No, after the initial set-up there are no fees. That means no annual renewal fees, no monthly fees, and no user fees.
The reseller model is based on a revenue share of between 20-30% depending on what level of reseller you choose to become. However, you only pay us once your customer has paid you. So you don't have to worry about monthly payments unless you are already making money!
Not at all, we white label for all our resellers, so that they are selling the product as a part of their offerings, not ours. The only way we're involved is that we get a share of the profits from the reselling.
