POSperfect is the POS and Branch Back Office system. It is written in Delphi and the latest versions use a Firebird database through the InterBase Objects (IBO) Database engine.
The principle design criteria was that "The POS Terminals must not depend on a Server or Network to process sales" and that "Online/Offline transitions must be seamless".
The system maintains a mission critical database on every terminal so that the POS functions are not Server dependent. This allows the POS terminal to function when a network or Server is down which eliminates the need and cost of a Backup Server to achieve redundancy. In addition this design divorces the POS processing functions from any network or Server bottlenecks so that a major processing task on the Server does not impact on standard sales processing. The background network management processes in POSperfect handle any offline/online conditions seamlessly.
The Server or Master terminal for each store maintains an up-to-the-minute detailed stock and sales history of every stock item movement and every transaction. In addition, the database automatically consolidates individual product history into group history for up to 4 hierarchical groups (e.g. Department/Class), plus Vendor consolidation and up to 4 horizontal user definable groups e.g. Label, Brand, Pack Type, etc. The system also supports SKU/PLU, SKU/Barcode and SKU/Size/Colour (matrix) merchandise types.
