You can record cash rewards through the Credit Card Credit section whenever you receive cashback or a refund for purchases made on your credit card, Lisa.
To start with, it's not advisable to create a random project or expense unless the reward or credit directly relates to that project, as doing so can distort your financial report.
Here’s how you can record it:
- Navigate to the + New button.
- Click on Credit card credit.
- Choose the correct account from the Bank/Credit account drop-down box.
- Under the Category details, select the account that you have for your cash back rewards.
- Fill in the other necessary information.
- Select Save and Close.

If you're unsure about which account to use in the category details, I recommend consulting your accountant to determine the appropriate account.
