SaaS Development

Scalable SaaS for Web & Mobile

We design and build multi-tenant SaaS products with perfectly synchronized web and mobile apps — from subscription billing and dashboards to APIs and cloud infrastructure that scales with your growth.

What We Do

SaaS Products Built to Scale

Launching a SaaS product takes more than a website — it needs a secure multi-tenant architecture, recurring billing, and a seamless experience across web and mobile. We build all of it end to end.

From MVP to enterprise-grade platform, we engineer the full stack — responsive web apps, native-quality mobile apps, robust APIs, admin dashboards, and the cloud infrastructure that keeps everything fast and reliable as you grow.

Every product ships with subscription management, role-based access, analytics, and security baked in — so you can focus on customers while we handle the engineering.

FAQ

Frequently Asked Questions

Can you build both web and mobile apps for our SaaS?

Yes, building synchronised web and mobile apps from a single backend is one of our core SaaS competencies. Our architecture uses a single RESTful or GraphQL API that serves both a React or Next.js web application and a Flutter or React Native mobile app — meaning business logic lives in one place, feature parity is maintained without double effort, and your data model evolves once rather than separately for each client. Authentication, permissions, billing, and notifications are all centralised in the backend so users get a consistent experience regardless of device. This approach allowed one logistics SaaS client to onboard 200 enterprise users across both platforms within six weeks of launch, with zero data synchronisation issues. We scope the mobile app requirements alongside the web app from day one to ensure no architectural rework is required later, and the API is designed to support future clients such as smart device or third-party partner integrations.

What does multi-tenant architecture mean?

Multi-tenant architecture means your SaaS platform serves multiple client organisations from a single deployed application, rather than spinning up a separate instance for each customer. Each tenant's data is logically isolated — through row-level tenant scoping in your database, separate schema partitioning, or a hybrid approach — so organisation A can never access organisation B's data, even though both share the same servers and codebase. This dramatically reduces operational overhead: when you onboard a new customer, no new deployment is required; you simply create a new tenant record and provision their account. It also keeps infrastructure costs predictable as your customer base grows. We implement multi-tenancy with careful attention to data isolation security, tenant-specific customisation such as branding and feature flags, and performance isolation so a large tenant's query load does not degrade smaller tenants. We advise on the right isolation model — shared schema, separate schema, or hybrid — based on your compliance requirements and expected data volumes.

Do you handle subscriptions and billing?

Yes, subscription billing and plan management are standard components of every SaaS platform we build. We integrate Stripe Billing as our preferred payment infrastructure, which handles recurring charges, metered billing for usage-based pricing, free trials, upgrade and downgrade flows, proration, coupon codes, and dunning management for failed payments — all without you managing billing logic yourself. We implement a subscription management layer in your application that translates Stripe webhook events into access controls: when a subscription expires, the user's access is automatically restricted; when they upgrade, new features unlock immediately. For Indian payments, we also integrate Razorpay or PayU where UPI, net banking, or domestic card processing is required alongside international card support. Pricing tiers, feature access per plan, and trial-to-paid conversion flows are all configurable through an admin interface so your operations team can adjust offerings without code changes.
