Yesterday I was clear about this, but now again it seems confusing.
Check Scenario C: Bears Admin 40% | Store 60%
See the item is Rs. 1000
The coupon Cost is Rs. 100 (Rs. 40 beared by Admin and Rs. 60 beared by Store)
So the store is expecting just to bear Rs. 60 to acquire the customer + Commission to Admin (15%)
So, 1000 - 60 = 940
Then, 940 - 15% of 940 = 799
This 799 should be the payout for the Restaurant.
Whatever percentage admin bears, that's all up to them, but Admin should always account the subtotal to calculate the Commission and Coupon bear by Store.
Admin Commission = 15% of (1000 - 60) = 141
Admin Earnings = Admin Commission - Admin Coupon Cost = 141 - 40 = 101
