Multi-Tenant Enterprise B2B SaaS Platform
A scalable, production-grade B2B SaaS platform architecture. Engineered with PostgreSQL Row Level Security (RLS) for tenant isolation, Stripe metered billing integrations, and self-serve team management.

Identifying the Core Problem
Consulting and service organizations often lack the software infrastructure to convert proprietary manual workflows into scalable subscription products without risking tenant data leakage or billing edge-case failures.
How OXELVO Solved It
OXELVO engineered a production SaaS blueprint built on Next.js App Router and PostgreSQL with kernel-level Row Level Security policies. Features automated customer onboarding, metered usage billing via Stripe webhooks, and an administrative control portal.
Key System Features
- PostgreSQL Row Level Security enforcing tenant isolation at the database layer
- Stripe integration with metered usage tiers, proration, and customer portal
- Team invitation flows with role-based access control (Admin, Member, Viewer)
- Next.js App Router frontend achieving optimal performance benchmarks
- Superadmin analytics dashboard tracking MRR, active users, and tenant usage
