As SaaS platforms grow, multitenancy presents new hurdles for precise cost attribution, especially with the shift to event-driven, serverless models where resources are shared. With my startup, we built a multitenant SaaS platform on serverless architecture and tackled the challenge of tracking and billing individual tenant usage accurately.

● Understanding Serverless Billing Models
● Cost Attribution Techniques:
○ Per-Tenant Usage Tracking
○ Tagging and Metadata
● Building a Transparent Billing System:
○ Real-Time Cost Monitoring
○ Automated Chargeback Processes
● Overcoming Challenges:
○ Data Isolation and Security
○ Scalability Considerations
● Optimizing for Cost Efficiency:
○ Function Optimization
○ Architectural Best Practices

Attendees will gain practical insights to effectively manage costs in serverless, multitenant SaaS platforms.
