How to create new payment types for sales
You can create any kind of payment by adding to the list located in 'Utilities'/'Drop Down Lists'/'Sales Payment Types'. If you create a payment type called "Store Cash", it will appear in the list on the sales page with all the other payment types. Sales using this payment type will appear on the 1'Shop Takings' reports under "Store Cash".
You can select the date range for takings reports, and they can span any period.
