# Bill multiple estimates in one invoice

#### When does this application make sense?

Under certain circumstances your customer's purchasing department may only provide one order number for an invoice, but want separate estimate documents for different modules.

#### How to

In an estimate, on the "Billing" tab, you will now find the option (bottom right) to include additional estimates in the final invoice alongside the estimate you currently have open. Click "Add another estimate" here and select another document; this process can be repeated as often as necessary until all estimates are selected.

#### What happens when billing?

When billing, all items and deductions/surcharges as well as any deductions for down-payment or partial invoices that were previously created from the selected estimates are transferred into the invoice. External services linked to these estimates will, if applicable, switch to "billed." Header data and footer notes of that invoice correspond to the estimate from which the billing was initiated (i.e. the one you had open when billing). This means your customer's order number should be entered in the estimate from which you start the billing.

In the first tab and in the "Options" tab under "Estimates for this invoice" such an invoice may now show several documents (and shortcut links), since each estimate document is referenced here.

#### Can such a billing be undone?

If such an invoice is deleted, the status of all estimates billed in it changes from "billed" back to "approval." For external services the status switches back from "billed" to "not billed."

## 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/bill-multiple-estimates-in-one-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.
