Concept Project (Sample Data Showcase)

Multi-Tenant B2B SaaS Operations & Billing Portal

An architectural foundation concept illustrating how B2B SaaS founders launch securely with clean organization switching, invite flows, plan entitlements, and billing webhooks already structured cleanly.

Problem & Proposed Solution

Bolting multi-tenancy onto an existing single-user codebase late introduces authorization leaks and brittle billing states. A tenant-first foundation enforcing organization context at auth middleware and database query boundaries alongside idempotent subscription webhook synchronization.
