# Mark an invoice as uncollectible (write off the balance)

When you've decided you won't collect what's still owed on an invoice, you can write it off by marking it Uncollectible. This is the path for an invoice that has already been sent - including one that has taken a partial payment but won't be paid in full.

You'll find "Mark as Uncollectible" in the "..." menu of the action bar (it appears for a sent invoice that still has an outstanding balance). The dialog asks for a Notes field explaining the write-off, which is required, and it warns clearly that this action cannot be undone.

After confirming, the invoice's status becomes Uncollectible and it shows in red on the page and in your invoice list. Use this rather than Void when money has already been collected, since Void is only for invoices with nothing collected yet.

Because it can't be reversed, double-check the invoice before saving - if you only meant to cancel an unsent invoice with no payments, Void (which can be reopened) is the better choice.

> **Where to find it:** Open a sent invoice that still owes a balance, then use the "..." menu in the top-right action bar and choose "Mark as Uncollectible".

## 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://learn.withessential.com/revenue/invoices/mark-an-invoice-as-uncollectible-write-off-the-balance.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.
