Pay-As-You-Go (PAYG) for SAP BTP is ideal for customers who want to minimize upfront investment. It allows for incremental consumption of SAP BTP services, ensuring costs are only incurred based on actual usage. This model provides the flexibility to transition to subscription-based plans if the proof-of-concept is successful, without losing the existing investments. It enables scalability, making it suitable for experimenting with innovative solutions while maintaining a low financial risk.(Reference: SAP BTP Pricing Plans)
