Your clients can no longer refuse a structured e-invoice.

From Sept 1, 2026 you must be able to receive e-invoices — and from Sept 1, 2027 small businesses in France must issue them. The transition deadline is not the day to find out your PDFs are wrong.

FAQ

Is this legal or tax advice?

No. We run a technical check of your invoice against the published EN 16931 rules. For fiscal advice, talk to your accountant.

Which formats do you accept?

PDF invoices with embedded XML (Factur-X, ZUGFeRD) or raw CII XML. Plain PDFs are detected and the converter is offered.

What happens to my files?

Processed on servers in the EU, auto-deleted after 24 hours, never shared, never used for anything else.

Which profiles are supported?

Factur-X MINIMUM to EXTENDED, ZUGFeRD, XRechnung, and the EN 16931 core profile.

Do you transmit invoices to the tax authorities?

No. We validate and convert only; transmission goes through your invoicing software or a certified platform (PDP).

Why did my valid-looking invoice fail?

Most common causes: no embedded XML, totals off by more than 0.01, invalid VAT or IBAN format, missing buyer reference.
