My friend is so fed up with his $400-per-month-internet-explorer-based POS, so I wrote him an UWP native app, only $40/month on AWS.

I'm thinking of continuing adding features until it mature enough and release it for free, but charge for cloud usage (if they use the cloud).

Anyone has experience in this? Im gathering info about the "must-have" features for small businesses.

3 months into the job and I got a value recognition award.. woohooo!
