How can I raise a customer invoice credit when using QuickBooks via an android device? Appears to be no option to do so?

Hello there, car-air.

Currently, the feature for Credit memo is not yet available in QBO Mobile. Although, you can do it in a browser. Let me show you the steps below.

Here's how:

1. Click on the + New icon, choose Credit Memo.
2. Select the customer name.
3. Enter the Amount as a positive number.
4. Verify the details in the transaction.
5. Click on Save and Close.

Let me know if you need further assistance. I'd be glad to lend a helping hand. Take care.
