Ask HN: What terms are best for a reseller of SaaS?

I have reached out to a startup in hopes of forming some sort of partnership/becoming a reseller. Our initial 90 minute conversation went very well. I would be able to reach markets that they would have difficulty in do, due to various connections I have established as well as barriers of language, culture and geography.The ball is in my court and they have asked that I propose something on how we can collaborate i.e financial structure. What kind of agreement that wouldn't come off as too aggressive that would help us both arrive to a win-win solution. They're priced as a SaaS.
