SaaS Platform Development Services
We build SaaS platforms from the ground up — designing multi-tenant architectures, implementing subscription lifecycle management, and delivering scalable infrastructure that grows with your user base. From early-stage MVPs to enterprise platforms serving thousands of customers.
The Challenge
Building a SaaS platform requires solving a unique set of challenges simultaneously: multi-tenant data isolation, subscription billing with trials and grace periods, user authentication across multiple providers, and an architecture that supports rapid feature development without accumulating technical debt. The subscription lifecycle alone — trial periods, payment retries, plan changes, suspensions, cancellations, and grace periods — is a complex state machine that must work flawlessly to protect revenue.
Our Approach
We approach SaaS development with a modular architecture that separates concerns cleanly. Authentication, billing, tenant management, and core business logic each live in their own modules with well-defined interfaces. For Contentrain, our Git-native Headless CMS platform, we built a Vue 3 + NestJS + PostgreSQL stack with 20+ modular NestJS modules. The monorepo architecture (pnpm workspaces + Nx + Turbo) manages multiple applications from a single codebase. Stripe handles subscription and invoice management, while TypeBox provides schema-first API validation. For LineDiff, our AI-powered document comparison platform, we implemented a local-first architecture with IndexedDB as primary storage and Firebase Firestore as a sync queue. This ensures the app works offline while syncing data when connectivity returns. Paddle manages subscriptions, and OpenAI API powers intelligent diff analysis. The platform integrates with Google Docs, Notion, and MS Word as add-ins. For RezMe, we built the complete subscription lifecycle with PayTR integration — handling trial periods, billing cycles, payment retries, suspension, and grace periods. Request-scoped JWT combined with Supabase RLS provides row-level data isolation between tenants.
Technologies We Use
Key Benefits
Battle-tested subscription management — we've integrated Stripe, Paddle, and PayTR across multiple products, handling every edge case from payment failures to plan migrations. Multi-tenant isolation at the data layer, not just the application layer. Local-first architecture options for privacy-sensitive applications. Monorepo architectures that let you ship multiple apps (web, mobile, API, admin panel) from a single codebase. Every SaaS platform we build includes comprehensive authentication (social logins, OTP, device auth), role-based access control, audit logging, and API documentation with Swagger.
