Field notes

What multi-tenant SaaS architecture really requires.

"Multi-tenant" sounds like a tag you add to a database column. In practice it is a series of architectural decisions — data isolation, billing, identity, observability, and rate limiting — that compound across every quarter of the product's life.

Tenant isolation that scales

Row-level security with Postgres RLS for shared-schema tenants, schema-per-tenant only when compliance demands it, and tenant-scoped database connections for noisy-neighbor protection. The wrong call here is the most expensive architectural mistake we routinely unwind.

Billing as a first-class system

Stripe Checkout for the first 100 customers, Stripe Billing once usage-based pricing or enterprise contracts enter the picture. Proration, dunning, and tax are the difference between 5% and 0.5% involuntary churn.

Observability that includes tenants

Every log line, every trace span, every metric should carry a tenant ID. See our SaaS MVP tech stack for the specific tools we standardize on.
