibilities within the workflow. No explicit position explains the boundary between automated guideline interpretation and professional judgment, or how use supports lawyer competence and supervision duties. The website terms describe general product information and require a separate contract for an engagement. They contain no advice disclaimer, jurisdictional restriction or professional responsibility framework for the financial conclusions and compliance decisions produced.
AI Governance and Bias Disclosure
Published governance over model behavior: who owns it inside the vendor, what is tested before release, and what is disclosed about disparate output across matter types, parties, or populations.
BigHand's Artificial Intelligence Management System governs AI processing under its service notice, which requires human verification, identifies automated interactions and prohibits training external foundation models on customer data. The timecard quality procedure adds a concrete testing sequence before automatic deployment, including sample review and system adjustment. An AIMS Manual and Statement of Applicability are listed in the trust center behind an access request. Their contents and the acceptance criteria for individual models are not available in the open notice. Impact Analytics supports equitable work allocation, but no test results assess classification differences across lawyer groups or identify who approves model releases.
The service combines automated guideline analysis with review by experienced legal finance personnel. Client requirements and firm preferences constrain billing review, and accounting approval hierarchies control the movement of expenses into the ledger. Those operational safeguards do not establish a vendor AI governance program. No model release criteria, accountable AI officer, evaluation schedule or bias assessment is identified. The leadership page names executives responsible for technology, client success and finance without assigning responsibility for AI risk decisions. Potential differences across guideline language, billing narrative styles and matter types are not accompanied by test results or a described monitoring process.
AI Safety and Data Stewardship
Retention, deletion, access control, and what happens to prompts and documents after they are processed. Whether the vendor states its subprocessors and its incident practice, or leaves the buyer to assume.
The DPA sets separate retention rules for Workflow, Matter Pricing, Resource Management, analytics and Ayora, and lists processors with their activities, data access and locations. Staff access is denied by default, follows a formal request process and ends within a day of departure. Security event logs have a minimum 30 day retention period. Customer Data Access terms add a 72 hour deadline to end access and destroy copied material after revocation. A breach notification procedure is identified in both the annex and trust center, but the procedure requires access approval. Its customer notice deadline and incident handling commitments therefore remain unknown.
The website privacy notice explains how inquiry contact details are used and how optional analytics and marketing technologies operate. Its retention statement concerns information needed for sales and support. It does not define the lifecycle of guideline uploads, financial records, conversation prompts or generated answers in the applications. Product material describes secure correction links and accounting audit trails, without a complete access control policy. Deletion procedures, backup expiry, incident notification and a register of product subprocessors are unspecified. The public website terms defer a binding engagement to a separate contract, so they do not supply the missing product data obligations.
AI Liability and Recourse
What the vendor stands behind contractually when its output is wrong. Indemnities, caps, carve outs, insurance, and whether any of it is published or only reachable through a negotiated agreement.
Customer Data Access terms apply the liability limitations from the separate BigHand Agreement to implementation and support access. They also require destruction of copied confidential data after permission is revoked. The referenced agreement's financial cap, indemnity and warranty are not included in the open access terms or DPA annexes. Trust center insurance entries identify available certificates without exposing the cover amounts or claims conditions. These materials do not establish a remedy for incorrectly coded time, a mistaken price recommendation or misrouted work. Website disclaimers address the website itself, so they do not supply the missing allocation of liability for the operational products.
Website terms say product capabilities, integrations and outcomes can vary with a firm's configuration and that a separate contract creates the binding engagement. They do not allocate responsibility for an incorrect guideline interpretation, rejected invoice or erroneous accounting entry. Human review and approval are part of delivery but do not state a legal remedy for failure. No product liability cap, AI indemnity, service warranty or insurance undertaking is available with the public terms. The financial impact of an error could involve delayed payment or lost fees, yet reimbursement obligations and correction commitments remain unspecified.
