Point-of-sale, or POS, refers to the moment a customer purchases your product. A point-of-sale purchase is any transaction. "Point" refers to a location. The point-of-sale is the transaction event itself, while the point of purchase refers to the checkout area.
A point-of-purchase strategy entails finding ways to entice customers to make a higher dollar purchase before the point-of-sale or checkout occurs. Not only does POS financing enable point-of-sale transactions, but it also encourages the customer to spend more.
