Turn your accounting firm
into an AI accounting firm
ACCOS takes every client's documents, reads them, matches them to the chart of accounts, exports to Express and reconciles — then leaves the monthly filings and a draft P&L waiting for you. PEAK and FlowAccount are under testing.
Your team reviews instead of types — so you can take on more clients without hiring.

Everything a firm needs, on one desk
ACCOS is built to be an accountant's desk, not a single tool — document work, tax work, client work and running the office itself all sit in one place, so you are not buying pieces from other vendors and wiring them together yourself.

The owner's work, not the accountant's

- Scheduled summaries sent to the team
What we don't do
And don't intend to
We do not replace your accounting program. ACCOS has no ledger of its own — the books stay in Express, or whichever system your client already runs. Not having to migrate is exactly why a firm can start next period instead of next year.
Some of these are optional modules you switch on as your firm needs them. "No need to buy another tool" means no second vendor to integrate — not that every module is on from day one.
