What is law firm accounting?

FAQ

Law firm accounting and AI bookkeeping FAQs.

What is law firm accounting?+
Bookkeeping and reporting for law firms: fees collected, payroll, rent, vendor and expert costs, and results by practice area.
How does AI bookkeeping work for a law firm?+
Zeni's AI Accountant codes the firm's deposits, vendor bills and software with its reasoning shown, matches receipts and reconciles your accounts. Your Zeni team reviews the work and closes the books each month.
How are vendor and expert bills approved?+
Bills go through Bill Pay with multi-level approval flows, so nothing is paid until the right person signs off.
Can Zeni report results by practice area or matter?+
Yes. Tag each one as a class or project, and Zeni reports profit and loss, balance sheet and cash flow by class or project.
Which ledger does Zeni use?+
QuickBooks Online. Zeni reads and writes to it as your ledger of record.
Who sets up and manages the AI agents?+
Zeni does. Our team deploys the platform, manages the AI agents and reviews the work, and you approve what needs your sign-off.

Yes. Lower-confidence transactions go to a review queue instead of posting, your Zeni team reviews the close, and the AI CFO is in beta, so check anything important against the books.
