What is e-invoicing?

An e-invoice isn't just a PDF sent by email. It's an invoice created in a structured, machine-readable format - or reported directly to the tax authority - so it can be processed automatically and can't be quietly changed after it's issued.

Governments across the EU are making e-invoicing mandatory to cut fraud and simplify tax reporting. The exact system is different in every country: Spain uses Verifactu, Belgium uses Peppol, Germany uses XRechnung and ZUGFeRD, France uses Factur-X, Italy uses the SdI. The deadlines and who's affected vary too.

That's the hard part - and it's the part Billdu handles for you. You keep invoicing the way you always have, and Billdu takes care of the format and reporting your country requires in the background.

Who needs to use e-invoicing?

If your country has an e-invoicing mandate, it likely applies to you - and increasingly that includes freelancers, sole traders and micro-businesses, not just large companies. Whether you're in scope, and from when, depends on your country and your business type.

Billdu is built for exactly this end of the market: freelancers, the self-employed and small businesses that need to stay compliant without an accountant's IT budget or enterprise software.

E-invoicing FAQ

What is e-invoicing?

E-invoicing is the process of issuing invoices in a structured electronic format, or reporting them directly to the tax authority, so they can be processed automatically. It's different from emailing a PDF - the data is machine-readable and can't be silently changed after issue.

Is e-invoicing mandatory?

It depends on your country and business type. Many EU countries have introduced or are phasing in mandatory e-invoicing, with deadlines that differ by business size. Check your country's system in the section above for specifics.

Is an e-invoice the same as a PDF invoice?

No. A PDF is a readable document; an e-invoice carries structured data the receiving system or tax authority can process automatically. In some systems your customer still receives a readable PDF, while the structured record is reported or exchanged in the background.

Does Billdu support e-invoicing in my country?

Billdu currently supports Verifactu in Spain and Peppol in Belgium, with Germany, France, Italy and Poland on the way. Open your country's card above to see what's available today.

Do I need e-invoicing as a freelancer or sole trader?

Increasingly, yes - many mandates now reach freelancers, the self-employed and micro-businesses, not just large companies. Whether and when it applies depends on your country's rules.

Which Billdu plan includes e-invoicing?

E-invoicing is available on Billdu's Standard and Premium plans, on both mobile and web.

Do I have to change how I invoice?

No. You create invoices in Billdu the same way as always; the required format conversion or tax-authority reporting happens automatically in the background.
