## Two different jobs
- **CosmoLex** is built around built-in legal bookkeeping (general ledger) and trust/IOLTA accounting — replacing separate accounting software.
- **HammerLex** is built around operational profitability — live P&L/margin by matter, client, and timekeeper — and all-in-one practice ops including staff/HR. It integrates with QuickBooks Online rather than replacing it.

## TL;DR
- **HammerLex if** your priority is profitability visibility and all-in-one operations, and you're happy keeping the books in QuickBooks.
- **CosmoLex if** you want built-in legal bookkeeping and trust/IOLTA compliance inside the platform, with no separate accounting tool.
