Aderant pricing

Aderant requires a custom proposal for Expert Sierra and related products.

In plain terms

What you pay

  • Sierra combines a fixed subscription with separate migration work.
  • Implementation, training and agent entitlements need to be specified.
  • No current starting rate or standard user charge is stated.

How Aderant pricing works

Expert Sierra has a fixed subscription, with the chosen product configuration agreed in a proposal. Current starting prices, seat allowances and agent charges are not stated. Agent access depends on licensed Aderant products.

Implementation: The cost explanation separates one-time migration from the cloud subscription and identifies implementation and training as additional costs. No amounts are given.

Confidentiality and data terms: No standard HIPAA BAA tier is identified. API transmission of protected health information requires Aderant's prior written consent.

Note: Aderant describes Sierra's pricing as a single, fixed number for a three year subscription, with hosting and infrastructure maintenance included. That three year illustration is not a commitment to a universal contract term. iTimekeep is sold in a Premium plan with a free trial. AI allowances, renewals and cancellation terms require the applicable proposal.
