What is an e-Invoice?

An e-invoice is an electronic invoice that is digitally created, sent, and received. It replaces the traditional paper invoice and is usually created in a standardized format such as XRechnung or ZUGFeRD. This enables automated receipt and processing of the invoice, making invoicing more efficient and cost-effective. The e-invoice has been mandatory for German companies to receive since January 1, 2025.

​
Support for e-Invoices

Fynn is fully compatible with the e-invoice standard in Germany and Europe, which means you can create and send e-invoices directly from Fynn in PDF and XML format.

​
Activating e-Invoicing

All invoices, cancellations, and credit notes are automatically created and sent in PDF and XML format (ZUGFeRD) and are thus valid e-invoices.

​
Settings

You have the option to activate the electronic invoice type for the customer. This is particularly relevant for government agencies and public institutions.
By default, the electronic invoice (ZUGFeRD) is activated for the customer.
Here you can select the following options:

Public Sector Clients

To send invoices to public sector clients, for example, you can activate this in the customer settings:
1

Go to a customer and select the corresponding format under “electronic invoice” (XRechnung, for example).
Electronic Invoice
2

Enter Routing ID

Enter the customer’s routing ID (Leitweg-ID). This is required to send the invoice to the public sector client.
3

Save Settings

Save the settings and create the invoice. It will automatically be created in the desired format.
The invoice is created in the corresponding XML format, but is not digitally sent via Peppol, for example. This feature is planned.
