# Is invoice required for reimbursement?

Yes.
An **invoice is required** for reimbursement.

### How this works
* An invoice must be submitted as part of the **proof of action**
* The invoice should:
    * relate to the booked campaign
    * match the submitted campaign and expense details
* Reimbursement review cannot proceed without a valid invoice

### Important to know
* Invoice must be included even if other proof is provided
* Missing invoices may result in **Info requested** or **rejection**
* Invoices should be clear and readable
* Invoice submission follows the same proof upload rules
