Certified invoicing

Activate the certification of your invoices

Your invoices in Forsnaps are issued by software certified by the Portuguese Tax Authority (AT). Only one step remains, done by you once only: creating a sub-user on the Portal das Finanças that authorises the automatic communication of invoicing series (ATCUD). It takes about 5 minutes.

1

Sign in to the Portal das Finanças

Go to portaldasfinancas.gov.pt and sign in with the company's tax number (NIF) and password.

2

Open User Management

In the portal's search box type gestão de utilizadores and open the service “Autenticação de Contribuintes — Gestão de Utilizadores” (Taxpayer Authentication — User Management). Click Criar Novo Utilizador (Create New User).

3

Create the sub-user

Give it a name (for example Faturacao) and set a password. Keep this password safe — you will need it in step 5.

4

Authorise the communication of series

In the list of authorised operations, tick “WSE — Comunicação e Gestão de Séries por Webservice” (communication and management of series by web service) and submit. The portal shows the new user's identifier in the format 123456789/1 (your tax number (NIF), a slash and a number).

5

Give us the credentials

Enter the identifier (123456789/1) and the password in the subscription form — or, if you have already subscribed, send them to info@forsnaps.com and we will activate it for you. From then on it's done: series and ATCUD are communicated automatically.

Frequently asked questions

Is this safe? Yes. The sub-user only has the permission you ticked in step 4 — communicating invoicing series. It gives no access to the rest of the Portal das Finanças or to your tax data.

Do I have to repeat this? No. It is done once only; after that, communication with the AT is automatic.

What if I don't do it right away? You can use Forsnaps as normal, but your invoices are only certified (with ATCUD) after this step. You can complete it at any time.
