# Edit the payment details on a supplier invoice

To edit or update a customer invoice: 

* Go to Expense --> Supplier Invoices. 
* Click on the drop-down button of the draft invoice you need to update from the list.  
* Select Edit and make changes. Click on Update. 

Note: You cannot directly edit an invoice which is already sent to the supplier. In order to update the details of a sent invoice, you must change the status of the invoice to draft first and then follow the steps which are given above.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.simpleaccounts.io/product-guides/expense/supplier-invoices/edit-the-payment-details-on-a-supplier-invoice.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
