Compliance is mandatory. We turn it into protection too: every e-invoice per EN 16931 (ZUGFeRD, Factur-X, XRechnung), validated with the official KoSIT validator, plus an IBAN fraud check that catches manipulated bank details before you pay. For non-technical users and developers alike, built and operated by FHC+P, live at sichere-erechnung.de.
Since 2025, German companies must be able to receive e-invoices. The obligation to issue them follows in stages through 2028. A PDF sent by email is not an e-invoice. Companies that don't adapt risk rejected invoices, delayed payments, and trouble with the tax office. No XML, no mapping, no coding required, you provide the data as you have it, we turn it into a compliant e-invoice.
The issuer's IBAN is matched against your supplier history, check digit, country vs. registered address, known fraud accounts. A warning before you pay the wrong account. An endpoint no competitor offers.
ZUGFeRD 2.x / Factur-X as PDF/A-3 with embedded CII XML, validated against the official KoSIT validator, VAT ID verified live via EU VIES. XRechnung-checkable, fully compliant with §14 UStG.
Paste text or an Excel row via AI import, and the AI produces the structured invoice. Plus a classic form or no-code Excel upload for many invoices at once. For developers, a lean REST API; for SaaS vendors, white-label via iframe or API.
Outgoing invoices are cryptographically signed (Ed25519) and carry a QR code. Your customer scans it and instantly sees: genuine, unaltered, correct IBAN, protection against invoices faked in your name.
Every invoice automatically carries a GiroCode (banking app scans, everything pre-filled) and a "pay now" link. Plus receivables management with reminder stages, automatic late-payment interest, and collections handover.
Connect Outlook/IMAP (read-only), every incoming e-invoice is automatically checked: KoSIT compliance, PDF-vs-XML tampering, duplicates, and IBAN matching. Warns at the point of receipt, earlier than bank-side payment verification.
Form, AI import, or Excel upload. We handle the format, XML, and compliance. The result is a single file accepted everywhere.
A lean REST API for accounting, ERP, or your shop, invoice data in, a legally compliant e-invoice out, automatically.
Embed the invoice form via iframe or API in your own corporate design, or bring the IBAN fraud protection as an API (/v1/check) into your own software.
sichere-erechnung.de is built and operated by FHC+P, hosted in Germany, GDPR-compliant. We use the API in our own products too, including our CRM. Fair pricing from €9/month as a flat rate, or pay-per-use with credits that never expire, getting started is free with trial credits.

Since January 1, 2025, German companies must be able to receive e-invoices. The obligation to issue them follows in stages through 2028, depending on company size. A PDF sent by email is not an e-invoice.
When checking an incoming invoice, the issuer's IBAN is compared against your supplier history. If it deviates, the check digit is wrong, or the same IBAN suddenly appears for a different supplier, you get a warning before you pay the wrong account, including a blocklist for known fraud IBANs.
No. The web form, AI import (paste an Excel row or free text) or no-code Excel upload produce compliant ZUGFeRD invoices without XML, mapping, or coding. Software vendors also get a lean REST API.
As a monthly plan from €9/month, or pay-per-use with credits that never expire (from €9). Getting started is free with trial credits. Current pricing and details at sichere-erechnung.de.
