Partner practices
Build your AI-native practice on AccountsOS.
Whether you are starting a firm from scratch or moving an established one to an AI-native way of working, AccountsOS does the work, runs the firm and helps it grow. Finn does the production; your team reviews and signs.
AccountsOS · The practice desk

Two ways in
New firm or established firm.
Do the work
Do the work.
Finn does the production on a real double-entry ledger. Your team reviews the exceptions and signs.
Books and reconciliation
Finn categorises, reconciles and chases what is missing, across every client at once.
VAT, with live MTD filing to HMRC
Returns drafted where the books are clean. Filed to HMRC through HMRC-recognised MTD VAT software once your team signs.
Annual accounts and Companies House filing
Accounts prepared, and confirmation statements and accounts e-filed to Companies House.
Review packs your team signs off
Everything a reviewer needs in one pack. Finn never files or signs. A person does.
AccountsOS · The checks, the exceptions, the sign-off

Every month-end close, VAT return and set of accounts gets a review pack: the checks Finn ran, what needed a person, and who cleared it. Sign it off and it locks.
Run the firm
Run the firm.
One desk for the work that needs a person, across every client.
AccountsOS · Invite the team, allocate the work

Bookkeepers see their own desk and the clients allocated to them. Admins see everything. Allocate clients yourself or let the team pick up unallocated ones. No per-seat fee.
Grow the firm
