Verdict at a glance

Recommended for

Established firms with complex billing, trust accounting, and full financials, including firms that want on-premises software.

Bottom line

Cloud starts at $89/user/mo and OnSite at $69, plus $35 or $32 for PracticeMaster. Ask for the all-in number, ask how Cloud is delivered and test it remotely, and export before termination.

A capable choice for established firms with complex billing and trust accounting, and one of the few that still runs on your own servers. Get an all-in per-user quote, test the Cloud version from the laptops and connections your people really use, and export everything before you ever leave.

Not for

Firms that want a modern browser-first interface and a broad integration marketplace.

Pricing from

Cloud from $89/user/month; OnSite from $69/user/month (tabs3.com/pricing, vendor claims checked 2026-10-15)

Pros

  • Billing, trust accounting, general ledger, and payables in one suite (tabs3.com)
  • Cloud or OnSite deployment (tabs3.com/pricing)
  • PracticeMaster add-on for matters, documents, calendars, and conflicts (tabs3.com/pricing)
  • Published starting prices; volume discounts may apply (tabs3.com/pricing)

Cons

  • Fees are non-cancellable and non-refundable (tabs3.com/terms-of-service)
  • Data may be deleted after termination, with no stated window (tabs3.com/terms-of-service)
  • Terms can change at any time, effective on posting (tabs3.com/terms-of-service)
  • Starting prices understate an all-in configuration

Quick answer

Bottom line: Tabs3 is for established firms with complex billing and trust accounting, including firms that want software on their own servers. Tabs3 lists hosted Cloud from $89 per user per month and OnSite from $69, with the PracticeMaster add-on $35 or $32 more (vendor "starting at" prices checked October 15, 2026); ask for an all-in quote. We found no published free trial, so ask for a demo and confirm with Tabs3. The traps: fees are non-cancellable and non-refundable, so leaving an annual plan early doesn't get money back, and after termination Tabs3 may delete your data with no stated window, so export first.

Tabs3 is a legal billing and accounting suite: Tabs3 Billing for time and statements, Tabs3 Financials for trust accounting, payables, and a general ledger, Tabs3Pay for payments, and Tabs3 Connect for mobile access. PracticeMaster adds matter management, document automation, calendars, and conflicts.

How much does Tabs3 cost?#

Tabs3 starting prices

DeploymentBilling and FinancialsPracticeMaster add-on
Cloud (hosted)from $89+$35
OnSite (your servers)from $69+$32
Source: tabs3.com/pricingTabs3 pricing page, vendor claims checked 2026-10-15. 'Starting at' prices per user per month; volume discounts may apply. A user is anyone who tracks time or works in the software.

What this means for you: A user is anyone who tracks time or works in the software, so count staff, not just lawyers. Starting prices are a floor. Ask for one all-in per-user quote covering the base suite, PracticeMaster, Connect, and payments.

OnSite saves about $20 per user per month, but you take on the servers, backups, and security. That's a real cost, even if it doesn't show up on the Tabs3 invoice.

What are Tabs3's contract terms?#

  • Non-refundable. All fees are non-cancellable and non-refundable; cancelling an annual plan early doesn't earn a refund.
  • Data at termination. You must stop using the service immediately, and Tabs3 may delete your data. The terms don't state a retention window.
  • Changes. Tabs3 can change its terms at any time, effective when posted.
  • Desktop and OnSite modules are also covered by a separate end-user license agreement.

How hard is Tabs3 to set up?#

Moderate to high. Accounting setup is the work: chart of accounts, opening trust balances by client, payables, and converting data from your current system. Plan the cutover at a month end and have your bookkeeper sign off on every client's opening trust balance.

What do users say about Tabs3?#

Users generally praise Tabs3's features and support, and complain about a learning curve, slow reports, and limited integrations. Some describe the interface as dated, and several say the Cloud version feels like a hosted remote desktop rather than a browser app; confirm with Tabs3 how yours would be delivered. Run a full billing cycle and a trust reconciliation in a demo environment before you commit.

Pros and cons#

Pros

  • Deep accounting: trust, general ledger, payables.
  • Cloud or OnSite.
  • PracticeMaster for matter management.
  • Published starting prices.

Cons

  • Non-refundable fees.
  • Data deletion after termination, no stated window.
  • Terms can change on posting.
  • All-in cost exceeds starting prices.

How does Tabs3 compare with CosmoLex, Rocket Matter, and Bill4Time?#

CosmoLex puts practice management and trust accounting in one cloud product with published prices. Rocket Matter, from the same parent company, is cloud-first practice management with billing. Bill4Time is low-cost billing with trust on its legal plan. Tabs3 is the pick for firms that want the deepest accounting or need software on their own servers.
