Hello! I purchase from multiple vendors, and have different profit margins on each product and category of products. I can't offer affiliates a static percentage as it would be too much for some products and too little for others.

Commission on PROFIT instead of SALE PRICE. Ideally, I’d like to have a field per product which was the actual cost of the product (obviously hidden from users). Then I’d like to be able to offer a flat percentage commission based on the profit of each sale or product. For instance, I enter my COST is $25 and my sale price is $45. I have an agreement to pay 20% of profit, so I would owe the affiliate $4 (20 x .20).

Alternatively, I could likely get away with setting commission rates by CATEGORY instead of just a flat rate.

Is it possible to do anything like this? Possible with HikaMarket in conjunction with HikaShop? Possibly with 3rd Party Software integrated with HikaShop?

Thanks in advance.
