Another thing you guys could do is to just disclose a particular "range" of what your terms, pricing and conditions will be at the very beginning so the merchant knows what he's getting into.

With my deals, by the time the guy has sent me an app, he's already "accepted" what the terms, pricing and conditions will be. It's just up to the status of his risk profile on if I can get him approved or not. If I get him approved at the terms, pricing, and conditions we discussed at the beginning, there's usually no objections because he's already been made aware of the pricing at the beginning.
