Hi warriors i currently use a third party suppler for the back-end of a dating site
i run were i have a revenue spiting agreement

I would like to recruit my own affiliates but as the billing and sale is made on there server i would like some advice

they are willing to use any tracking pixels i provide

so the question is are there any out the box solutions for WordPress that would allow me to run my program and track the sales that are made on there external server ?
thank you in advance
