The point-of-sale is the most important point-of-contact between the customer and the enterprise. This involves all the economics and management of the business as a whole. An enterprise needs point-of-sale services to differentiate orders and SKUs, calculate costs incurred, and manage your inventory and to print receipts and invoices. On the customer end, point-of-sale services are important for time management, order confirmation and to receive detailed invoices. Point-of-sale services came into the picture in the late 1800s. Punch cards and coupons were the first point-of-sale tools. Then we saw the cash registers which segregated the cash. Then came the electronic cash registers from the brilliant minds at IBM, which introduced the receipt or invoice to the customer and businesses alike. It did not take long for graphical cash registers or the first POS software tools to arrive from there on. At the turn of the century, the POS software were omnipresent as ever.

In the last decade or so, we have seen point-of-sale now arrive in our hands from our computers. Mobile phones and tablets are the new hubs for POS software. AI and biometrics are to take over in the coming decade to revolutionize POS even further. Amazon has taken over the point-of-sale arena from the past decade or so. From ruling the E-commerce globally, now they have entered into automated retail stores, which is what the future looks like being. Amazon is the flag-bearer of point-of-sale in today’s world as it aims to better customer-business contact every passing day. If you won a sales business, these are fascinating times.
