The QPB - QuickBooks Point of Sale Data File is a tracking application that is used in the business world. This file application was designed and developed by QuickBooks Point of Sale (POS). POS systems are becoming more and more popular among merchants because of the multiple functions they are capable of performing. The QPB - QuickBooks Point of Sale Data File can be the primary data file or it can be used as a backup file that is automatically created by default through the software.
This file allows business data to be saved, as well as backed up in case of a system failure. QPB files that are backed up use a naming convention in which the year is interpreted in the four character format (i.e. YYYY = 2009, vs. 09) with subsequent entries being in double digits to express both, the most and date.
