SaaS applications require multi-tenant architecture (serving multiple customers from one codebase), subscription billing management, usage tracking, team/organization features, and strict data isolation between customers. They also need to be highly reliable and scalable since downtime affects all customers.
I typically integrate Stripe for subscription billing as it handles recurring payments, invoicing, and customer management excellently. I can also integrate Paddle (great for handling taxes globally), LemonSqueezy, or other payment processors based on your needs.
I implement multi-tenancy at the database level with row-level security, ensuring complete data isolation between customers. Each tenant gets their own logical space while sharing infrastructure. This is secure, scalable, and cost-effective.
