The short version
- Each has a real cost: Intapp the product set is modular, so the cost of a working risk and intake configuration is well above the entry module a firm first prices.; Westlaw firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- They diverge on capability: Intapp covers Conflicts and business intake, Westlaw covers Case law and statute database.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Intapp
- The product set is modular, so the cost of a working risk and intake configuration is well above the entry module a firm first prices.
- It assumes a firm large enough to have dedicated risk and compliance staff, and smaller practices have nobody to own the workflows it introduces.
- It sits alongside document management and billing rather than replacing them, adding integration work to an already complex estate.
- Pricing is not published, and the modular structure makes peer comparison harder because two firms rarely buy the same combination.
- Deployments change firm-wide processes such as matter opening, so rollout depends on partner behaviour change and commonly slips.
Westlaw
- Firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- Casetext no longer exists as an independent, cheaper self-serve product; anyone who liked its pricing and simplicity now has to buy into the Westlaw ecosystem, typically at a higher, seat-based cost.
- Multi-year contracts are structurally rewarded with the biggest discounts, which pressures firms into 2 or 3 year commitments before they know if usage will justify the tier chosen.
- Content and features vary meaningfully between Edge and Advantage, so an apparently small monthly price difference can hide the absence of Practical Law, which many firms end up needing anyway.
- Switching away from Westlaw means retraining staff on Lexis search syntax and the Key Number System has no direct Lexis equivalent, which is a genuine cost that suppresses competitive shopping at renewal.

Answered from the vendors’ own pages
Intapp: Is Intapp a practice management system?
No. It covers risk, compliance, intake and time capture. Firms run it alongside a billing and matter financial system such as Aderant or Elite 3E.
Westlaw: Can I still buy Casetext?
No. Casetext was retired on 1 April 2025. Its AI functionality continues as CoCounsel Legal, sold only as part of the Westlaw ecosystem.
Intapp: Can we check Intapp's financial position before committing?
Yes, which is unusual in this market. Intapp has been listed on Nasdaq since 2021, so revenue and retention figures appear in public filings rather than only in sales material.
Westlaw: Why does Westlaw publish some prices but not others?
Self-service online pricing exists only for solo practitioners and firms up to 10 attorneys; larger firms are routed to a sales representative with no public rate.
Intapp: What size of firm is it for?
Large firms and advisory businesses with a formal risk function. Small practices handle conflicts inside their practice management system instead.
Westlaw: What does CoCounsel Legal cost on top of Westlaw?
Reported figures put it around $639 per seat per month as an add-on, though this is not an official published rate and varies by contract.
