Books Builder
Build the categorization map first — before you touch a single statement. Feed it last year's categorized books (or one fresh statement) and it drafts your chart of accounts and vendor rules, then an AI accountant reviews every account: business vs personal, what's a real deduction, what's just a transfer — and flags the few judgment calls that actually move your taxes, biggest dollars first. Save the map, then reconcile a whole year in minutes. Your numbers never leave your browser.

🔒 What this touches: your file is parsed in your browser and never uploaded. For the AI accountant review we send only short text descriptions and per-account totals — never amounts per line, never dates, never the file. The mapping you build lives in this browser only; export it to keep it.

Your draft map
Chart of accounts — edit freely · the accountant pass fills tax lines next
One per line: Name | Code | kind | tax line | business line. kind = income / expense / transfer / personal (transfer + personal are excluded from the P&L).
Rules
Vendor keyword → account, ranked by dollar impact. First match wins. Trim any that look too broad.
AI accountant review
An accountant pass sets each account's tax treatment and surfaces the judgment calls that matter — ranked by dollar impact. Accept or adjust each. Nothing is finalized until you say so.
A full chart of accounts can take up to a minute — the accountant is reading every account and ranking the judgment calls by dollar impact. Hang tight.
Reviewed chart of accounts
Sources & business lines
Each card / bank account becomes a source. The Filename contains text is how the Reconciler recognizes that account when you drop its statement — set it to a unique part of the file name. A dedicated business card can name a default expense account so anything unmatched on it lands there.
One per line: Label | Business line | Filename contains | money-in positive? | default expense account. money-in positive? = yes for banks/Chase, no for AMEX-style cards.
Your mapping is ready 🎉
Saved in this browser. Export it to back it up or move it — the file is fully compatible with the Statement Reconciler: import it there, then drop a year of statements and they sort themselves.
In the Reconciler: Manage mapping table → Import, pick this file, then drop your statements. Your map does the rest.
Set your books up once — then never categorize by hand again → This builds the map. The deeper playbook — multi-entity charts, recurring runs, and a mapping that keeps learning year over year — lives free inside AI for Operators on Skool.Why build the map first
Last year's pain wasn't reconciling — it was building the categorization reactively: run the statements, see what's wrong, fix one transaction, run again. The map is the real asset, and you were discovering it after the fact.
This flips it. You already have a year of decisions sitting in last year's books — so we mine your own chart of accounts and vendor rules out of it, then put an accountant's eye on the handful of calls that change your tax outcome: what's personal, what's a transfer (not a deduction), which income is a separate schedule. Decide those once, up front. Then reconciling is just dropping files.
