When invoicing in Verifactu mode, Billdu requires your client’s required info such:
Name
If your client is a Spanish client - NIF (their tax identification number).
If your client is not a Spanish client - CIN (their company identification number).
Email address
Postal code
In Verifactu context, having these identifiers correct helps ensure the invoice data can be validated and reported properly.

Does Billdu check if the NIF/CIN “exists”?
Billdu first checks that you filled in the required client identifiers (NIF/CIN) in the app — without them, the invoice can’t be uploaded to Verifactu.
During the Verifactu upload process, we also validate the client details as much as possible (for example: format checks and availability/existence checks where applicable). If something looks wrong, we’ll show you an error so you can fix it before continuing.
What about B2G invoicing?
At the moment, submitting B2G invoices to Verifactu is not supported.
We are currently exploring possibilities to implement this feature in the future. We understand this functionality is important for many Spanish businesses and will share updates as soon as more information becomes available.
