# X-invoice, e-invoice, ZUGFeRD ...

The invoices of Die Agenturverwaltung already support the standard ZUGFeRD 2.4 as a hybrid e-invoice.

This means that the invoice is readable as a PDF by people, but it also contains an embedded XML file in the PDF, which is machine-readable and provides the invoice content in structured data.

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

E-invoices can also be received with Die Agenturverwaltung.

## Sending e-invoices by email

By default, sending takes place in the format **PDF/A-3** as a hybrid e-invoice with embedded XML in the format **ZUGFeRD 2.4**.

However, other formats can also be sent as **XML** or **JSON** (or even just as **plain PDF** without an embedded e-invoice) by email:

## 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/x-invoice-e-invoice-zugferd-....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.
