Installation and setup

Install the module from the PrestaShop back office and open its configuration. Once installed, it is ready to go with sensible defaults: R series, numbering reset every year, automatic issue with every refund and type R1.

Module customisation

From the configuration you can:

• Enter the issuer's tax ID (NIF) printed on the PDF.
• Choose the corrective invoice series and whether numbering resets every year (R2026-000001).
• Enable or disable automatic issue with every credit slip.
• Set the default type (R1 to R5) and reason, and use R5 for customers without a tax ID if you issue simplified invoices.
• Decide whether customers can download their corrective invoices from their account.

Day-to-day use

You refund from the order as usual and the corrective invoice is issued automatically, with its PDF on the order page and under Orders > Corrective invoices. To correct an invoice without a refund, choose the invoice, the type and the reason, then cancel the entire invoice or add free-form lines. At the end of the month, export the CSV by date range for your accountant.
