SaaS Development
End-to-end cloud SaaS platform engineering, from multi-tenant database architecture to subscription billing and tenant data isolation.
Overview & Architecture Approach
Devzuno turns software concepts into investor-ready, multi-tenant cloud SaaS platforms. We engineer production-grade SaaS architectures featuring strict tenant data isolation (Row-Level Security), automated subscription billing (Stripe & Razorpay), granular role management, and scalable cloud infrastructure.
Capabilities & Core Deliverables
Multi-Tenant SaaS Architecture
Scalable multi-tenant backend architecture designed to support thousands of subscribing organizations and users cleanly.
Automated Subscription Billing
Seamless integration with Stripe Billing, Razorpay Subscriptions, recurring invoicing, and trial management.
Tenant Data Isolation & RLS Security
Database-level Row-Level Security (RLS) and schema isolation ensuring zero cross-tenant data leakage.
Role-Based Team Management
Granular user permission tiers (Account Owner, Admin, Manager, Member) with secure JWT / OAuth authentication.
Automated Webhooks & API Pipelines
Developer-friendly REST and GraphQL APIs allowing your SaaS customers to build custom third-party integrations.
Auto-Scaling Cloud DevOps
High-availability 99.99% cloud infrastructure containerized with Docker and Kubernetes on AWS or Vercel.
Legacy Builders vs. Devzuno Custom Engineering
| Evaluation Metric | In-House MVP Build (High Overhead) | Devzuno Enterprise SaaS Architecture |
|---|---|---|
| Engineering Timeline | 6 – 12 Months (Slow hiring & build) | 6 – 12 Weeks (Accelerated launch) |
| Upfront Development Cost | High ($40,000 – $100,000+ salary costs) | Optimized (₹1.5 Lakhs – ₹1 Crore+) |
| Tenant Data Isolation | Complex (Risk of cross-tenant data leaks) | Strict Row-Level Security (PostgreSQL RLS) |
| Subscription Billing Engine | Manual billing code (Prone to edge bugs) | Automated Stripe/Razorpay Webhook Engine |
| Cloud Availability | Variable downtime risks | High Availability 99.99% SLA Architecture |
| Source Code & IP Rights | Shared agency ownership | Full Code Ownership or Flexible License |

Frequently Asked Questions — SaaS Development
How much does custom SaaS platform development cost at Devzuno?
Our custom SaaS development packages start from ₹1.5 Lakhs ($1,800) for production-ready SaaS MVPs. Advanced multi-tenant enterprise platforms with custom AI microservices, global multi-region clusters, and enterprise integrations scale up to ₹1 Crore+ ($120,000+).
How long does it take to build and launch a SaaS product?
A production-ready SaaS MVP with subscription billing and user authentication takes 6 to 12 weeks. Complex enterprise SaaS platforms take 12 to 20 weeks.
How do you prevent data leakage between different subscribing tenants?
We implement strict Row-Level Security (RLS) policies in PostgreSQL and separate database schema partitioning. Every database query is automatically scoped with tenant-specific IDs, guaranteeing 100% data isolation.
What subscription payment gateways can be integrated?
We integrate leading global and domestic subscription billing gateways including Stripe Billing, Razorpay Subscriptions, PayPal, and Chargebee, supporting recurring cards, UPI auto-debit, and automated tax invoicing.
Will I own full source code and IP rights for our SaaS platform?
Yes! Upon milestone completion, you receive 100% full source code ownership, private GitHub repository access, database schemas, and intellectual property rights.
