SaaS product development
Building a software product means building a business system around it too — tenancy, billing, onboarding and support tooling.
Kolkata and West Bengal
You own the source code
Support after launch
The application is roughly half of a SaaS product. The other half is everything that makes it sellable and operable: separating one customer’s data from another’s, handling trials and upgrades, invoicing reliably, and giving your own team the tools to answer support questions without a developer.
We build both halves, and we settle the tenancy model early — because changing it after launch is one of the most expensive migrations in software.
Problems this solves
Tenancy decided too late
Retrofitting data isolation onto a single-tenant application is a rewrite of the data layer, not a refactor.
Billing that leaks revenue
Proration, failed cards, mid-cycle upgrades and cancellations each lose money quietly when handled by hand.
Onboarding that loses trials
Most trial users decide in the first session. An empty dashboard with no guided path is where conversion goes to die.
Support without visibility
Without an internal admin view, every customer question becomes a database query written by an engineer.
What the work covers
Tenancy architecture
Shared schema, separate schema or separate database, chosen deliberately.
Subscription billing
Plans, trials, proration, dunning and invoices through a payment provider.
Onboarding flows
Sign-up, workspace creation, sample data and a guided first task.
Admin tooling
Internal console for your team to inspect accounts and resolve issues.
Usage metering
Tracking the units you charge for, accurately enough to bill on.
Security and isolation
Tenant scoping enforced at the data layer, not just in the interface.
From idea to a product you can sell
A SaaS build sequence. Multi-tenant design sits third because almost every later decision — billing, security, scaling — depends on it.
Idea
The problem, the buyer and the pricing shape.
Architecture
Services, data model and hosting approach.
Multi-tenant design
How tenants are isolated and scoped.
Development
Core product and admin tooling together.
Billing
Plans, trials, proration and invoicing.
Security
Isolation testing, access control and auditing.
Deployment
Release pipeline, monitoring and support process.
What you end up with
A tenancy model chosen on purpose, early
Billing that handles the awkward cases
Onboarding designed around the first session
Internal tooling so support does not need engineers
Usage data accurate enough to invoice from
Infrastructure that scales per tenant, not per guess
Technologies we commonly use for this
The stack is chosen per project — from your requirements, your existing systems and who will maintain it afterwards. This list is what we reach for most often, not a fixed answer.
Ways to work together
Model A
Fixed scope, fixed price
The scope is written down in detail before work starts, and the price is fixed against it. Changes are quoted separately as they come up.
Best for: Well-understood projects — a website, a defined module, a rebuild.
Model B
Monthly retained team
An agreed number of developer days each month, directed by your priorities. Scope can move without renegotiating a contract.
Best for: Products that will keep evolving after the first release.
Model C
Phased delivery
The system is split into phases that each ship something usable. Every phase is quoted before it begins.
Best for: Large ERP, SaaS and platform builds where the full scope is big.
Model D
Support and maintenance
Ongoing care for a system that already exists — ours or someone else’s — covering fixes, updates and small enhancements.
Best for: Live systems that need a reliable pair of hands.

Frequently asked questions
It is how one running application serves many customers while keeping their data strictly separate. The three common approaches — a shared schema with tenant scoping, a schema per tenant, or a database per tenant — trade off cost, isolation and operational complexity differently.
Through an established payment provider rather than custom billing code. We integrate plans, trials, upgrades, proration and failed payment recovery, and reconcile the provider’s records against your own.
Yes, and it is usually the right approach — provided the tenancy and data model are designed for where the product is going. An MVP should be small in features, not careless in foundations.
You do — the code, the infrastructure accounts and the customer data. We build it; it is your product.
