Retail is an Order Type intended for a retail environment. It is similar to quick service but it will allow you to Save and Send before the item is paid for. It will however warn that you are submitting the order without payment and ask you if you want to continue.
When you save and send it will print out a slip which is the request for payment
The intended purpose for this function is so that if a customer forgets their wallet or purse you can send the order, serve another customer and then pull up the order again without having to re-ring all the items.
In order to retrieve a saved order go to Pending Orders > Retail
Edit - Takes you to the Order Screen where you can make changes to the order
