E-Invoicing at a Glance
From 1 January 2027, invoices for domestic deliveries in Germany and Slovakia are exchanged as structured e-invoices. This page explains what changes for you, which formats and channels we support and how to prepare.
Invoices as XML
An e-invoice is a structured data file (XML) that our systems read and book automatically. A picture of an invoice, such as a scan or a plain PDF, is not an e-invoice.
EN 16931
All supported formats follow the European standard EN 16931. Your invoice software or e-invoicing provider can usually produce one of them.
SMTP, Peppol, SDI
Each country has its own channel. The table in the next section shows the rule for your invoices.
What Changes from 1 January 2027
Three things change for suppliers who invoice a Yanfeng entity in Germany or Slovakia from the same country.
Structured e-invoice
Invoices and credit notes for domestic deliveries must be issued as structured e-invoices in one of the supported formats.
Paper and PDF invoices
Paper invoices and PDF-only invoices are no longer accepted as invoices for these deliveries. In Germany, legal transition rights apply (see below).
New communication channels
Invoices are delivered through the channel of your country instead of PDF by email or post.
Paper and PDF Invoices
For domestic deliveries in Germany and Slovakia, the invoice is the structured data file. A visual copy may still travel with it.
Until 31 December 2026
- PDF by email, read by optical character recognition
- Paper invoices by post, scanned on receipt
- Invoice data read from an image of the document
From 1 January 2027
- Invoice data arrives as XML and is processed automatically
- A ZUGFeRD PDF with embedded XML is accepted
- A PDF without XML, and paper, are not e-invoices
- Credit notes follow the same rules as invoices

Supported Channels
Practical details for each channel. Which channel applies to you is shown in the rules table above.
Germany: SMTP or Peppol
SMTP (email): send the structured file (XML, or ZUGFeRD PDF with embedded XML) to the invoice mailbox of the receiving Yanfeng entity. Please use this mailbox only, not individual employees.
Peppol: you can also send through the Peppol network. If you are registered in the Peppol network, we suggest that you switch to Peppol distribution as early as possible.
Slovakia: Peppol (mandatory)
Send through the Peppol network from your own Peppol access point. Yanfeng receives through its access point.
Italy: SDI
Sistema di Interscambio is the official Italian exchange system for B2B invoices. Submit your FatturaPA invoice through SDI.
Yanfeng Peppol ID
Use the Peppol participant ID of the receiving Yanfeng entity.
You can verify these registrations in the Peppol Directory.
Frequently Asked Questions
Can I still send a PDF?
A ZUGFeRD PDF with embedded XML is accepted. A PDF without XML is not an e-invoice for domestic deliveries in Germany and Slovakia. In Germany, the legal transition rights described above apply.
Do credit notes also have to be e-invoices?
Yes. Credit notes and corrections follow the same rules as invoices. XRechnung and Peppol BIS Billing credit note formats are supported, and ZUGFeRD can carry credit notes.
What happens if my e-invoice is rejected?
Your e-invoice is validated on receipt. If it does not meet the format or content rules, you receive an error report and send a corrected e-invoice. Where price or VAT changes, please send a credit note and a new invoice.
I am located outside Germany and Slovakia. Does anything change for me?
No. Cross-border invoices to our German and Slovak entities continue as agreed with your Yanfeng contact. This may change when the rules of your country change.
Where do I find the Yanfeng Peppol ID?
The Peppol participant IDs for Germany and Slovakia are listed in the sections Supported Formats and Supported Channels, and can be verified in the Peppol Directory. Several Yanfeng addresses share one participant ID, so please also quote your purchase order on the invoice.
