What does a program actually cost?
Plan price is the smaller half of the bill for most programs. The other half is payout fees and what happens in a month that goes well. The true-cost calculator takes your monthly affiliate revenue and shows the real figure on six platforms, with every price carrying the date it was verified against the vendor's own page.
Who holds your money?
It is the question the pricing pages in this category answer least clearly, and it decides what a payout costs and who carries the risk. The custody page sets out what each platform's own material says, with sources.
Moving a program you already run
Affiliate links your partners published years ago do not have to break when you change platform. AffiliateRail's tracking script reads the referral parameters other platforms use, so those links keep converting to the right affiliate from the day the script goes on. The switch guides cover what the importer brings over and what does not carry.
