Build an affiliate system

In this project you need to build an affiliate system so that users will be able to refer our services and get reward/commission. This is a simple work for those who already worked on any affiliate/referral system. Requirement of the project is as follows. 1. Generate affiliate link for each user so that they can promote the link 2. List of referred users under a specific user, for example, John referred 5 users and they joined using guns link, then you need to show earning statistics of these 5 users inside john's affiliate statistics page 3. Affiliate commission of a user from each referred person. 4. When we update an user's account balance (Existing system) in admin panel, then a percentage will be assigned to the person who referred him. Thanks
