Trying to get back to a work order from an invoice ?
After creating a work order and completing the work in service and maintenance, I have then created a customer order to generate an customer invoice. The invoice is then sent to the customer to check and pay, however if the customer has a query and gets back to the business, at the moment there is nothing on the invoice that references to the work order that was completed. How does the business establish what work order the invoice is for?
Thanks
