Frequently Asked Questions
Do I need a digital certificate to get started?
You do not need to install a digital certificate to generate invoices and records in the VERI*FACTU mode described in our responsibility statement.
What is remitted to the AEAT in VERI*FACTU?
Invoicing records are remitted, not the complete invoice. Status depends on the AEAT service response.
Can I issue invoices from my phone?
Yes, the web portal is fully responsive and works on any device.
What happens if I make a mistake on an invoice?
You can issue a corrective invoice at any time from the portal.
How many users can I add?
It depends on your plan; enterprise plans allow unlimited users.
Can I assign different roles and permissions?
Yes, you can define admin, billing and read-only roles.
What format should I use to import my catalog?
We accept CSV and Excel files using a template we provide.
Can I manage several invoicing series?
Yes, you can set up multiple series and numbering by department.
How do I authenticate my API requests?
Via an API Key in the Authorization header or with OAuth 2.0.
Is there a testing environment?
Yes, we offer a full sandbox that never sends real invoices to the AEAT.
What should I do if I get an AEAT error code?
Every response includes the code and a description; see our error guide.
Do you have rate limiting?
Yes, configurable per plan; webhooks warn you as you approach the limit.