Practice Systems Integration Depth
How deeply the product reaches into the systems legal work already lives in: document management such as iManage and NetDocuments, Word and Outlook, contract lifecycle management, matter management, e-billing, and court filing systems.
Workflow Management accepts Outlook email requests as structured support tasks, then distributes work according to skills, capacity and workload. Firms configure their forms and routing processes with BigHand during implementation and can change them afterward. PrebillManager carries attorney edits through billing review, with changes processed into the accounting system and a reversible edit history. Matter Pricing imports historic matter data and tracks actual costs against budgets through financial and time recording connections. Word and document management connections are included in Document Creation packages. Detailed field mappings, authentication requirements and the supported source systems for each financial connection are not specified.
APSync has direct two way connections with legal accounting platforms including Aderant, Centerbase, Elite, Juris, Orion, ProLaw, SurePoint LMS and Tabs3. It brings invoices and receipts into the workflow, associates them with client, matter and accounting codes, and applies configurable general ledger rules. Firm approval hierarchies govern release. Approved transactions then synchronize to the accounting system with supporting documentation, notes and an audit trail. Card transaction imports and statement reconciliation extend that process to expenses. The August 2026 release identifies both the information moved and the direction of the exchange, while configuration follows the firm's existing financial structure.
Deployment Model and Data Residency
Where the software runs and where the data sits. Multi tenant cloud, single tenant, private deployment, on premises, and whether region of residence is a published option or an enterprise conversation.
Installed BigHand software runs on the customer's infrastructure, where the customer controls retention and local security. Hosted services use region specific Azure or Innovate Cloud9 infrastructure, with AWS supporting Digitory analytics and backups kept in the chosen hosting region. The processor annex distinguishes hosting from support and development access, including international personnel and specified invitation only access. Azure OpenAI anonymization for AutoCoder has named regional options. Ayora separately uses AWS and a processor list that identifies Google for generative features, but lists corporate headquarters rather than all processing locations. The suite has substantial regional detail without a complete location map for every current AI feature.
Scan Logic describes its billing workflow as cloud based and provides separate application access for BillSync and APSync. Connected accounting systems supply the operational records used in billing, expense processing and ChatSync responses. The software can be introduced through individual modules alongside the firm's established finance platform. No customer selectable hosting region, data center country or distinction between storage and model processing locations is stated. Private cloud and installation on customer premises are not offered in the product description. The geographic location of the company's Seattle operations does not determine where uploaded invoices, guideline files or generated answers are processed.
Security Certifications and Trust Center
Independent attestation a buyer can pull without a sales call: SOC 2, ISO 27001, penetration test summaries, a trust center with current reports and named scope rather than a badge image.
A downloadable A-LIGN certificate identifies BigHand Limited's ISO 27001:2022 management system, certificate ISMS-BI-040925. Issued November 6, 2025, it expires November 20, 2027 and covers development, provision, support and SaaS maintenance across BigHand entities serving professional and healthcare customers. The certificate names London and Chicago locations and includes internal legal, HR, finance and IT operations. It is available directly through the trust center. The center also lists ISO 27701, SOC 2 Type 2 and penetration testing material, with some resources requiring access approval. The certificate verifies the scoped management system; it does not certify the accuracy of individual AI outputs.
The product pages describe a secure link for correcting a flagged time entry and preserve transaction context through accounting approval. Those application features do not establish an independent security examination. No named SOC report, ISO certificate, audit period or accessible trust center accompanies the current website materials. The privacy page focuses on website contact details and consent for analytics, without identifying product encryption specifications or penetration testing results. Partner relationships with accounting and legal technology businesses do not extend those organizations' attestations to Scan Logic. The scope and availability of any independently assessed security controls remain unstated.
Model Supply Chain Disclosure
Which models sit underneath, whose they are, where they run, and whether the vendor commits to telling customers when that changes. A legal buyer inherits every dependency it cannot see.
