What if @Saurabh make a module which allow store owners to deliver their own orders?
Let me explain... With this module Admin can choose if a store will manage all deliveries himself or Admin will manage deliveries.
Obviously, if store owner will manage deliveries than his commission will be less than usual commission set by Admin. Benefit for store is that they get a platform to get order online and admin get commission. This is also useful in areas where Admin can't deliver because he dont have delivery boys in that area (outside the city or nearby small towns).
Just Eat is doing same thing in Europe. Many restaurants in my area are using just eats platform to get online order. Restaurants use JustEats app to get order and than manage deliveries by themself because Just Eat doesn't have any delivery boy in our area.
Obviously, instead of paying commission, I chosen my own platform instead using JustEat and started using Foodomaa. If there is option to allow store owners to manage deliveries by themself than I will consider about adding more stores to my app.
