Correct an invoice

A released invoice cannot be edited. When the invoice was right but the amount is now wrong, issue a correction (Rechnungskorrektur) that credits part of it. The original stays exactly as it was sent.

  1. Open the released invoice and choose Correct Invoice from the ⋮ menu.

  2. Enter the Reason — the complaint, the discount agreed, the goods returned. It prints on the document.

  3. Tick the lines to credit. Nothing is ticked to begin with: crediting every line in full is a cancellation, not a correction.

  4. Set Quantity and Credit per unit on each ticked line. Both start at what the line was billed. Leave the price to credit whole units; lower it to credit a reduction on units the customer keeps.

  5. Confirm. The correction is created and released under its own number, and opens straight away. It can no longer be edited.

Quantity Credit per unit
Two of five pieces came back 2 as billed
10% off all five pieces 5 a tenth of the price

Both produce the same kind of document. The second is how a goodwill discount reaches a customer who keeps everything they bought.

A correction cannot credit more than a line billed, in units, per unit, or in total across corrections. Once every line is credited in full, or the invoice has been cancelled, Correct Invoice is no longer offered.

The order stays fully invoiced. Five pieces were delivered and five were billed, and crediting money afterwards does not undo either — so the order does not reopen and the lines are not offered for billing again.

Bringing returned goods back into stock is a separate act: Record a movement.

The released correction reads in the journal under Corrections — Invoice an order.

Correct when the invoice was right and only the amount has changed. Cancel when it should never have gone out — Cancel an invoice reverses it in full and reopens the order for billing.

Why the two differ, and what each carries into the e-invoice, is in Cancellations and corrections.
