Multi-tenancy + RLS
The Problem
Off-the-shelf ERPs are expensive, rigid, and owned by someone else
Enterprise software vendors charge for every seat, every module, every customization. When your workflow does not fit their template, you adapt your workflow — not their software. Maintenance windows are their schedule, not yours. And when they are acquired or discontinued, you start over.
Our Approach
Purpose-built platform for your exact workflow. You own everything.
- ◆Full multi-tenant architecture from day one — isolated schemas per client with PostgreSQL RLS
- ◆Next.js frontend — fast, SEO-ready, mobile-first, TypeScript throughout
- ◆FastAPI backend — typed API, async-first, production-grade from day one
- ◆Clerk auth — SSO, MFA, RBAC, all configured and ready
- ◆Stripe billing — subscription management, usage-based billing, invoice generation
- ◆Docker + Pulumi — infrastructure as code, reproducible deployments, no manual server config
- ◆Proven reference: iKargos CHA platform — replaced a legacy ERP — 1000+ corporate clients
