i would like to make an online store with a cross platform application on mobiles.
the app will be for a certain city at first and then later on we add more cities and it basically sells very few products (not more than 10 products)
i am looking for a very simple design but the purchasing part must be via sms code confirmation.
for sure i'd also like to make the app automated if the stock is empty -i mean how many items we have in stock- to appear to the customer.
i also would like to have 1 year support if i'd like to change minor things on the application or the graphics, etc...
the app must work on android and ios. making a website is also preferable.
