First, locate the Business Manager and click into the “Customers” tab on the left side panel. From there, click into the customer you would like to adjust a credit for and click into “Available Credit”
Once you click into “Available Credit”, you will click “Adjust Credit”
You can now see which team member is responsible for giving/using a credit, see the reason a credit was issued or removed, adjust a credit, and the brand new ability to remove a credit altogether.
