Our Verdict
Clio wins on features, integrations, and ecosystem breadth. CosmoLex wins when your priority is having practice management and complete accounting in a single platform — eliminating QuickBooks and its integration friction. For solo and small firms already managing their own books, CosmoLex's all-in-one model often wins on total cost of ownership. For firms with dedicated accountants who need Clio's 250+ integrations and larger community, Clio remains the stronger long-term platform.
Frequently Asked Questions
Is CosmoLex cheaper than Clio when you factor in QuickBooks?
It depends on firm size. For a solo attorney: Clio EasyStart ($49) + QuickBooks Simple Start ($35) = $84/month vs CosmoLex Standard ($109/month) — Clio wins by $25. For a 5-attorney firm: Clio Essentials ($445) + QuickBooks Plus ($90) = $535/month vs CosmoLex Standard ($545/month) — nearly identical. At larger firm sizes and higher Clio plan tiers, CosmoLex often wins on total cost while delivering more integrated financial reporting.
Does Clio have built-in accounting?
No. Clio includes trust accounting (IOLTA compliant) and billing/invoicing, but does not include a full double-entry accounting system. For P&L statements, balance sheets, accounts payable, and complete bookkeeping, Clio requires integration with QuickBooks Online or Xero. CosmoLex is the main alternative that includes complete accounting built in.
Can you switch from Clio to CosmoLex?
Yes. CosmoLex has a migration team that assists with data import from Clio, including matters, contacts, time entries, invoices, and billing history. Expect a 2–4 week migration process. The most complex part is migrating historical trust accounting data — plan for careful reconciliation during the transition period.
Which is better for trust accounting — Clio or CosmoLex?
Both platforms include IOLTA-compliant trust accounting, but CosmoLex goes deeper. CosmoLex's automated three-way trust reconciliation (bank statement, trust ledger, and individual client ledgers) is more comprehensive than Clio's trust tools and generates more complete bar association compliance reports. For firms with strict trust accounting needs or that have undergone bar audits, CosmoLex's trust accounting provides greater peace of mind.
Does CosmoLex integrate with QuickBooks?
CosmoLex is designed to replace QuickBooks, not integrate with it. The platform includes complete double-entry accounting, eliminating the need for the QuickBooks integration. If your firm has existing staff who specifically need to work in QuickBooks, CosmoLex may create workflow disruption. However, most firms that switch report the transition is worth the elimination of dual-system management.
