# Credit Management
You and your team are busy entering in `Invoices` and sometimes a mistake is made where you may have submitted a `Payment Request` and realised something is not right. Perhaps you claimed the incorrect `Support Category`, `Quantity`, `Amount` or something else. That's ok, Maica's Credit Management functionality can fix this up for you easily.
{% hint style="info" %}
The Credit Management functionality allows you to cancel a `Payment Request` that is in the status of Payment Pending or Paid.
{% endhint %}
As part of this process, it is important to note how the NDIS treats the `Payment Request` once it has been cancelled in PRODA:
* If you cancel a `Payment Request` with a `Status` of **Pending Payment**, the `Payment Request` will not be processed.
* If you cancel a `Payment Request` with a `Status` of **Paid**, the Agency may:
* Send you an invoice requesting repayment of the cancelled amount or
* Offset your future payment requests against the cancelled amount
{% hint style="warning" %}
This function is **only available via the API**. If you manage your claiming process via the BPR File, you need to manually cancel the Payment Request in Maica and PRODA.
{% endhint %}
### Let's see it in action
Go to the Invoices tab and select invoice(s) that you wish to cancel its corresponding Payment Request and click **Credit Management:**
Launching the Credit Management Quick Action
A new screen will show with the `Invoice`, `Invoice Line Item` and `Payment Request` to be cancelled. From here, all you need to do is select the desired `Payment Request`, confirm the action is correct and click **Credit**.
On completion, you will see a green tick against the `Payment Request` line and the `Payment Request` `Status` will be updated to **Cancelled** in Salesforce.
Successfully cancelled Payment Request in Credit Management
Payment Request record once it has been successfully Cancelled
You have now successfully cancelled your `Payment Request`!
To recap, if the `Payment Request` had a previous status of **Paid**, you will either receive an invoice from the NDIA, or the amount will be offset against a future `Payment Request`.
