# Credit note

The `CreditNote` family — 3 operations.

A credit note is the reducing correction to an invoice — it gives value back, line by line, and always says why. Amounts are entered as positive magnitudes, the credit sign rides the document, over-crediting a line refuses, and settlement makes it final.
