01
CERTIFIED ACCESS POINT
Peppol network
Invoice-Portal is a certified Peppol access point with its own SMP. Recipients are looked up by participant ID, and the invoice goes out in the format they support.
02
SMTP OR INVOICE-PORTAL
E-mail dispatch
Where the recipient is not on a network, the invoice is delivered by e-mail – either from your own mail server over SMTP or directly from Invoice-Portal.

B2G AND AUTHORITIES
German public sector
Invoices to federal and state bodies are routed to the portal each authority uses, with the Leitweg-ID carried in the document.

COUNTRY PLATFORMS
Other national systems
Several countries run their own clearance or exchange platforms. Invoice-Portal handles the local format and the local route.
Workflow
From your system to the recipient
Every invoice runs through the same six stages — no matter which method or channel you use.
1
Hand over
Upload, API, SFTP, e-mail, EDI or an ERP connector - mixed methods per department are fine.
2
Validate
EN 16931 rules, schema, tax logic, totals and recipient IDs - errors in plain language.
3
Convert
XRechnung (UBL or CII), ZUGFeRD, Peppol BIS or a country format - attachments included.
4
Route
Recipient look-up picks the channel: Peppol, portal, e-mail or a direct interface.
5
Track
Sent, accepted, rejected or awaiting correction - visible in the portal, pushed back to your ERP.
6
Archive
The structured original is stored unchanged and audit-proof for the retention period.
This internationally accepted standard for information security management confirms compliance with the highest security standards in the development and hosting of the platform.
The portal is hosted in state-of-the-art data center parks operated by Hetzner Online GmbH in Nuremberg and Falkenstein and Ionos SE in Frankfurt, which are ISO27001-certified.
Which formats can Invoice-Portal send?
XRechnung in UBL and CII syntax, ZUGFeRD / Factur-X, Peppol BIS Billing 3.0 and PINT, plus country formats such as FA(3) for KSeF. Source data can arrive as XML, CSV, IDoc, a custom layout or a PDF created in the portal.
Do I need to change my ERP system?
No. Invoices leave your system the way they do today – by SFTP, API, e-mail or a connector. The conversion into the required e-invoice format happens in Invoice-Portal.
How does the recipient get the invoice?
Invoice-Portal looks the recipient up and picks the channel: the Peppol network, a public-sector portal such as OZG-RE, a national platform such as KSeF, or e-mail where no network applies.
What happens if an invoice is rejected?
The status appears in the portal with the reason in plain language, and can be pushed back to your system. Correct the invoice and send it again – nothing is lost silently.
Can I send to authorities without a Leitweg-ID?
No. B2G invoices in Germany need the routing ID of the receiving body. Invoice-Portal validates it before dispatch and offers a Leitweg-ID database and generator to look it up.
How long does setup take?
Uploading in the portal works the same day. An SFTP or API connection is usually live within a few days; ERP connectors depend on the system and your mapping.
What does sending cost?
The basic package starts at EUR 15 a month with monthly cancellation, and the first 14 days are free. Volume-based and enterprise plans are quoted on your invoice count.
