Everything you need for e-invoicing

Three ways to a finished XRechnung – whether you work once, regularly, or automated.

🧹

Data-minimising – no data storage

We do not store your invoice contents permanently: they are only processed briefly to generate the file and then deleted automatically. Only an anonymous log remains – maximum privacy, minimal risk.

✏️

Form editor

Enter invoice data, validate directly in the browser and export as XRechnung XML, standard PDF and hybrid PDF at the click of a button.

📄

PDF scanner

Upload existing invoice PDFs: the scanner automatically detects line items, amounts and address data and generates valid XRechnung XML.

🔌

REST API

JSON endpoints for direct integration into ERP, accounting software or custom workflows — with API key, rate limiting and full EN 16931 validation.

✅

Validation

Every invoice is checked against all EN 16931 mandatory rules and CIUS XRechnung 3.0 — errors are clearly described, not just output as error codes.

📊

Invoice history

All created invoices in your personal dashboard — searchable, downloadable and with monthly quota overview.

🔁

Recurring invoices

Set up monthly or quarterly invoices and have them generated automatically — with your own sender profile and saved recipient addresses.

No download, no setup — directly in your browser.

Frequently asked questions

Straight answers — no marketing speak.

An XRechnung is an XML data format for electronic invoices implementing the European standard EN 16931. Since November 2020 it is mandatory for invoices to German federal authorities. From 2025, the e-invoicing obligation applies progressively to B2B transactions as well (§ 14 UStG).

Every invoice is checked against the mandatory rules of EN 16931 and CIUS XRechnung 3.0 before export. Errors are reported with specific descriptions — not as cryptic error codes. However, we cannot accept liability for the tax accuracy of the data you enter.

XRechnung is a pure XML format (UBL 2.1 or UN/CEFACT CII). A hybrid PDF is a standard PDF with embedded XRechnung XML — readable by humans and machine-processable. Both are EN 16931-compliant. Which one you need depends on your client.

No – in data-minimal mode we do not store invoice contents permanently: they are automatically deleted shortly after creation, leaving only an anonymous metadata log. Signed-in users can enable permanent archiving in their settings (if available). We do not sell user data. Details can be found in our privacy policy.

Yes. The REST API accepts JSON and returns XML or PDF. Documentation and an interactive test area are available under API documentation API keys can be created in the dashboard.

Yes. The Free plan lets you create up to 5 documents per month at no cost – XRechnung as XML and PDF, right in your browser, no payment details and no expiring trial. If you need more volume, hybrid PDFs or API access, you can upgrade to a paid plan at any time.

Since 1 January 2025, all businesses in Germany must be able to receive e-invoices. Sending follows a transition period: from 2027 e-invoicing becomes mandatory for companies with more than €800,000 in prior-year revenue, and from 2028 for everyone. Many clients and public authorities already require e-invoices today – switching early saves you the deadline stress.
