We're looking for advice and opinions on economic, effective ways to convert existing users from free to paid subscriptions. Our SaaS product is a slight twist to the traditional freemium model: "buyers" use the system for free and "require" their suppliers to enroll and conduct business with them; "suppliers" use the system (basic) for free, but can upgrade to a premium account for a nominal annual subscription fee. Our market research indicates that "supplier" users want the features available to premium subscribers, and our price is almost an order-of-magnitude lower than the competitors.
Our concern is: how do we quickly, effectively monetize our application? Is outsourcing lead generation an option, and if so, how should we get started with this? What about email campaigns, or webinars?
