Adjusting Customer Account Balance

Problem

Customer provides incorrect tax registration ID when placing order. Wrong tax zone is assigned to customer account and sales order is created for incorrect sum, due to regular expression for tax registration ID verification has not been set.

Solution

To adjust customer account balance:

1. Assign correct tax zone to customer account before approving order for processing. On approving order for processing, invoice for correct sum will be generated.
2. Create payment for deficient amount and apply it to the invoice.

   Note: Payment gateways can decline payment for sum less than one dollar, or the transaction commission can exceed the payment sum. Thus, if deficient amount is less than one dollar, we recommend that you create a credit memo to adjust customer balance.
