Web app & SaaS development, from first login to scale

Full-stack web applications and SaaS platforms — authentication, payments, dashboards, and the infrastructure to scale them.

We build full-stack web applications and SaaS platforms — the products people log into, use daily, and pay for. Authentication, subscription billing, dashboards, admin tooling, and infrastructure that holds up as you grow.

Our bias is strongly MVP-first. Most SaaS products fail not because the idea was wrong but because a year and a large budget went into version one before a single customer touched it. We scope the smallest product that delivers real value, build it properly, launch it, and let real usage decide what comes next.

"Properly" matters, though. Some things can't be deferred if you're charging money on day one: authentication, owner-scoped data access, and real subscription billing. We build those correctly from the start, because retrofitting them is where the expensive rewrites come from.

What you get

Concrete outcomes, not vague promises.

How it works

A clear path from first call to live.

  1. 01

    Define the MVP

    We cut the idea down to the smallest product that proves value and ships.

  2. 02

    Build in cycles

    Short delivery cycles with a live staging environment you can use throughout.

  3. 03

    Secure & bill

    Auth, access control, and subscription billing are built in, not deferred.

  4. 04

    Launch & iterate

    We ship to production and keep iterating on real usage and feedback.

Who it's for

Is this a fit for you?

  • Founders building a SaaS product from scratch
  • Businesses turning an internal tool into a product
  • Teams that outgrew spreadsheets and no-code tools
In detail

What's actually included.

A genuinely scoped MVP

We cut the specification to the single workflow that proves value, and stage everything else. Expect us to argue for removing features — that's the job. A smaller launch gets you real feedback months earlier and costs materially less.

Auth and data isolation done right

Role-based access and owner-scoped data from the first commit, enforced at the database level rather than only in the UI. Data leaking between customer accounts is the one bug a young SaaS rarely recovers from.

Subscription billing that survives edge cases

Razorpay for Indian businesses, Stripe for global. Plans, upgrades, failed payments, webhooks, and invoicing — including the unglamorous failure paths that decide whether your revenue reconciles at month end.

Dashboards and admin tooling

Your team needs to see usage, support customers, and fix problems without a developer running database queries. We build the internal tooling alongside the product rather than treating it as an afterthought.

Infrastructure that scales with you

Server-rendered application, managed database, and deployment that handles growth without a rebuild. We size for where you're going, not for a hypothetical million users you don't have yet.

Context

We run our own products, not just client projects

XYOS builds and operates its own software — BrandSaathi, an AI marketing platform for Indian businesses, and SettledOnSite, credit-control software for UK construction subcontractors. That means we've lived with the parts of SaaS that only show up after launch: billing reconciliation, support load, migrations, and the cost of shortcuts taken early.

For Indian SaaS specifically, that experience covers Razorpay subscriptions, GST-compliant invoicing, and the reality that a large share of your users will first meet your product on a phone.

What it costs

Honest pricing, up front.

SaaS work is quoted after a scoping conversation. As a reference point, a tightly scoped MVP built by a competent team in India typically runs:

TierTypical range (India)What it buys
Focused MVP₹4,00,000 – ₹12,00,000One core workflow, real auth and billing, launched in roughly 6–12 weeks.
Multi-workflow platform₹12,00,000+Several user roles, deeper integrations, richer admin and reporting.

Market ranges for India, not a quote. Scope discipline is the single biggest lever on cost — the tighter the MVP, the lower the end of the range you land on.

FAQ

Questions, answered straight.

Can you build our MVP?

Yes — this is a core focus. We scope a genuine minimum viable product, build it on a stack that can scale, and get it in front of real users quickly rather than over-building version one.

Do you integrate payments and subscriptions?

Yes. We integrate Razorpay for Indian businesses and Stripe for global ones, including subscriptions, invoicing, and webhooks — with the security and edge cases handled properly.

We build our own products too — does that matter?

It helps. XYOS builds and runs its own SaaS products, so we know what it takes to maintain a product over time, not just launch a project and walk away.
