We sell food items to restaurants. We work with approximately 80 restaurants and growing. We are looking to set up a b2b site where these 80 restaurants can enter our site and produce their own purchase orders. This site needs to be locked and view-able only by the 80 customers whom we will create a username and password for. In other words, no other restaurants or competitors can enter our site and view our catalog. Since these will be treated as purchase orders, all items will not have any prices. We need an expert to create the engine and we will perform all the data entry ourselves and add our products etc. You will not spend much time creating an impressive design since the design will be basic. Remember this will attend to b2b only. Nobody can create an account, we will be responsible for creating accounts and providing our restaurants with their username and login credentials. Restaurants cannot edit any of their details online, only we can edit their details.