The processor annex names Azure OpenAI for removing identifiers from AutoCoder and Digitory datasets, plus OpenAI ChatGPT for testing sample timecards only on express customer instruction. Azure supplies hosted speech recognition, while AWS hosts Digitory analytics. Ayora's separate security page identifies Google for generative AI features and a self hosted small language model for masking, without naming its family. These disclosures identify several different roles, so hosting and anonymization should not be confused with the model that classifies work. The engines behind timecard coding and email routing remain unnamed. Processor update notices do not establish a commitment covering every underlying model change.
BillSync relies on an AI engine to interpret client guidelines and evaluate narrative compliance. APSync combines AI assisted invoice capture with configurable accounting rules, and ChatSync turns financial questions into responses drawn from connected data. The site explains those product functions without identifying a foundation model, model developer or inference provider. It also does not distinguish internally trained components from external services for each module. Model versions, processing countries, provider retention and customer notification of substitutions are unspecified. The use of optical character recognition for invoice capture does not establish which language model handles guideline interpretation or conversational financial answers.
Commercial Transparency
Whether a buyer can learn what this costs without entering a sales process: published rates, the unit being charged, what sits behind an enterprise tier, and what implementation adds.
Workflow Management proposals depend on the number of licenses, access to features and the firm's configuration. Its Standard, Plus and Advanced tiers distinguish basic workflow from forms, reporting, timesheets and utilization features. Speech recognition, outsourcing, the service provider gateway and SDK are optional additions. Other packages cover resourcing, document creation, metadata, matter pricing and business intelligence, with feature differences visible across tiers. No license rate, minimum purchase or renewal uplift is stated. Implementation and training are scoped through a separate consultancy proposal. The license basis makes the structure clearer than a price request alone, while actual recurring and setup costs remain quote dependent.
OCG Live has a stated charge per guideline, giving its analysis service a defined commercial unit. BillSync, APSync and ChatSync can operate separately and address different stages of billing, expense processing and financial reporting. Their subscription amounts, charging units and usage allowances are not supplied. Implementation includes configuration, data migration, integration and staff training, with no separate fee schedule. A Quick Start begins with the firm's two largest clients and their upcoming bills, but does not carry a stated trial price or duration. Discounts, minimum commitments and renewal increases remain matters for the commercial proposal.
Firm and Practice Coverage
Who the product is actually built for. AmLaw, midlaw, small firm and solo, in house departments, government and courts, and which practice areas are supported rather than merely claimed.
Law firm operations teams use BigHand for support work, resourcing, document production, financial reporting, pricing and prebill review. Impact Analytics also serves corporate legal departments analyzing outside counsel spend, with task based cost information and staffing insights. Workflow Management has users in healthcare, property and financial services as well as law, while the index profile concerns its legal workflows. Named legal users range across regional and international firms, including Dickinson Wright, Charles Russell Speechlys and Withers. The products work on the customer's operational records rather than a jurisdiction specific legal research collection. Country availability by product and minimum firm size are not fully defined.
The core audience is midsize law firms managing complex client billing requirements without a large finance implementation team. BillSync addresses firms submitting invoices to corporate clients, insurers and administrators through multiple portals. An insurance defense case study illustrates guideline compliance, appeals and delayed payment concerns. APSync supports supplier costs and client reimbursement, while ChatSync serves attorneys who need operational financial answers. The products therefore have a defined law firm finance role across matters, rather than a claim to perform every kind of legal work. Supported jurisdictions, languages and exclusions for particular practice areas are not enumerated.
The 12 legal signals, side by side
Recorded rather than graded. These are the questions a practitioner has to answer before a tool touches a client matter, and the answers are taken from public material only.
Client Data in Training
Can material a lawyer puts into this product be used to train a model?
