IT and SaaS App Development

At Ahex Technologies, we can build a basic SaaS product with subscription billing for $35,000 to $80,000, or ₹12L–₹28L. For a multi-tenant SaaS platform with SSO, advanced user roles, subscription management, and third-party integrations, we charge costs of around $80,000 to $250,000. In INR, that would be ₹28L to ₹85L. For large enterprise SaaS platforms development, the development costs can range from $250,000 to $700,000+ or ₹85L to ₹2.5Cr+.

Multi-tenant architecture allows one SaaS app to serve multiple customers. Meanwhile, each customer’s data is kept separately and secured. This means every customer gets their own login experience while sharing the same core infrastructure, which helps reduce hosting and maintenance costs. At Ahex Technologies, we implement multi-tenancy using row-level security (PostgreSQL RLS) for most platforms, or schema-per-tenant for regulated industries requiring stronger data isolation. We design the tenancy model in Discovery before any development begins.

Yes, increasingly, SSO is a hard requirement in enterprise procurement. IT departments cannot manage separate credentials for every SaaS tool. They need to provision and deprovision access through their central identity provider (Okta, Azure AD). Without SSO, your SaaS product doesn’t get past the IT security review. Adding SSO later means retrofitting into authentication that wasn’t designed for it. We build SSO-ready auth from the start, and add specific IdP configurations later.

No. Adding multi-tenancy later to a single-tenant SaaS platform is not a good idea. The process can be very time-consuming and expensive as well. It requires making major changes to the platform’s database, APIs, and app logic. Then, the complete SaaS platform must be tested to prevent any sort of data leaks between customers. All of this can take 3 to 6 months. However, we build multi-tenancy from the very beginning and avoid all these. 

We implement Stripe Billing or Chargebee as the billing engine. This handles plan management, recurring charges, proration on mid-cycle plan changes, trial periods, failed payment retry (dunning), and a self-service billing portal. Stripe webhook events notify our backend to update subscription status in real time. The feature access is gated by subscription status at the API level. For iOS apps, Apple’s guidelines may require StoreKit 2 for some billing flows. We assess this in Discovery and design the right approach.

Yes, white-label SaaS is a significant part of our SaaS app development services. White-label architecture includes tenant-level branding configuration (logo, colours, custom domain, branded email templates), a partner admin console for managing sub-tenants without engineering involvement, isolated data and billing per partner, and an onboarding flow that deploys a branded environment in minutes. We also build the commercial layer, which includes partner billing, commission tracking, and reseller reporting, for SaaS products with channel sales programmes
