# Create advance invoice
Die Agenturverwaltung offers the possibility to create downpayment invoices directly from an estimate.
## What is a downpayment invoice?
Downpayment invoices are invoices for a customer's partial payment on a service to be provided. They refer to an estimate in which the service is defined.
For larger estimates they should be a binding part of the offer; it is sufficient to place a note in the footer of the estimate such as "We charge 50% of the quoted amount upon approval".

**Downpayment invoices offer many advantages**
a) They obligate the customer; by making an initial partial payment due, the offer is formally indisputably commissioned
b) They are important for maintaining your company's liquidity
c) They protect your company and, if applicable, your suppliers from a total loss if your customer, for example, has to file for insolvency during the project.
{% endhint %}
In the "Billing" tab of the estimate I can see whether invoices have already been issued from this estimate.
## How to create a downpayment invoice from an estimate
In the "Billing" tab of your estimate select a billing method:
Choose either a percentage downpayment invoice - e.g. 50% of the quoted amount - or a flat amount - e.g. 2000 EUR:
Then, if applicable, enter the desired invoice date and — if different from the estimate — the job, and click "Create invoice now".
The downpayment invoice will then be created.\
If you now return to the estimate, the "Billing" tab shows that a portion has already been billed in the form of a downpayment invoice:

## 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/kva/abrechnung-von-kostenvoranschlaegen/akonto-rechnung-erstellen.md?ask=&goal=
```
`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.
