Selling your Saas through partners is a good business model - if you do it right. There's a good potential to scale your business with the right partners, also internationally.
The key is to understand who is your potential partner and how to qualify with whom to work with. Lot's of boxes to tick, from target customer focus to C-level commitment and joint business planning.
Throughout the years, I've witnessed many stories, where the company signs a reseller agreement(s) with a partner, who is not a good fit. This usually ends up with no business, waste of time, money, and resources, and a lot of frustration.
Do your homework, research the market, prepare a solid plan, but most of all, define your sales strategy and team so that it reflects the customer buying process, and… use local sales professionals, with the right contacts and market knowledge.
Hiring an outsourced sales team and then ignoring them is probably not the best idea.
Bad investments have bad ROI.