The service notice prohibits training external, public or third party foundation models on customer and personal data. That promise does not expressly cover every internal model. DPA annexes allow timecard service improvement and quality testing, including system adjustments; ChatGPT testing requires the customer's express instruction. Neither permission alone states a right to train models. Ayora also has a foundation model training prohibition in its own policy.
The open service notice supplies the explicit restriction, while the full BigHand Agreement is not available to establish its contractual incorporation.
Scan Logic has public website terms and a privacy notice, but neither grants a product improvement license over client files or states whether those files may train models. The privacy notice concerns information voluntarily supplied for inquiries and website analytics. A separate contract governs the actual engagement. BillSync and APSync process sensitive billing and expense material, while ChatSync uses connected financial records.
No product agreement, training control or corresponding restriction on external model providers is available with those website policies.
Prompt and Output Retention
How long does the product keep what a lawyer typed, and can that be set to zero?
Workflow audio and attachments normally remain for up to 52 days after task completion; customers can extend that period by up to a year where the feature is available. Unfinished tasks can persist until completion, deletion or termination. Other product windows differ, including three months after termination for Matter Pricing and four for AutoCoder personal data. Ayora uses 30 days with backups up to 90. These are product specific controls and deadlines. No universal zero retention setting covers every AI input, generated result and service record.
Invoice history, guideline versions and accounting audit trails remain useful throughout the billing process, but their existence does not establish a retention period for AI inputs or outputs. ChatSync responses and conversations have no specified expiry or customer deletion setting. The privacy notice keeps website contact information as needed for sales and support; it does not set a period for product prompts, uploaded financial files or provider logs. Backup deletion and access after a subscription ends are also unspecified.
Ethical Walls and Matter Segregation
Does retrieval respect the firm’s ethical walls, or can the model read across them?
The service notice states that customer and personal data processed by AI is isolated. Administrators govern Workflow Hub visibility through user permissions, and Matter Pricing includes role based access. Support access is separately controlled through confidentiality terms, formal requests and limits on copied information. Those measures do not explain how an AI request is restricted to one client's matters or how a financial system's ethical walls carry into analytics.
No detailed wall inheritance or matter exclusion procedure accompanies timecard coding, email routing or the proposed Ayora pricing integration.
APSync routes expenses through the firm's approval hierarchy and associates costs with the relevant client and matter. ChatSync connects to firm financial information so attorneys can ask questions about time, billing and receivables. Those workflow descriptions do not state whether retrieval enforces each user's source permissions or maintains separate matter walls. No ethical wall mechanism, permission inheritance rule or handling of access revocation is explained. A correction link sent to a responsible attorney describes task delivery rather than the full scope of model access.
Third Party Request and Subpoena Notice
If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?
The North American privacy policy permits disclosure for legal requests, investigations, court orders and other specified business purposes. The service notice adds that requests from law enforcement and regulators are validated before personal information is disclosed. It does not commit to telling the customer beforehand or giving time to challenge a demand. No transparency report provides the history of requests received.
The support terms' confidentiality and access revocation provisions constrain ordinary service access, without adding a notice commitment when information is sought by a third party.
The website privacy notice identifies contact and analytics information and explains its use for sales, support and website operation. It contains no procedure for compulsory disclosure of customer product data. The short website terms likewise do not address subpoenas, government requests or notice to an affected firm. An engagement requires a separate contract whose provisions are not supplied. No customer notification commitment or transparency report is available for the guideline files, billing narratives and financial records handled by the applications.
Primary Law Corpus Provenance
Where does the law in this product come from, and does the vendor have the right to use it?
Impact Analytics classifies the firm's timecard narratives and transforms billing information into task and cost data. Matter Pricing uses historic matters and current financial records to construct budgets and monitor delivery. These inputs come from customer operations, rather than an identified collection of cases or statutes. UTBMS+ is a coding approach, not a primary law corpus or license. No legal publisher, corpus update schedule or rights basis is attached to the AI classifications. The models' training datasets are also distinct from the customer records they analyze.
