Edit Order After Invoicing

To edit an invoice AND affect inventory you must delete the invoice (which reopens the order) by going to Billing -> Invoices -> Edit Invoice. Input the invoice number and click 'Next'. Click on the 'Edit' button. Scroll to the bottom and click 'Unpost'.

Then reaccess the invoice again with the above instructions. This time you see a 'Delete' button.

Now you can go to Orders -> Point of Sale and input the order number in the 'Search By Order # Or Customer Name' field, OR go to Orders -> Service Orders -> Edit Order.

Re-invoice the order after making changes.
