Drupal Demo Point of Sale Software

One of the latest projects is a fully web based Point of Sale (POS) program that runs from any browser. I developed it using Drupal 7 without using any existing e-commerce or point of sale modules. Currently designed specifically for small businesses and gun stores or outdoor sports dealers. My goal with this software is to keep the features simple and necessary without too much "fluff". The next phase is to consult with some local accountants to ensure it has all of the necessary reports to make corporate tax and other calculations quick and easy.

I would love any feedback or suggestions you could provide, test out the POS software here. I have also started POS demonstration for gun stores at http://bizuns.com/gunstore/
