SaaS Architecture

SaaS MVP ArchitectureBuilt for Scale

Building a SaaS product requires more than just code. We architect multi-tenant systems with proper data isolation, subscription billing, and infrastructure that scales from your first customer to your ten-thousandth.

Multi-Tenancy

Data Isolation Done Right

Frequently Asked Questions

How do you handle multi-tenancy?

We use database-level row security with tenant ID on every table. This ensures complete data isolation without the complexity of separate databases per tenant.

What billing provider do you integrate with?

We primarily use Stripe for its reliability and feature set. We can also integrate with Paddle for SaaS businesses needing merchant of record services.

Can users belong to multiple organizations?

Yes, we design the data model to support users being members of multiple organizations with different roles in each.

How do you handle enterprise features like SSO?

We build with SSO/SAML in mind from day one. Even if you don't need it immediately, the architecture is ready when enterprise customers require it.
