POS & Billing Software

If billing a walk-in customer takes longer than the old way, the system is dead by week two — whatever else it can do.

Built with proven, modern technology

What is included

Everything you need. Nothing you do not.

Fast at the counter

Keyboard-first, few clicks, and no screen that waits on the internet before printing.

Pricing that is not a number

Rate-based, weight-based, tiered, or negotiated — modelled properly rather than forced into a fixed price.

GST invoices that file

Correct tax breakup and, where applicable, e-invoicing with IRN and QR at billing time.

Stock that actually moves

A bill reduces stock, a return restores it, and a cancellation unwinds both cleanly.

Built properly

Made to last. Not just launched.

Billing is the busiest place in a shop and the least forgiving. A customer is standing there, a queue is forming, and any friction the software adds is paid for in the owner's patience before it is paid for in anything else. That is why so many retail systems are bought, used for a fortnight and abandoned back to a duplicate book.

Fast at the counter

Keyboard-first, few clicks, and no screen that waits on the internet before printing.

Barcode and thermal printing

With the hardware you already own, not hardware we would prefer you bought.

Cancellation controlled

Who may cancel a printed bill, and what happens to the stock and the tax when they do.

Questions

POS & Billing Software — FAQ

Does it work if the internet drops?
It must. A counter cannot stop because a connection did, so billing continues and anything that needs the internet queues and sends when it returns.
Can it handle jewellery, where price comes from a live rate?
Yes — that is one of the cases we built for. Value is computed from rate, purity and weight at the moment of billing, with the rate recorded on the bill.
Will it replace Tally?
No. It runs the counter and hands Tally clean figures. Rebuilding accounting is expensive and pointless when Tally already does it well.
