How to create a software subscription/tenant management solution with AWS
Introduction
The subscription-based SaaS model has become the standard for modern digital products. However, the technical complexity behind managing multiple tenants, differentiated tiers, billing automation, and financial integration is often underestimated.
This whitepaper presents an architectural approach for building a subscription and tenant management solution on AWS serverless services, using Rootstack's Rootlenses implementation as a real-world example.
The proposed architecture uses AWS Lambda as the core of the business logic and Amazon EventBridge for the scheduled automation of critical processes such as billing and subscription status validation.

The result is a platform that is:
- Highly scalable
- Cost-optimized
- Automated in financial processes
- Designed for multi-tenant environments
- Integrable with ERP systems
This document is intended for organizations looking to modernize their SaaS model and leverage AWS capabilities combined with Rootstack's expertise in cloud architecture and enterprise development.
