I am looking to develop multi-store application in the platform of Android and IOS along with web site. All got to be on the same date base. Customer and supplier got to have an access with search capabilities. Customer and supplier got to be notified by email or phone notification with new subscripted categories or specific product. Supplier should have option to bid on customer requests and customer shall be able to accept. All transactions shall be logged and tracked with unique number for tracking purposes.