BillSync interprets outside counsel guidelines supplied for a firm's clients, and APSync reads invoices, receipts and associated accounting information. ChatSync answers operational financial questions from connected firm data. These inputs are customer business records rather than a stated collection of case law or legislation. The product does not name a primary law corpus, its licensing basis or an update schedule.
Guideline effective dates and version changes describe the currency of client instructions, not the provenance of legal authorities used to answer research questions.
Good Law Verification
Does the product tell you when the authority it just cited has been overruled?
BigHand's financial analytics interpret work descriptions, costs and staffing information. PrebillManager supports editing bills, while Matter Pricing compares planned and actual financial performance. None of these functions supplies later history treatment for a legal authority. Document Creation's clause bank and template tools likewise do not identify a citator or an automatic legal currency assessment. Correcting a billing code or refreshing matter cost data serves a different purpose from determining whether an opinion has been overruled. No good law verification feature accompanies the described AI workflow.
OCG Live and BillSync track client guideline versions and effective dates so billing review applies the relevant directives. Payment and appeal statuses also follow changes in the billing workflow. None of those status mechanisms determines whether a judicial authority remains good law. No commercial citator, subsequent history service or independent treatment analysis is described. The product's stated task is financial compliance and processing, and the public materials do not present authority verification as a capability of its conversational or guideline analysis functions.
Refusal and Uncertainty Behavior
What does the product do when the answer is not in the corpus?
Timecard quality testing reviews sample classifications and adjusts the system before automatic processing begins. The service notice also requires human verification of AI output affecting deliverables and reporting. Neither description states how the live classifier handles an entry it cannot confidently code, or what email routing does when a request is ambiguous. No confidence value, abstention message or automatic referral rule is described for those situations.
Ayora's separate masking accuracy percentage is a security claim, without establishing uncertainty behavior for pricing recommendations or billing classifications.
APSync exposes confidence information to support review of suggested coding and associations before an expense reaches approval. The workflow includes people who can inspect and correct the transaction. This is a confidence indicator around financial processing rather than a demonstrated refusal to answer. ChatSync describes precise responses to financial questions without a specified message for missing data, unsupported calculations or an ambiguous request.
BillSync likewise routes problematic entries for correction without defining an abstention rule for an uncertain interpretation of a client guideline.
Fabricated Citation Record
Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?
No entry in the AI Hallucination Cases database names BigHand, Digitory Legal or Ayora as of October 16, 2026. Their described capabilities concern operational work such as timecard coding, price analysis and task routing. The absence of a court record about fabricated citations does not demonstrate the correctness of those outputs, and it is not a statement about every kind of dispute involving the companies. Legal authorities are not the stated output of the financial products considered here; erroneous financial classifications raise a separate accuracy question.
The current AI Hallucination Cases database maintained by Damien Charlotin contains no matching entry for Scan Logic, BillSync, APSync, OCG Live or ChatSync concerning fabricated legal citations. The company's applications primarily process financial records and client billing instructions rather than draft court submissions. That product focus does not establish that every generated answer is accurate. No court finding about fabricated citations from these products was identified as of the stated date, and the absence does not measure extraction quality or guideline interpretation.
Bar Guidance Alignment
Has the vendor engaged in public with the ethics opinions its buyers are bound by?
The service notice addresses data isolation, mandatory human verification and AI governance, while financial product descriptions emphasize cost transparency and budget control. Neither connects those practices to a named legal ethics opinion or conduct rule. There is no explanation of how a lawyer's duties change when AI reclassifies time or supports a fee estimate. BigHand's commitment to ethical and nondiscriminatory AI processing concerns its general management framework.
It does not provide a firm with guidance on professional competence, client consent or disclosure of AI assistance in billing.
Scan Logic explains billing compliance and human quality assurance without naming a bar opinion on generative AI or mapping its product controls to professional ethics guidance. Attorneys correct entries and finance specialists review output, but those activities are not accompanied by guidance on competence, informed client consent or confidentiality duties. Client outside counsel guidelines constrain invoice processing and can differ by engagement.
