When invoicing in Verifactu mode, Billdu requires the following information from your client:
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 upload process, we also validate the client details - format checks and availability/existence checks where applicable.
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.
