The short version

  • Each has a real cost: 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.; DISCO per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.
  • They diverge on capability: CosmoLex covers Built-in general ledger, DISCO covers All-in per-gigabyte pricing.
  • Prices and features above were last checked on 30 August 2026.

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.

DISCO

  • Per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.
  • Hosting is cloud only in United States regions, so matters with European, United Kingdom or Australian data residency requirements are excluded outright.
  • Review analytics, scripting and the third-party application ecosystem remain deeper on Relativity, which matters for firms with established review workflows.
  • As a listed company reporting losses, it has been through leadership change including the founder departure in 2023, so multi-year roadmap commitments carry more risk than with a private vendor.
  • Complex productions and unusual data types still require professional services, so the promise of self-service holds mainly for mainstream email and document collections.

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.

DISCO: How is DISCO priced?

Per gigabyte of hosted data per month, all-in, with unlimited users. There is no published rate card, so it is quoted.

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.

DISCO: Can data be hosted outside the United States?

Coverage is centred on United States cloud regions, so confirm residency before shortlisting for European or Australian matters.

CosmoLex: Who owns CosmoLex?

ProfitSolv, a private-equity backed group that also owns Tabs3, TimeSolv, ImagineTime and Rocket Matter.

DISCO: Is it cheaper than Relativity?

On small and mid-sized matters usually yes, because seats and analytics are included. On very large collections the volume charge often overtakes a negotiated Relativity arrangement.
