About E-Rechnung-Check

For E-Rechnung-Check it reads sections 14 and 27(38) of the German VAT Act, sections 33, 34 and 34a of the VAT Implementing Ordinance, the Federal Finance Ministry letters of 15 October 2024 and 15 October 2025 and the KoSIT (XRechnung 3.0.2) and FeRD (ZUGFeRD 2.5.2) specifications, and turns them into tools that run entirely in your browser. It is not an authority or a tax adviser and gives no tax advice.
Why this site exists
With the German e-invoicing mandate, many small businesses face a file they cannot read and a duty whose stages are hard to follow. Many offers on the subject are part of software you are expected to buy, require an account or upload invoices containing customer data to third-party servers. This site aims for the opposite: settle the mandate in a minute, and open, check and create files without any invoice leaving your device.
Who publishes it
The publisher is Radif Partners, a company that builds tools from public rules and data. Radif Partners is not an authority, a tax adviser or a law firm. The site is not affiliated with the Federal Ministry of Finance, KoSIT, the German e-invoicing forum FeRD or any software vendor, and uses none of their logos. It sells no software, contains no affiliate links and is funded by advertising at the edge of the pages.

Where the rules and formats come from
The mandate and its exceptions come from the VAT Act, the VAT Implementing Ordinance and the Finance Ministry letter of 15 October 2025. The formats follow the specifications of KoSIT for XRechnung 3.0.2 and of FeRD for ZUGFeRD 2.5.2. We checked generated files with the official KoSIT validator and with veraPDF. How we calculate and check is on the method page; how we correct, in the editorial policy.
Your data
The tools process invoices only in your browser. There is no account, no form that sends invoice data to us and no storage for your files. Details on audience measurement are in the privacy policy.
What the site does not do
It does not deliver invoices for you, does not replace bookkeeping and gives no tax advice. The results rest on statute and standard; whether an invoice is proper in your individual case is for your tax adviser and the tax office to judge.
