POS and GST billing software for retail

Bill in seconds even when the internet drops. Every sale updates stock, loyalty and reports across all your stores automatically.

What is POS software?

POS (point of sale) software records sales at the counter: scanning items, applying prices and discounts, generating GST invoices and accepting payments by cash, card or UPI. Modern POS systems also update inventory, manage loyalty programmes and report sales across stores.

What our pos and billing software covers

Fast GST billing for retail counters with inventory, loyalty and multi store reporting.

Fast billing

Barcode scanning, quick keys and hold bills.

GST invoices

Thermal and A4 formats with HSN codes.

Payments

Cash, card, UPI QR and split payments.

Loyalty

Points, coupons and customer history.

Offline mode

Billing continues without internet.

Multi store

Central pricing, transfers and reports.

How we approach pos and billing software

Queues lose customers. We optimise the billing screen for speed with keyboard and scanner shortcuts.

Offline mode keeps billing running during outages and syncs when connectivity returns.

Every project starts with a short discovery call and ends with software you own: source code, data, cloud accounts and documentation are handed over in your name.

From first call to launch

The same five stages for every build, with a working demo at the end of each sprint so you see progress, not promises.

  2. Design

    Clickable prototypes of the key screens, reviewed with the people who will use them every day.

  3. Build in sprints

    Two week sprints with a demo each time. You can change priorities between sprints.

  4. Test and launch

    Functional, security and load testing, data migration, training and a planned go live.

  5. Support and grow

    Monitoring, fixes and new features on a monthly plan, or a clean handover to your team.
