How Thirdfort pricing works

Figures come from the law firm plans page at thirdfort.com/pricing/law-firms and the pricing FAQ. Essentials is from £167 a month plus VAT and credits for checks, with unlimited users, the full range of ID, AML and source of funds checks, AI agents for client due diligence and UK support. Compliance adds discounted credits on bulk purchases, task approvals and review records, a firm-wide dashboard, a custom screening profile, the open API and extended payment terms, and Enterprise adds the largest credit discounts, single sign-on and unlimited training; both are priced by quote.

Firms pay a monthly platform fee covering users, updates, support, data retention and plan features, then buy credits by subscribing to estimated yearly usage at a discount or in bundles. Contracts run 12 months, credits are valid for two years, and only completed checks are charged. No price per check is published. The commercial terms come from the Terms of Use, version 4.1.1: pricing and payment terms are agreed with each client and exclude VAT, and where a firm comes through a partner, either the partner or Thirdfort supplies the pricing.

Fees can change on 30 days' notice with a chance to stop using the Services, invoices can be disputed within 30 days, and suspension follows 7 days' notice, with interest on overdue amounts at 4 percent a year above the Barclays Bank plc base rate. Clause 4 provides for a discretionary trial at discounted Trial Pricing, and clause 16.4 confirms that minimum purchase commitments exist and survive termination for convenience. The entry price is the Essentials platform fee, £167 a month before VAT and credits.
