Usage-based pricing models (UBP) offer flexible, consumption-based charges that benefit both companies and clients. Various UBP types include Pay-as-you-Grow, Per-Unit, Tiered, and Hybrid models, each catering to different business and customer needs. Adopting UBP can lead to lower upfront costs for customers, better insights into customer usage for businesses, and opportunities for upselling. The shift towards UBP is gaining momentum, particularly among SaaS companies, indicating a potential standard practice in the future.
