Cancellation and Cancellations

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 maintain traceability.

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).

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. Enter the Billing module.
2. Search for the invoice to correct.
3. Choose "Cancel" (issues the linked credit note in AFIP).

The credit note will be linked to the original invoice and will adjust:

• Customer balance.
• Billing reports.
