Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Litera
- There is no published pricing or self-service option anywhere; every engagement starts with a sales quote, which makes early-stage budgeting difficult for a firm evaluating multiple vendors.
- The product is assembled from roughly a dozen acquisitions in two years, and modules originating from different acquired companies do not always share a consistent interface, which shows up as friction between drafting, comparison and contract AI tools.
- Reported costs at scale, $300,000-plus a year for large deployments, put it in a similar bracket to purpose-built AI vendors like Harvey, so a firm should genuinely compare the two rather than assume Litera is the cheaper, safer choice by default.
- Contract AI review functionality originates from Kira Systems, a 2021 acquisition, and firms should confirm how much that engine has been maintained and improved versus newer AI-native competitors.
- Modules may be licensed and priced separately even within one Litera contract, so a quote for "document comparison" does not necessarily include contract AI review or vice versa.
Tabs3
- The interface follows Windows desktop conventions from an earlier era, so new fee earners and staff take longer to train than they would on a browser-based competitor.
- On-premises deployment puts backup, disaster recovery, server upgrades and patching on the firm, which small practices without IT support routinely underestimate.
- It is built around hourly and flat fee billing, so a contingency practice tracking case costs and settlement disbursements will find the case financial model a poor fit.
- PracticeMaster case management is priced separately from billing, so the advertised per-user rate is not what a firm wanting matter management actually pays.
- Choosing the on-premises option no longer avoids a subscription, because it is billed per user per month like the hosted version.

Answered from the vendors’ own pages
Litera: Is Litera one product or several?
Functionally several. It combines document comparison (Workshare), contract AI (Kira Systems), deal management (Doxly) and drafting tools built or acquired separately, sold under one brand.
Tabs3: Is Tabs3 right for a personal injury firm working on contingency?
No. It is built for hourly and flat fee billing with a firm general ledger. A contingency practice needs case cost tracking and settlement disbursement handling, which is what CASEpeer and Filevine are built around.
Litera: Can I buy Kira Systems on its own?
Not as a fully independent product for law firms; Litera acquired the law firm side of Kira Systems in 2021 and it is now sold as part of the Litera portfolio.
Tabs3: Can I still buy Tabs3 as a perpetual licence?
No published perpetual price exists. The on-premises option, called OnSite Subscription, starts at 69 USD per user per month, with the hosted Tabs3 Cloud starting at 89 USD per user per month.
Litera: Is there a published price?
No. Every deployment is a custom quote; reported figures range from roughly $50,000 to over $300,000 a year depending on user count and contract volume.
Tabs3: Does it replace QuickBooks?
For most firms yes. It includes a double-entry general ledger and accounts payable, which is the usual reason firms choose it over billing-only products.
