The main benefit of Chargebee is having the agility to support an evolving pricing structure. (For the sales-driven model) I had the dynamic pricing already rolled out and working in a day and people buying it in real-time. Similarly, (Self-serve model) I want to retain the seat cost, but increase usage. So Chargebee allowed tiered pricing for different tiers of the product using logic. I also brought in the concept of time-based discounts, which we connected to marketing automation. We're doing all these seamlessly with Chargebee.
