Cancellation and credit notes

How to handle billing errors through credit notes and cancellations.

Last updated: 2026-09-09

Sometimes it's necessary to correct already issued invoices due to errors in data, amounts, or sale conditions.

Instead of deleting receipts (something not fiscally permitted), Sarah uses:

  • Credit notes to partially or totally reverse an invoice.
  • Debit notes to reverse a credit note issued in error.
  • Controlled cancellation flows that keep an audit trail.

Fiscal rules Sarah validates

  • Same party: when canceling, the reversal receipt must be issued to the same person (same CUIT) as the original. Sarah queries AFIP and compares with the registered customer before issuing.
  • Invoice A: only for Registered VAT (RI) customers with a valid CUIT.
  • Invoice B: not allowed when the customer is RI (Invoice A must be used).
  • Only sales invoices A, B, or C with CAE. A credit note is not canceled with the same button (that would issue a debit note).

When to use a credit note

Typical cases:

  • An incorrect amount was invoiced.
  • Products were returned after the sale.
  • The invoice was issued with the wrong customer.

Generate a credit note

  1. Open Invoices (or the sale detail).
  2. Find the A, B, or C invoice that has a CAE.
  3. Choose Cancel and confirm. Sarah requests the credit note from AFIP (opening a link is not enough: you must confirm).

After canceling:

  • The original invoice stays canceled and can still be printed (historical receipt).
  • The credit note can be printed (ticket or A4) from the same Print button: choose “Credit note”. On a canceled invoice the dialog opens on the credit note by default.
  • The list shows readable types (Invoice B, Credit note B), not a raw CAE dump.

The credit note is linked to the original invoice and updates the fiscal month (VAT is recorded in the credit note’s month).
