PRODUCT ENGINEERING

Software you own outright.

From a blank repository to a product in production.

We build the software a business runs on: the dashboard the team lives in, the portal customers log into, the app that goes on a phone. Not a page builder with a login bolted on — a real product, with real state, that holds up when the traffic arrives.

We ship our own SaaS as well as yours. BizGST Pro is live and has paying subscribers, which means the decisions on your build come from having operated software, not just delivered it.

WHAT YOU GET

Everything below is delivered.

Not a menu of things we could look into. Each one is scoped, priced and handed over.

01

SaaS platforms

Multi-tenant products with accounts, roles, billing and an admin that your team can actually run without calling us. Built to be handed over.

02

Dashboards & internal tools

The screen your operations team stares at all day. Fast filters, real exports, and numbers that reconcile — because a dashboard nobody trusts gets replaced by a spreadsheet.

03

Web apps & portals

Customer logins, document upload, status tracking, payment. The things that otherwise live in a WhatsApp thread and get lost.

04

Installable apps

Apps that install to the home screen from a link and work offline, without a Play Store review sitting between you and your customers.

05

Integrations

Payments, GST e-invoicing, accounting, logistics, WhatsApp. Wired into what you already use rather than replacing it.

06

Technical SEO & performance

Rendered on the server, measured on real Core Web Vitals. Fast is a feature, and on a marketing site it is the feature.

HOW IT RUNS

Four steps, no mystery.

01

Scope

We write down what it does and what it does not do, and price it. That number goes in writing before anyone opens an editor.

02

Build

Deployed from day one, so you are looking at the real thing on a real URL rather than at a picture of it.

03

Handover

Repository, deployment, environment variables and a written runbook. You could take it to another studio the next morning.

04

Aftercare

The same people who built it fix it. No account manager in between.

QUESTIONS

Before you write to us.

Yes, outright, and the repository is transferred to your account at handover. There is no licence, no per-seat fee and no platform of ours you have to keep paying for to keep your own software running.

A marketing site starts in the low tens of thousands of rupees. A web app or SaaS build is quoted per scope once we understand it. The number is fixed in writing before work starts and does not move unless you change the scope — in which case you approve the change first.

A marketing site is 48 hours from an agreed brief. A working product is scoped and time-locked after we understand it — usually weeks, not months, because we cut scope rather than deadlines.

Next.js and React, TypeScript throughout, Postgres, deployed on Vercel unless you need it somewhere else. Boring, widely known choices — so the next engineer who touches it is not learning something we invented.

START SOMETHING

Tell us what you're building.

A short note is enough. We'll come back with what it would take, what it would cost and whether we're the right people for it.
