Verifactu in Billdu: activation and requirements

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 activated.

Yes. To activate Verifactu you need an active paid plan: Lite, Standard or Premium. Trial and Free accounts can’t activate Verifactu.

Before you can activate Verifactu, your Business Profile must be complete and correct, including all required fields. Billdu checks this during the activation flow.

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.

From the start date, invoices you issue with Billdu in Verifactu mode will automatically generate a Verifactu record, which will be sent to the Spanish Tax Agency (AEAT).

Once an invoice is successfully Registered, it will include a QR code.

Once you activate Verifactu, you commit to the Spanish Tax Agency (AEAT) to send tax reports for every invoice you generate from the start date onward. Once you have made this commitment to the AEAT, it is not possible to generate invoices outside of a SIF (Sistema Informático de Facturación). If you decide to stop using Billdu after activating Verifactu, you will need to have another Verifactu SIF or use the tool provided by the AEAT.

Verifactu requires stricter invoice data quality because invoice data is prepared for official reporting to AEAT. That’s why Billdu applies extended validation for both:

If key identification fields are missing or incorrectly formatted, the report can be rejected — and you’ll see an error in the app.
