What is Custom SaaS Product Development?

Building a scalable Software-as-a-Service (SaaS) product requires more than basic CRUD functionality. You need multi-tenant data isolation, self-serve subscription billing, automated invoicing, team seat permissions, and audit logging.

We build production-ready SaaS platforms from scratch with clean TypeScript architectures, Prisma connection pooling, and Stripe webhook handling designed to scale to tens of thousands of active paying subscribers.

Multi-Tenant Data Isolation

Row-level security and organization-scoped database schemas protecting customer data.

Self-Serve Stripe Billing

Tiered pricing, monthly/annual toggles, usage metering, and customer invoice portals.

Team Roles & Invitations

Granular RBAC permissions with automated email team invitations via Resend.

What's Included in Every Project

Full-cycle software engineering deliverables designed for scalability, security, and performance.

Complete System Architecture & ERD

PostgreSQL database entity models, API contracts, and multi-tenant schema specification.

Next.js & React Frontend Dashboard

Responsive web application with dark/light themes, charts, and table pagination.

Stripe Billing & Webhook Engine

Complete subscription lifecycle handling: trials, upgrades, cancellations, and invoice receipts.

NextAuth.js & SSO Authentication

Passwordless magic links, OAuth (Google/GitHub), session management, and RBAC guards.

Automated Cloudflare R2 DB Backups

Scheduled cron jobs taking automated snapshot backups of your production database.
