My product is sold through PayPal. I am commencing a partnership with a website in the same niche. The plan is offering a commission for every person he sends my way who makes a purchase. However, I do not want to have my product on any large affiliate marketplace(my product is within a way too small niche for this). What I am simply looking for is possibly a script or just a website where I can track these sales. I do not wish to pay a fee for every single sale that I make, if a fee should be paid, it should only be on the sales made through the affiliate link. Hope someone can help with a suggestion
