Custom software engineering

Software that holds up.

Winwise Technologies builds custom platforms, mobile apps and billing systems for companies that can’t afford for them to break. From the first scope to the version still running in year three.

The standard

Anyone can ship a demo. We build the one that survives.

Real users, real load, real edge cases. That is the point where software either holds, or it doesn’t.

What we do

Three things,
done properly.

We’d rather be the team you call for these than a directory of everything. Each one is a practice we staff, not a line on a price list.

Custom software

Platforms your business actually runs on

Internal tools, customer portals, dashboards and the APIs that tie them together. Built around your process — not a template with your logo dropped into it.

  • Web platforms
  • Admin dashboards
  • APIs & integrations
  • Legacy migration
Mobile apps

Apps that ship, pass review, and keep updating

One codebase across Android and iOS where that’s the right call, native where it isn’t. Tested on the phones your customers actually carry, not just the newest one.

  • iOS
  • Android
  • React Native & Flutter
  • Store releases
Fintech & billing

Billing, POS and stock, with the rules built in

Invoicing and point-of-sale for retail, with tax handling, receipts and reconciliation designed in from the first day — not bolted on after the first audit.

  • GST invoicing
  • Point of sale
  • Inventory
  • Multi-branch

One engine

Built once. Tuned for the jewellery counter. the pharmacy shelf. the supermarket till. the hardware yard.

Rate, purity, wastage, making charges and old-gold exchange — the arithmetic a jeweller does in their head, done at the till instead. Batch numbers, expiry dates and schedule categories, checked before the bill prints rather than after the inspection. Thousands of lines, weighed goods and offers that change on a Friday. Speed at the till is the whole product. Sold by length, by weight or by piece. Trade rates, credit ledgers and part deliveries against one order.

Product focus

The jewellery counter, in detail.

Jewellery doesn’t bill like anything else. The price moves with the morning rate, purity changes the maths, and making charges get settled at the counter. Generic invoicing software gets this wrong, so we build it around the counter instead.

Every rule listed here is configurable per branch, because no two showrooms price the same way. Tell us how yours works and that is what gets built.

Concept How a jewellery bill comes together on one screen

Live gold & silver rate

Set the rate once each morning. It applies across every counter and every branch until you change it.

Purity & karat

22K, 18K, 916, silver and platinum — each with its own rate, wastage and rounding rules.

Making charges

Per gram, per piece or percentage. Adjustable at the counter, and printed on the bill exactly as agreed.

Old gold exchange

Weigh it, deduct it, and settle it against the new purchase inside a single invoice.

Hallmark & HUID tags

Barcode tagging tied to stock, so what leaves the tray always matches what leaves the till.

GST invoicing

Correct slabs, e-invoice-ready formats, and an audit trail your accountant will accept without a call.

Multi-branch stock

One ledger across showrooms. Transfers, returns and reorders handled in the same place.

Day close

Cash, card, UPI and advances reconciled at the end of the day. Reports ready before the shutter comes down.

How we work

Four stages. In this order.

Stage 01

Scope

We start with your process, not our stack. A short discovery, written down, and priced before either side commits to anything.

Stage 02

Design

Screens and flows you can click through before they are built. Changes are cheap at this stage and expensive at the next one.

Stage 03

Build

Two-week cycles, each ending in something that runs. You review working software, not a status report about software.

Stage 04

Run

Deployment, monitoring, updates and support. Handover is a stage of the project, not the end of the relationship.

  2. Design
  3. Build
  4. Run

Inside the work

Every part
nobody demos.

Most of a build is the half you never see in a pitch — the migrations, the error states, the reconciliation that has to be right at 2am. That is the half we take seriously.

Working with us

What you get on every project.

No surprises in the scope, the schedule or the invoice. Here is what that means in practice.

  1. 01Same-day answers
  2. 02One team
  3. 03Priced up front
  4. 04Documented
01

Fast answers, not ticket queues

Questions go straight to the engineer working on your system. Nothing waits in a support queue to be triaged first.

Same-day answers
02

One team, start to finish

The engineers who scope your project build it and support it after launch. Your system is never handed to a team that has not seen it.

No handoffs
03

Priced before we start

You get a written scope and a number before any code exists. If the scope moves, we re-price it in the open rather than at the invoice.

Fixed scope, fixed number
04

Documented, and yours

Source, infrastructure and documentation are handed over as standard. Nothing about your system stays locked to us.

No lock-in

Tell us what
you’re building.

A page of notes is enough to start. We’ll come back with scope, a timeline and a price — not a brochure.

What happens next

You send a page of notes.
We ask the questions that matter.
You get a written scope and a price.
Nothing is built before you approve it.
