How to fiscalize bills and invoices for Germany using the Peppol network in Mews Operations

Mews Operations

To meet Germany's e-invoicing requirements, you fiscalize eligible bills and invoices for German business and public-sector customers using the Peppol network in Mews Operations. You do this when you close a bill or issue an invoice for a business-to-business (B2B) or business-to-government (B2G) transaction. This is part of Compliance Suite. Mews automatically fiscalizes and sends each eligible invoice through the Peppol network when you close the bill, so you don't need an external workflow tool. Mews doesn't automatically fiscalize every invoice you issue in Mews, only invoices that meet the B2B or B2G eligibility criteria. You complete this task in Mews Operations as part of your regular billing workflow.

Note
  • Germany's B2B e-invoicing mandate requires businesses with an annual turnover above EUR 800,000 to send structured, Peppol-compatible invoices from January 2027. Businesses below this threshold follow from 2028. These dates apply to the domestic B2B issuing mandate only.
  • For B2G invoicing, structured e-invoices, for example, using XRechnung, have already been mandatory for suppliers to German federal public bodies since November 2020.
  • This feature is part of Compliance Suite, billed at EUR 25 per property per month.

 

In this article, you can learn about:

 

  • Ensure the property is validated on the Peppol network. See How to set up the Peppol fiscal registry integration in Mews Operations.

  • Add the company's VAT ID (USt-IdNr., the German VAT identification number) to the company profile. Mews uses this ID to build the customer's Peppol ID. For B2G invoices, also classify the buyer as a Government entity and add a valid Leitweg-ID to the company profile. Mews uses the Leitweg-ID as the mandatory Buyer Reference (BT-10).

 

Note:

  • If the property has both the XRechnung and Peppol e-invoicing integrations enabled, both work automatically and without conflict. You don't need to disable either integration to fiscalize invoices through the Peppol network.
  • The VAT ID and Peppol ID aren't hard requirements to close a bill or issue an invoice. If the company profile has no VAT ID or Peppol ID, you can still close the bill, but Mews doesn't send the invoice through the Peppol network. See How Mews fiscalizes your invoices for what happens in this case.

 

This automatic flow applies to eligible B2B and B2G invoices. For B2G invoices, the buyer must be classified as a Government entity, and the invoice must include the Leitweg-ID.

  1. Close the bill or issue the invoice as normal in Mews Operations.

  2. If the company profile has a VAT ID or Peppol ID, Mews automatically fiscalizes the invoice and sends it through the Peppol network. You don't need to take any extra action.

  3. If the company profile has no VAT ID and no Peppol ID, Mews shows a dialog titled This invoice will not be submitted to Peppol. Choose one of the following:

    • Cancel: Add the VAT ID or Peppol ID to the company profile, then close the bill or issue the invoice again to send it through the Peppol network as normal.

    • Continue: Mews issues the invoice as normal, but doesn't send it through the Peppol network and doesn't create a fiscal record for it. This is final for that invoice: adding the VAT ID or Peppol ID afterward doesn't send it retroactively.

Note: A VAT ID in the wrong format still blocks you from closing the bill. Mews only shows the dialog above when the VAT ID and Peppol ID are missing entirely, not when one is present but invalid.

 

  1. In Mews Operations, go to the main menu main menu > Finance > Fiscal record report.

fiscal record report 

  1. Review the list of invoices sent through Peppol. The report shows: Number, Created (UTC), Enterprise, Bill, Owner, Peppol ID, Sum, Tax summary, File, Result, Notes, and Status.

  2. Check the Status column for each invoice:

  • Success: The invoice reached both the customer and the property through the Peppol network. You don't need to take any further action.
  • Warning or Error, for example, "party not found in Peppol network": The invoice didn't reach the recipient.
  • No row for the invoice at all: Expected when you closed the bill or issued the invoice without a VAT ID or Peppol ID and chose to continue. Mews doesn't create a fiscal record for that invoice, so its absence from the report isn't an error.

 

If the Status column shows a warning or error:

  1. Download the invoice file from the File column in the Fiscal record report.
  2. Send the invoice to the customer manually, usually by email.
  3. Alternatively, create a credit note and reissue the invoice once you resolve the issue, for example, by adding a missing VAT ID.
