The point-of-sale, or POS, and inventory tracking systems for hospitality organizations integrate with the other information systems such as accounting and operations information systems. The accuracy of information input at the POS is critical because that information is passed on to other systems and databases. The information input into the POS can be from multiple transactions inputs. These inputs can be from booking transactions, sales transactions, service transactions, prepay transactions, after-departure transactions, as well as any other transactions.
