If the charges are already on an invoice, you can void the invoice if no payment was made. This will put the charges back in the billing slider for you to reassign. If a payment was made, then click on the line items and minus them off. Simply close the invoice and go back to the order. Once in the order, you can choose to “change order”. This gives you the ability to keep the original information on the order without having to retype it and it also allows you the ability to make changes. Once you have made the adjustments, assign the fees to the invoice as usual. By doing it this way, the original order stays as is, but the new or changed order is assigned a new order number so you can easily track your steps.
