# e-Invoice

> Create and manage your invoices

## 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.

<Check>

  </Step>

  <Step title="Enter Routing ID">
    Enter the customer's routing ID (Leitweg-ID). This is required to send the invoice to the public sector client.
  </Step>

  <Step title="Save Settings">
    Save the settings and create the invoice. It will automatically be created in the desired format.

    <Info>
      The invoice is created in the corresponding XML format, but is not digitally sent via Peppol, for example. This feature is planned.
