Why offer a free e-invoice generator?

Across the EU, the move to mandatory PEPPOL BIS 3.0 e-invoicing is well underway. Estonia, Latvia, Lithuania, Italy, France, Belgium, Germany and others have either mandated or scheduled mandates for B2G and B2B electronic invoicing. Small businesses and freelancers should not be priced out of compliance.

The free aiDoks generator gives every business a way to create legally valid PEPPOL BIS 3.0 e-invoices β€” UBL 2.1 XML format, fully compliant, validated β€” without a subscription, without a credit card, and without per-invoice fees. Premium features (AI OCR for PDF conversion, business partner management, reusable templates) are available on a free aiDoks account, with a Pro upgrade only if you need higher AI OCR volume.

Are these invoices legally valid?

Yes. Every invoice produced by the free generator complies with EU Directive 2014/55/EU on electronic invoicing, the EN 16931 European norm, and the PEPPOL BIS Billing 3.0 specification. They are recognised across all EU member states for B2G transactions and accepted by every PEPPOL Access Point.

Do I need any technical knowledge to use it?

No. You fill in a simple form β€” supplier, buyer, dates, line items, VAT rates β€” exactly like a paper invoice, and aiDoks generates the PEPPOL-compliant UBL 2.1 XML in the background. You never need to touch raw XML, schemas or PEPPOL specifications.

Are invoices created here legally valid?

Yes. Invoices generated by aiDoks comply with EU Directive 2014/55/EU on electronic invoicing, the EN 16931 European norm and the PEPPOL BIS Billing 3.0 specification. They are recognised as legally valid e-invoices across all EU member states.

Yes β€” with a free account you get Business Partner management. Save suppliers and customers once, then auto-fill the form with one click on every subsequent invoice. You can also save full invoice templates with default values and field layouts.

What invoice formats do I get when I export?

Every generated invoice can be downloaded as PEPPOL-compliant UBL 2.1 XML for electronic exchange and as a styled PDF for archiving, email or printing.
