What Makes SaaS Development Different
SaaS (Software as a Service) applications are fundamentally different from regular websites or apps. They require multi-tenant architecture, subscription management, usage metering, and infrastructure that scales automatically with user growth.
SaaS Architecture We Build
Multi-Tenant Design - Single codebase serving multiple customers (tenants) - Data isolation between tenants for security and compliance - Tenant-specific configurations and customizations - Shared infrastructure for cost efficiency
Authentication & Authorization - SSO (Single Sign-On) with Google, Microsoft, and SAML - Role-based access control (RBAC) with custom permissions - Two-factor authentication (2FA) for security - API key management for developer integrations - Team management with invite and seat-based access
Subscription & Billing - Razorpay/Stripe integration for recurring payments - Free trial management with automated conversion - Usage-based and seat-based pricing models - Invoice generation and payment history - Dunning management for failed payments
API & Integrations - RESTful API with comprehensive documentation - Webhook system for real-time event notifications - OAuth 2.0 for third-party integrations - Rate limiting and API key authentication - SDKs for popular languages (JavaScript, Python)
Analytics & Monitoring - Product analytics with user behaviour tracking - Feature usage metrics for roadmap decisions - Churn prediction and retention analytics - System health monitoring with alerting - Performance dashboards with uptime tracking
