I am new to website designing. I want to create a store for on of my clients. So the thing is he has a very small budget.
So I offered to make a store for him for free and in return I'll take a small percentage of the profit from the sales the store gets for some time. I did this because I need more experience in store building.
Of course I'll only start working for him once I learn about how to do it. So I want to know how do I create the store in such a way that I get that small amount out of the profit. Is there a way to do this or will I have to manually calculate the amount and tell him to pay me that amount every time?
