Two modules
The books, and the firm around them.
Some practices only want Finn on the ledger. Some want the whole firm on it. They are two modules, not one long list. Finn cannot connect a live bank feed or add a user, so anywhere it writes, it asks first and you stay the one who reviews and signs.
The books
Finn runs the books.
Bookkeeping handled end to end, with your team reviewing and signing off. Take on more clients without adding bookkeeping headcount at the same rate, and put more of your time into client relationships and winning work.
You can run just this, and keep the practice software you already have.
10 featuresPractice management
Build the practice.
Bring your client work, team and practice economics together. Finn helps you manage the practice as well as the books, giving you a clearer view of capacity and margins as your client base grows.
Use it alongside the books, or keep your existing practice management software.
