What is the difference between a manual refund and a service refund?     

Service Refund -      

When a refund is triggered automatically due to a reduction of a price (reducing the price), applying a Discount or removal of a service/ fee.           

            Example: 

           I paid $50 for my daycare

           I applied a $10 discount

           Grand total becomes $40

           It would trigger a refund of $10 (as I have paid an additionally $10)

     Manual refund     This is when if the business wants to give a refund manually (not triggered automatically).

      This is given, using ``Add Refund`` option (Customer management/ Add refund).
