1. Designing Multi-Tenant Databases
SaaS applications must isolate customer data securely. Relational databases like PostgreSQL support row-level security (RLS) policies, ensuring a user only reads records belonging to their tenant account.
2. Structuring Billing Workflows
Integrate flexible payment engines like Stripe early. Set up hooks to sync subscription statuses, handle annual/monthly plans, update tiers, and process payment failures without lockups.
3. Building for Frontend Speed
SaaS dashboards handle heavy data reads. Building in component-driven React with smart state management keeps page updates fast, improving user retention.
