POS
The point of sale (POS) or point of purchase (POP) is the time and place
where a retail transaction is completed. At the point of sale, the merchant
calculates the amount owed by the customer, indicates that amount, may prepare
an invoice for the customer (which may be a cash register printout), and
indicates the options for the customer to make payment. It is also the point at
which a customer makes a payment to the merchant in exchange for goods or after
provision of a service. After receiving payment, the merchant may issue a
receipt for the transaction, which is usually printed but can also be dispensed
with or sent electronically.
The POS serves as the central component for your business; it’s the hub where
everything—like sales, inventory and customer management—merges.
As evident as the benefits of a POS system are, we found that 56 percent of
single-store retailers are still not using one. Instead, we found, many are
still using a combination of manual methods, cash registers, QuickBooks and
Excel for bookkeeping.
So why have retailers not taken that step to POS yet? To begin with,
implementing new technology—especially technology that’s central to your
business process—can be scary and overwhelming. Retailers need to consider the
negative consequences of failing to have a POS in place.
