Webuzo Open Source Point of Sale package has been updated to version 2.3. Open Source Point of Sale is a point of sale system built on top of a CodeIgniter base. It therefore is written in PHP and uses MySQL as the database backend for data storage. This means that it'll run on any system with a web browser and can be run on a local server or hosted for multiple clients to access.
