We ran two POS systems on the same counter for nine days.
A restaurant owner in Surat was paying for established POS software and was not especially unhappy with it. We thought ours was better. There is no honest way to prove that in a demo — a demo is a controlled environment where the salesperson knows every keystroke and nothing is at stake.
So we proposed something else. Run both systems, at the same counter, on the same live bills, for nine days. Every order punched into theirs and into ours. Same staff, same Saturday rush, same confused customer changing their order after the KOT had gone to the kitchen.
What that actually tests
Feature lists are the wrong comparison. Both systems could produce a GST bill. What we wanted to see was the stuff that never appears in a brochure:
- How many taps it takes to punch a modified order when three people are waiting
- Whether the kitchen display actually keeps up, or drifts a few seconds behind and starts causing arguments
- What happens when the internet dips for forty seconds during peak hour
- Whether a cashier who has never seen your software can use it by day three without asking
- Whether the day's totals reconcile against the cash drawer without someone doing sums on paper
Nine days is roughly the point where the novelty wears off and staff stop being careful. That's the useful part. A system that survives careless use survives.
What it cost us
It's an expensive way to sell. Nine days of double-entry is real friction for the client's staff, and every problem in our software was visible to the owner in real time rather than discovered quietly and patched. Twice we fixed things the same evening they were noticed.
But it converts a sales conversation into an operational one. The owner didn't switch because we argued well. He switched because he had watched both systems handle his own counter and formed his own opinion. There was nothing left for us to persuade him about.
Where it stands now
Those figures come from the production database, read on 25 August 2026. We publish them because the nine-day argument only works if the numbers afterwards are checkable too.
The transferable part: if you're being sold software and the seller won't run it in parallel with what you have, ask why. The answer is usually that they're not confident, or that switching is designed to be irreversible. Neither is a good reason to sign.
