Our Receipt and Invoice are the same document. If you are resending a receipt, then that is the same as "invoicing" the customer as it will show any payments and balance due.
Receipts are NOT automatically sent when an order is changed or updated. A Receipt is only automatically sent if a customer places an order by themselves online. Otherwise, you will need to manually resend a Receipt/Invoice if any update or change is made, such as adding a tonnage charge. Receipts currently serve as an "invoice" in DRS. Future updates will separate these documents.
