How this works - feature 421 Reduce what a customer owes: discount, return or mistake.

Concepts

  • Posting at the INVOICE rate: Dr Sales returns / Dr Output VAT / Cr Accounts receivable.
  • Sales returns is a contra-revenue account: it lowers revenue in the P&L without touching the original sale.
  • Output VAT goes down too, so the VAT report (423) shows the credit note as a negative line.
