Received an error when registering the sequence?
If you receive an error when trying to register a sequence, see the most common causes below and what you can do in each case. ⚠️
1Error: "An error occurred in the registration process of this sequence. Please try again."
If the connection with the AT is active but you keep receiving this message, it may be due to one of two reasons:
AT server unavailable
The Tax Authority server may be temporarily unavailable and not accepting communications. In this case, you can wait a few hours and try again.
When there is a general problem with communications to the AT web service (affecting all accounts), InvoiceXpress shows an alert in our help center (the ? icon in the bottom right corner of the page).
Invalid data in the user credentials
Although the connection with the AT is shown as active, the error may be related to incorrect or invalid data in the user credentials.
💡 Tip: to follow the necessary steps, see the step-by-step guide to create and register sequences and obtain the ATCUD.
In these cases, we recommend creating a new user on the Finance Portal and adding those details to your InvoiceXpress account.
2Error: "The NIF associated with this account has no open activity."
If you opened your activity recently, the process may not yet be fully updated on the Tax Authority's side, which does not yet recognise the activity as open.
In these cases, we recommend waiting a few days and trying to register the sequence again.
3Error: "The registration of one or more sequences failed. It was not possible to register because a sequence with the same name is already registered with the Tax Authority."
You already have a sequence created and registered on your Finance Portal with the same name as the sequence you are trying to create.
In this situation, it is not possible to register the sequence through InvoiceXpress, nor to obtain the ATCUD codes for each document type of that sequence.
⚠️ Solution: create and use a new sequence, with a different name from the sequence already registered on your Finance Portal.

💬 Frequently asked questions
❓ What should I do if I get "An error occurred in the registration process of this sequence"?
If the connection with the AT is active, you can wait a few hours and try again, since the Tax Authority server may be temporarily unavailable. If the error persists, the cause may be incorrect data in your user credentials: in that case, we recommend creating a new user on the Finance Portal and adding those details to your InvoiceXpress account.
❓ What does the error "The NIF associated with this account has no open activity" mean?
If you opened your activity recently, the Tax Authority may not yet recognise it as open. Wait a few days and try to register the sequence again.
❓ Can I register a sequence with the same name as one already registered on my Finance Portal?
No. In that case, it is not possible to register the sequence through InvoiceXpress. Create and use a new sequence with a different name.
