# E-invoice

The outgoing invoices of Die Agenturverwaltung already support the ZUGFeRD 2.1 standard as a hybrid e-invoice.

This means that the invoice is readable as a PDF for humans, but an XML file is embedded in the PDF that is machine-readable and provides the invoice content as structured data.

With Adobe Acrobat Reader DC this XML file (faktur-x.xml) can also be opened. It can be found on the left under the Attachments tab with the paperclip icon.

E-invoices can also be received with Die Agenturverwaltung.

## Sending e-invoices by e-mail

The dispatch is by default in the format **PDF/A-3** as a hybrid e-invoice with embedded XML in the format **ZUGFeRD 2.1**.

However, other formats than **XML** or **JSON** (or even just as **simple PDF** without embedded e-invoice) can be sent by e-mail:

{% embed url="<https://www.loom.com/share/0c9b427f681b428c922fa4c1f756e1f1>" %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.dieagenturverwaltung.de/die-agenturverwaltung-en/finanzen-1/ausgangsrechnungen/e-invoice.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
