4 books on the account. 1 key.
01 · The cost
Hundreds a month before you bill an hour.
Mainstream accounting software charges per company file: 25 clients is 25 subscriptions, and the bill grows with every client you win.
Write-up work is data entry, which is what your AI is good at: it categorizes, matches transfers, and preps the close in every book from one connection. You spend the hours on review and advice, the part clients actually pay for.

02 · The engagement
Your AI does the work. You review and sign off.
01 Open · create_business
Each client is its own business in your account: own chart of accounts, transactions, reports, and lock dates. Creating one takes a sentence (“set up books for Ramirez Plumbing LLC”) and the default small-business chart is seeded instantly.

Books open, ready for the first statement.
02 Backlog · bulk_categorize
Hand it the client’s statements. Bulk import and bulk categorize are built as migration workhorses: batches dedupe on import, one bad row never blocks the rest, and transfer matching keeps inter-account moves from double-counting.
Here is June for Coffee Company. Import it and categorize everything.

Jun 28 · Gusto, payroll run
Re-derives every rule from the journal itself.
Staff join as full members and work the book with you, in all but billing. A client signs in to a review-only view of their own book.
They see the dashboard, the reports, and the charges you asked them about. Nothing they do can change a number.

Questions
Nothing per client: unlimited client books are free on one account. Paid plans cover live bank feeds, priced by connected accounts pooled across all your books, not per client, plus AI Bookkeeping and Autopilot on Growth and Scale.
Yes. Postings are immutable with corrections as linked reversals, periods lock after close, and every write your AI makes sits in an append-only audit log you can hand a reviewer.
Yes. Invite staff by email as full members (co-owners of the book), and give clients a review-only role: they see their dashboard and can explain charges you flag, without any ability to write. API keys can also be scoped to specific books or made read-only, so your AI or a client’s assistant only ever touches what it should.
Whichever you already have. Claude and ChatGPT both connect in about a minute, and Claude Code or any MCP client works with an API key. Your AI, your prompts, on a ledger that enforces the rules; or use the optional built-in assistant on Growth and Scale, which works through the same audited tool surface.
They are the sweet spot: your AI ingests months of statements in one pass, and you review the flagged queue. Engagements that took a weekend of data entry compress to an afternoon of review.
Everything exports in one click per book, as a ZIP: transactions, general ledger, chart of accounts, journal entries, tags, and assets as CSV, plus your receipts and their files. The 1099 report gives you total paid per vendor with the year’s reporting threshold applied ($2,000 for 2026 payments, $600 for earlier years) and missing W-9s flagged.
Pick your messiest backlog client, hand your AI the statements, and compare the hours.
Nothing to install. Every plan has unlimited books.
