CORE-POS is the point of sale oriented project under Co-operative Operational Retail Environment (CORE). The code is based heavily on IS4C with a focus on greater modularity and collaboration.

CORE is primarily a web-based, PHP+MySQL application. There are a few C# pieces most of which are Mono-compatible.

The master branch is not intended to be completely stable. Non-developer users would be best served tracking one of the version branches.

Quick Start

  • Install PHP, MySQL, and a webserver
  • git clone --depth 1
  • If desired, checkout the lastest version branch instead of master.
  • Run composer install.
  • Browse to fannie/install/ to set up the back end.
  • Browse to pos/is4c-nf/install/ to set up the lane.



Feel free to open an issue relating to any subject - development, usage, or otherwise. Be aware that:

  • Developer questions pertaining to older versions may be answered with "Please upgrade to the latest release first"
  • Issues that haven't had any response in 30+ days may be closed and tagged Closed Pending Feedback. Re-opening these issues is to provide feedback is fine.
