In Symbient Opta, you can create an Invoice directly from the Customer Order.
After having created and saved a Customer Order with Items, select the Customer Order that you would
like to invoice by clicking on Accounting>Accounts Receivable>Customer Orders from the left-side menu,
and from the list of orders:
Click on the Pencil icon
Check the box and click Edit
Click the Customer Order Number link
On the Details tab of your Customer Order, click the Create Invoice button.
Symbient Opta will automatically open the Create Customer Invoice screen and copy the date from the Customer Order to the Invoice.
