Terms of use

These terms apply to your use of okinvoice.eu, including the guides, the e-invoice validator and the deadline checker. By using the site you accept them. The site and its tools are free, and you do not need an account.

Information, not advice

OkInvoice explains the B2B e-invoicing rules in Germany, France and Belgium and links to the official sources. We research our pages carefully, as described in our methodology, but the rules change and every business is different.

Nothing on this site is tax, legal or accounting advice, and no adviser-client relationship arises from using it. Before you make decisions that depend on your own situation, check the official sources or ask a tax adviser.

What the validator checks

The validator checks your file against the published official rule sets: the European standard EN 16931 (CEN), the KoSIT XRechnung rules and the OpenPEPPOL BIS rules. Its result tells you whether your file meets those rules as far as they can be checked automatically.

A validator result is not an official certification, and it does not prove that an invoice is correct in content or meets every legal requirement for an invoice. We give no warranty that a file accepted by the validator will be accepted by a particular recipient, platform or access point. Many recipients and platforms apply extra rules of their own.

What the deadline checker tells you

The deadline checker gives a general answer based on the information you enter and the rules as we understand them on the date shown. It cannot cover every special case. If your situation is unusual, confirm the result with the official sources or a tax adviser.

Availability

We offer the site and its tools free of charge and as they are. We try to keep them available and accurate, but we may change, interrupt or stop any part of the site at any time without notice.

Liability

We are liable without limitation for damage caused intentionally or through gross negligence, for injury to life, body or health, and where mandatory law provides for liability.

In all other cases, and as far as the law permits, we are not liable for damage resulting from the use of the information or tools on this site, in particular from relying on a validator or checker result. Because the site and its tools are provided free of charge, this limitation applies to the extent the applicable law allows.

Links to other websites

Our pages link to external websites, such as official sources and software vendors. Those websites are not under our control, and their operators are responsible for their content. We checked the linked pages when we set the link, but we cannot monitor them constantly. If you tell us about a broken or unlawful link, we will remove or fix it.

Some links to software vendors are affiliate links. How they work is explained in our affiliate disclosure.

Content and copyright

The texts, tables and graphics on okinvoice.eu are protected by copyright. You may read, print and share links to our pages, and quote short passages with a link to the source. Copying larger parts or republishing them requires our permission. The official rule sets used by the validator remain subject to the licences of their publishers.

Privacy

How we handle personal data is explained in our privacy policy and our cookie policy.

Governing law

These terms are governed by the law of [COUNTRY OF OPERATOR]. If you use the site as a consumer, this choice of law does not take away the protection of the mandatory rules of the country where you live.

Changes and contact

We may update these terms when the site or the law changes. The version published here applies, and the date at the top shows the latest change. For questions, write to hello@okinvoice.eu or use the contact form. The operator's details are in the imprint.