Compliance with those commercial directives does not establish alignment with the separate professional obligations governing a lawyer's use of AI.
Billing and Fee Posture
Does the vendor address what happens to the bill when the work takes an hour instead of six?
PrebillManager shortens billing review and keeps an edit history, while Impact Analytics transforms timecard data to support pricing and client cost transparency. Workflow Management can record effort on completed support tasks. These records are not described as distinguishing AI performed work from human work within each client's fee record. No fee guidance explains how saved time or automated classification should affect charges to clients.
Although Impact Analytics has a corporate legal use case, the broader BigHand financial suite also serves the law firm preparing and collecting the bill.
BillSync reduces time spent correcting and submitting bills, and ChatSync aims to remove manual financial reporting work for attorneys and finance staff. The buyer is the law firm issuing invoices. Although fee and payment records are central to the product, no per matter account separates AI assistance from hours actually worked on legal tasks. The company does not explain how claimed time savings affect charges to the client or how use should be disclosed. Accounting transaction history serves a different purpose from an AI work attribution record.
Outside Counsel Guideline Readiness
Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?
The DPA annex lists processors by activity, accessed data and processing location, including Azure OpenAI anonymization and expressly authorized ChatGPT testing. Ayora's linked list separately identifies Google generative features, AWS hosting and support services. The service notice adds the foundation model training restriction and required human review. A firm can use those materials to explain several parts of its information flow.
No client facing AI disclosure or consent package combines the relevant product, providers, processing geography and conditions into a complete outside counsel approval pack.
BillSync is built to apply outside counsel billing guidelines, including rate, narrative and invoice requirements. OCG Live maintains their current versions. These functions do not supply a client disclosure package for the use of Scan Logic's own AI. The site identifies no current product subprocessor register, underlying model provider list or reusable client consent statement. A firm therefore cannot derive the provider's data handling terms from the fact that its software evaluates guideline compliance. Public website policies do not fill that product disclosure gap.
Court Disclosure Support
If a judge’s standing order requires an AI disclosure, can the product produce one?
PrebillManager preserves edits and messages, and Workflow Management provides task ownership and activity trails. The service notice requires review of AI output affecting deliverables, but does not describe retaining the particular verification decision with the generated result. No export joins the model used, input sources and human approval for each passage or classification. These operational records can help reconstruct work, without constituting an AI certification for a court or regulator. The product descriptions do not supply a filing disclosure template or an equivalent client certification workflow.
APSync carries supporting invoice material, notes and a transaction audit trail into the accounting system. BillSync records payment and appeal activity, while guideline versions establish which client instructions apply. No export combines a particular generated output with its model identity, retrieved sources and a named human verifier. The workflow is directed toward finance administration rather than preparation of a court filing.
Its accounting records may support internal review, but no court disclosure certificate or equivalent AI verification package is described.
The questions both sides leave open
Derived from the records above rather than written, so it cannot favor either vendor. Take these into both conversations and ask each side the same question.

- The firm wants consistent coding across time narratives for client reporting.
- Resourcing and professional development discussions require analysis of the work allocated.
Choose Scan Logic if
- The immediate problem is moving compliant invoices through multiple client portals.
- Expense capture needs to feed approved costs and supporting records into accounting.
- Appeal deadlines and payment status need to remain connected to submitted invoices.
In summary
BigHand
Impact Analytics structures timecard data to reveal activity costs, staffing patterns and narrative quality. Its dashboards and exports support pricing, project management and discussions with clients about the composition of legal work.
Scan Logic
Scan Logic combines guideline analysis, invoice correction, portal delivery and payment monitoring. APSync processes supplier costs and reimbursements, while the company's finance professionals help configure and supervise those workflows.
Questions buyers ask
