What is the qpb file extension?

A .qpb file is a backup file. It is made by the QuickBooks Point of Sale software. This file is actually a complete backup of your company data. It has all your important information. For example, your inventory, customer details, and all sales records.

Think of it as a safety copy. If your main data file gets corrupted or lost, you can use this .qpb file to restore everything. You will need the QuickBooks POS program to open it and get your data back. It is not like a normal document you can just click and open.
