```

## Specification

Per-line account and full dimensions — a single invoice legitimately hits four departments. Default coding suggested from this vendor's history, shown **as a suggestion** with its basis. Source document attachment is **required**; a bill without one cannot be approved.

Early-payment discounts surface as a decision with the annualized return: "Pay by 12 Oct to save $240 (2%) — a 37% annualized return."

## Rules this component obeys

Money is minor units, never floats. `null` is not `0` and neither is redacted. Negatives render in accounting parentheses with the parenthesis column reserved on both sides. Debit and credit are two columns. Per-currency decimal places. Polarity is explicit — up is not always good. Every figure states its period, entity, currency, basis and as-of.
