This project is a loyalty program that was developed for Goshnamooneh icecream branch to manage customers and give a way credit to encourage users to revisit the store and buy again. In this panel, every customer can get credit with buying products from the icecream branch or application. A customer might also introduce another customer in exchange for credit. each customer can save credit to a fixed amount and should use his/her credit in a month. After each user is registered in the system an SMS will notify them and helps them with the instructions. Also whenever the credit of a user changes(adds a credit or uses credit), the system will notify him/her with an SMS.
