LEDGER

Fix a mistake here and nothing disappears. The system writes an equal-and-opposite reversal, then a repost with the right numbers. Both are stamped, both stay visible, and both point back at the entry they correct. The original line is still there, still wrong, still explaining itself.

This isn't a policy we promise to follow. It's enforced one layer below the software: the database itself rejects an update or a delete on a ledger entry. Not the app — the database. Which means it holds even if something goes wrong in the code above it.

• Append only

  Entries can be added. They cannot be changed or removed by anyone, through any screen.

• Corrections

  A reversal plus a repost, each linked to the original. The arithmetic comes out right; the paper trail stays honest.

• No balances

  Nothing stores a running total. Every figure is added up from the entries at the moment you ask. There is no cached number to drift out of step with reality.

• Reproducible

  Re-run a March report next year and you get the March numbers. That's a consequence of the two rules above, not a separate feature.

• Whole cents

  Money is stored as whole cents with an explicit direction, so rounding can't quietly accumulate across a year of reports.

• Tax lines

  Each category carries its Schedule C line. Categorize a transaction once and the year-end summary groups straight onto the form your accountant is already filling in.

• Transfers

  Moving money between your own accounts — paying the card off from checking — is its own classification and is excluded from income and expense totals. Tools that treat a transfer as an expense double-count every month.

• Statement import

  CSV, OFX and QFX. Statements land in a review queue first and never write straight to the ledger; you confirm, and confirming is what creates the entry.

• No duplicates

  Overlapping statements are caught by a fingerprint on each row and flagged rather than imported twice. Re-uploading the exact same file is refused outright.

• Rules

  Recurring lines categorize themselves once you've taught them. Every entry records how it was categorized — by hand, by rule, or suggested and then confirmed by a person.

• From the CRM

  Invoices raised in Fieldamigo can flow in as income entries, so the books and the jobs aren't two separate stories about the same month.

The Ledger is off by default and switched on per instance. If your bookkeeping already works, leave it off — it's included either way, and it doesn't change what you pay (see pricing).
