Early last year I decided to build a web based POS solution. A charity I was working with at the time tasked me with finding a affordable POS solution.
The system had to support multiple locations at a reasonable price. Unfortunately I was unable to find any software that fit and so after an initial proof of concept, the project was born.
I aimed at using the latest technologies used in the browser and had fun working with them (localstorage, websockets, etc), as well as some very tricky but gratifying problem solving.
About a year and a half later I feel WallacePOS is ready for source publishing and this week I uploaded it to github under the LGPL.
I hope that it may help businesses like my client have a modern and connected POS system for little cost, and also build a community that can extend and improve the system.
