Billsby

Billsby is a wildly explosive, fiercely developer-centric disruptor that mathematically attacked the "Complex Pricing Model" bottleneck for growing SaaS companies. It engineered a beautifully intuitive, yet terrifyingly powerful billing engine. It is the absolute weapon of choice for product managers who mathematically demand to implement a highly complex, 5-tiered usage-based pricing plan with feature tags and allowances in under 10 minutes.
