Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CosmoLex
- The built-in accounting suits a single law firm entity, so practices with multiple entities, payroll or unusual revenue recognition still need an external accountant and a second system.
- Document management is basic storage rather than versioned matter-centric DMS, so firms with heavy document workflow outgrow it and bolt on something else.
- The integration catalogue is materially smaller than Clio, so niche intake, e-discovery or automation tools often require manual export instead of a native connection.
- Ownership sits with ProfitSolv alongside Tabs3, TimeSolv and Rocket Matter, and buyers have limited visibility into which brand receives investment over a three-year contract.
- The interface and reporting feel dated next to newer competitors, and custom reporting in particular often means exporting to a spreadsheet.
Harvey
- There is no published pricing anywhere, and no self-service tier at all, so even qualifying for a quote requires an enterprise sales process most small and mid-size firms cannot justify starting.
- 25-seat minimums put it structurally out of reach for solo, boutique and most mid-size firms regardless of interest.
- Reported additional platform fees on top of the headline per-seat licence mean the effective total cost is materially higher than the quoted seat price alone suggests.
- As a well-funded, fast-growing AI vendor, its product and pricing model are still evolving quickly, which is a real risk for a firm signing a multi-year enterprise contract now.
- Being trained and marketed specifically for BigLaw workflows means smaller firms evaluating it are comparing themselves against a product that was not built or priced with them in mind.

Answered from the vendors’ own pages
CosmoLex: Do I still need QuickBooks?
No. CosmoLex carries its own general ledger and trust ledgers, which is the main reason firms choose it over Clio or MyCase.
Harvey: Can a small firm buy Harvey?
In practice, no. There is no self-service tier, and reported 25-seat minimums and six-figure contract values put it out of reach for most small and mid-size firms.
CosmoLex: Does it handle IOLTA compliance?
Yes. Trust ledgers, overdraft prevention and three-way reconciliation are in the core product rather than in a paid tier.
Harvey: How much does Harvey actually cost?
Nothing is published. Third-party reporting estimates $1,000-2,000 per seat per month and enterprise contracts from roughly $360,000 to over $1.5 million a year including platform fees.
CosmoLex: Who owns CosmoLex?
ProfitSolv, a private-equity backed group that also owns Tabs3, TimeSolv, ImagineTime and Rocket Matter.
Harvey: Does Harvey replace Westlaw or LexisNexis?
No. It is an AI research, drafting and review layer, typically deployed alongside rather than instead of a primary legal research database.
