Ask HN: Help me finish this Point of Sale?

I have been kicking around different approaches for doing a web based point of sale and have made a few different variations that I have been testing in a bicycle shop that I co-own. The latest iteration is built on Rails w/ bootstrap.

Besides working the bicycle shop, I also have a full time job as a web developer and with both of these I haven't been able to pay any attention to the latest iteration of the point of sale. I had initially planned to develop it into a SaaS style offering but due to my lack of time, I have decided to open source what I have so far. Perhaps someone would be interested in improving and finishing it.
