Super cool. We are also doing something similar but not open sourced (still thinking about it). We are doing e-commerce, pos, kitchen-screen etc. Both for product and services so from Yoga Studio/Salons to Take-away Restaurants or ecommerce shops. However focussed only in Europe. Since we are working with a Europe payment processor and early users are getting 0% in transaction fees. The live demo is still not working and we are onboarding on a case by case basis. https://storenu.com
