Startup Idea : App for shop owners

Where I live in Africa the shop owners always complain about not having the control of the management of their shops. This is because they give it to other people to manage it and they go once in a while check about the situation of their shop. So, I’m thinking of a smartphone app that will be connected to a website(database) and all the sales will be recorded there in real time. The owner (after authentication of course) will have a dashboard of all the current sales that are taking place from that website.
