If you give a customer Store Credit directly to their account; the system will create a Store Credit Adjustment receipt. When you bring that over to QuickBooks through the Link, It add the Store Credit amount to the stores Store Credit obligation amount, and create an equal and opposite adjustment to Store Credit Adjustment. You would then go into QuickBooks and create a General Journal Entry to move the amount in Store Credit Adjustment to the correct Expense Account (eg. Cartridge Cores, Janitorial, ect)
