Step 2: Open Payment Method Settings

To handle instant rebates correctly, you must create and use a dedicated payment method called Instant Rebate.

Go to your POS Settings menu.

In Settings, search for Payment Method.

Open the Payment Method configuration section.

Create a new payment method.

Name this payment method Instant Rebate (or a clear equivalent).

You should now see the newly created Instant Rebate payment method listed.

Confirm that the Instant Rebate payment method is active and available for use.
