# Pagination numbers for purchase invoices

### **Best practice at Die Agenturverwaltung** Pagination numbers for external services or purchase invoices

Die Agenturverwaltung assigns a pagination number to each recorded purchase invoice. Many agencies also note this number on the paper document when the invoice is received (if there is one).

This way the paper document also indicates that it has already been recorded in the system.

The pattern for pagination numbers is as follows: \<four-digit year>-\<four-digit sequential number>

> 2022-0009

Marking digital documents is not necessary in the agency software, since they are uploaded directly to Die Agenturverwaltung and can be accessed at any time.

These documents can also be forwarded digitally to the tax advisor in the form of links.

## 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/onboarding/nummernsysteme/paginiernummern-fuer-eingangsrechnungen.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.
