Create a Product Delivery App with built in features

I would like to create an app that allows
-customers to browse my available products (hoodies, flowers, candy, etc)
-create a user profile to store preferences, and set up recurring orders
-order products for delivery or in person pickup, track for updates as well
-create a inventory tracking system

(Pos, crm, delivery, inventory mgmt)

Please be prepared to show past examples of work if possible.
