SaaS Development Company in Kolkata

Flint De Orient builds SaaS products from Kolkata for founders and companies turning an idea, a service, or an internal tool into a subscription business. Multi-tenant architecture, subscription billing, roles and permissions, onboarding, and usage analytics — the plumbing every SaaS needs and most first builds get wrong — engineered properly the first time so growth does not force a rewrite.

What we build

MVP Development

01

The smallest version that proves people will pay, built in 10 to 14 weeks with the architecture underneath it ready for what comes next.

Multi-Tenant Architecture

02

Strict tenant isolation, per-tenant configuration and branding, and a data model that stays fast at ten thousand accounts as well as ten.

Subscription & Billing

03

Plans, trials, usage-based metering, proration, dunning, invoices, and GST handling through Stripe, Razorpay, or Paddle — including the failure cases.

Roles, Teams & Permissions

04

Organisations, team invitations, granular role-based access, SSO and SAML for enterprise buyers, and audit logs their security review will ask for.

Onboarding & Product Analytics

05

Self-serve signup, guided activation, and event tracking that shows where trials stall — because activation, not signups, decides whether the product survives.

Scaling & Reliability

06

Caching, queues, background jobs, autoscaling, and observability, so the system holds when a launch or an enterprise customer arrives at once.

The decisions that cost the most to reverse

A SaaS MVP should cut features aggressively. It should not cut architecture. Tenant isolation, the billing data model, and the permission system are the three things that are painful to change once you have paying customers, and they are exactly what gets skipped when a first version is rushed. We build those three correctly from the start and keep the feature set ruthlessly small around them.

  • Tenant isolation designed in, so an enterprise security review does not end the deal
  • A billing model that already understands trials, upgrades, proration, and refunds
  • Permissions as a system, not a scatter of if-statements
  • Every write scoped to a tenant, verified by automated tests
  • Migrations and seed data handled from day one, not improvised later

Built for Indian and global customers at once

Selling to Indian businesses and to overseas customers pulls a product in different directions — different payment rails, different tax treatment, different data-residency expectations. Handling both from the start costs very little; retrofitting either one costs a great deal.

  • Razorpay and UPI for India, Stripe or Paddle for international cards
  • GST-compliant invoices for Indian customers and clean tax handling abroad
  • Multi-currency pricing with per-region plans
  • Data residency options for customers who require them
  • SSO, SAML, and audit logs ready for enterprise procurement

After launch, we run it with you

Shipping a SaaS product is the start of the work, not the end. We stay on as your engineering team through the phase where usage data starts arriving and the roadmap needs to change in response to it — which it always does.

  • Uptime monitoring, error tracking, and on-call response
  • Cost per tenant tracked, so unit economics stay visible as you grow
  • Funnel and activation analytics reviewed with you every month
  • A two-week release cadence rather than occasional large launches
  • Security patching, dependency updates, and penetration-test remediation

FAQ

Questions we get every week

How much does SaaS development cost in Kolkata?

A production-ready MVP with multi-tenancy, billing, and permissions typically runs ₹8–18 lakh. A mature platform with enterprise features, integrations, and analytics runs ₹25–60 lakh. Many clients move to a monthly engineering retainer after launch instead of project pricing.

How long until we can charge our first customer?

A focused MVP with working subscription billing is normally live in 10 to 14 weeks. We build the payment path early rather than last, so you can take real money from real customers as soon as the core feature works.

Do you work with non-technical founders?

Regularly. We handle architecture, hosting, security, and store or platform compliance, and translate it into decisions you can actually make. You get plain-language weekly updates and a working build to click through every two weeks.

Can you take over an existing SaaS codebase?

Yes. We begin with a paid audit covering code quality, security, tenant isolation, and infrastructure cost, then give you a written recommendation and a stabilisation plan before touching anything.

Will it handle payments from India and abroad?

Yes. We typically run Razorpay and UPI for Indian customers alongside Stripe or Paddle for international cards, with GST-compliant invoicing for India, multi-currency plans, and correct tax handling in each region.

Who owns the product and the code?

You do, entirely — repository, infrastructure accounts, and every credential are in your name from day one. There is no licence, no revenue share, and no obligation to keep working with us to keep running your own product.
