The Invoice Type Window in the Point of Sale program is used to specify the type of POS invoice or transaction being processed. The Point of Sale program allows you to process SALE and RETURN transactions. The POS invoice type to be created will default to SALE and the invoice type can be changed when required by using the prompt button that is located on the right side of the Type window. You should select the correct Invoice Type before entering the line item detail for the new invoice.
