01
Chasing receipts
Forward them, drop them in, or let the bank feed pull them. Each one lands on the transaction it belongs to.
02
Categorizing by hand
The agent proposes the category, the split, the month. You skim a list and confirm.
03
Rebuilding the year in April
The return is built from the books you already closed. Every number opens to the transactions behind it.

The architecture
Bookkeeping isn't hard because money is complicated.
It's hard because the tools want you confused.
QuickBooks keeps adding workflows, menus, and paid experts. Bookkeepers price by complexity. So we built an accounting system from the ground up: immutable, verifiable, auditable, agent-native.
The ledger is the source of truth.
We rebuilt the ledger from first principles. It is still double-entry. Still GAAP-compatible.
But every entry now has a source: prepared, reviewed, and confirmed in the ledger. No shadow spreadsheet, no separate “final” books.

Agents make mistakes. So we limit what they can do.
An AI agent that posts journal entries unsupervised is a liability. One hallucinated category and your P&L is wrong.
So we don't let it. You preview the change with your agent. You confirm when it looks right. The diff visible, the rationale attached, the source document linked.

Answering an audit request.
You got audited. The IRS asked for support on five expenses. Ask the agent: "export the records behind these expenses". It pulls up the invoice, the receipt, the bank transaction and the notes behind every one.
