The short version
- Each has a real cost: Clio priced per user per month, so cost scales directly with headcount and adds up for growing firms; 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: Clio covers Matter management, 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.
Clio
- Priced per user per month, so cost scales directly with headcount and adds up for growing firms
- Advanced features including some automation and reporting sit in higher tiers rather than the entry plan
- Aimed at small and mid-sized firms; large firms with complex matter structures often need heavier systems
- Strongest in North America, with less depth in other jurisdictions’ compliance requirements
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
Clio: What does Clio cost?
Clio sells per-user subscriptions across several tiers. Rates change and vary by region, so check the vendor’s current pricing page rather than relying on a third-party figure.
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.
Clio: Does Clio handle trust accounting?
Yes, and it is one of the main reasons firms adopt it, because client fund rules are strict and mishandling them is a regulatory matter.

It is aimed at small and mid-sized practices. Large firms with complex matter and billing structures usually evaluate heavier enterprise systems.
