In accordance with the requirements of the Portuguese Tax Authority (AT), all companies operating in Portugal must issue fiscal documents that include an ATCUD code and a QR Code. RoomRaccoon is a certified invoicing system (certification number 2767) that allows you to issue invoices and other financial documents in compliance with Portuguese law.

What is the ATCUD

The ATCUD (Unique Document Code) is an alphanumeric code assigned by the Portuguese Tax Authority to each registered invoicing series. This code must appear on all fiscal documents you issue, including invoices, receipts, invoice-receipts, and credit notes.

In addition to the ATCUD, RoomRaccoon automatically generates the QR Code required by the AT on every document.

Follow these steps to ensure your RoomRaccoon account is compliant with AT regulations:

1. Register your invoice series on the Finanças portal

   • Log in to the Portal das Finanças.

   • Register the invoicing series you use in RoomRaccoon.

   • During registration, you will be asked for the RoomRaccoon certification number: 2767.

   • After registration, the AT will assign an ATCUD code for each document type (Invoice, Receipt, Invoice-Receipt, and Credit Note).

2. Add your ATCUD code to RoomRaccoon

   • Go to Settings → Billing in your RoomRaccoon account.
