Where can I activate Verifactu in Billdu?
You can activate Verifactu only in the Billdu mobile app — go to Settings → Verifactu → Activate Verifactu to enable it.
It can’t be activated on the web. On the web, you can only see whether Verifactu is enabled.
Do I need a paid subscription to activate Verifactu?
Yes. To activate Verifactu you need an active paid plan: Lite, Standard or Premium. Trial and Free accounts can’t activate Verifactu.
What do I need to prepare before activation?
Before you can activate Verifactu, your Business Profile must be complete and correct, including all required fields. Billdu checks this during the activation flow.
Can I disable Verifactu after enabling it?
No. Once you start using Verifactu in Billdu, it’s a permanent setup for your company — you can’t switch it off later.
It’s not possible to “just try it once” and then revert back.
Even if you stop using Billdu, it doesn’t mean Verifactu stops applying to you — if you are required to use it, you still need to stay compliant with the rules.
Why do I need extended validation for supplier and client details?
Verifactu requires stricter invoice data quality. That’s why Billdu applies extended validation for both:
Supplier (your company) details in your Business Profile
Client details on invoices (e.g., required identifiers)
Why does Billdu require “extended validation” for supplier and client details in Verifactu mode?
Because in Verifactu mode, the invoice data is prepared for official reporting to AEAT, so the key identification fields must be complete and correctly formatted. If identifiers are missing or wrong, the report can be rejected (and you’ll see an error in the app).
