I recently read some answers to the question of What terms re-sellers use for selling SaaS? In one of them someone suggested to create other revenue opportunities for de resellers other than commissions to increase the revenue. I was thinking what kind of services could they provide to the customers besides onboard new clients or first line support?
It does depend on what niche the SaaS is serving, one option is to go the affiliate sales route and provide joint venture partners with the popular opportunity of winning contests with cash or prize payouts. You can contact me for my experience of this strategy if that would be helpful.
