Return on investment (ROI) in SaaS is tricky, to say the least. Sales cycles are long, customers have multiple visits, and they are exposed to various marketing messages and sales materials - online ads, on-site content, emails, online seminars, etc. When they finally convert it's difficult to calculate Customer acquisition cost (CAC) and you still miss the true Customer lifetime value (CLV) which you will only know after a couple of months.
Dripit is a SaaS itself; we know the pain. That's why we have created the infrastructure which enables you to track inbound marketing and outbound sales in one place. And you can query past journeys when you have figured out which are your high CLV users and want to know how you acquired them.
