Point-of-sale system demo: 3 live apps built by AI models
Every app below is a working point-of-sale system, built by an AI coding model from the PlanSmith Retail POS planner. They all run with sample data. Open one, sign in with the demo account it shows, and try it.
Open one and try it.
LiveSaffron Till
The top build, with the cleanest money path on the board. Loyalty reversal on a return is proportional and idempotent in both directions, verified against real data; refunds reverse stored value too; and a second signature is required from someone other than the person acting. A neighbourhood grocery counter in PKR. Click Demo Owner on the sign-in.

LiveCedar & Row
The most self-critical build: its own acceptance panel found a dangerous 'void sale' loop, so the build withdrew the void endpoint outright and routes every correction through Returns, which reverses money, stock and points together and records who approved it. You cannot countersign your own refund. Tap a demo account to fill, then Sign in.

LiveBright Corner
A complete gift & dollar store: twenty operator screens, working loyalty clawback and a real segregation-of-duties check, with the honest 'card blocked, no live provider' notice shown right in the pay dialog. Sign in as owner@brightcorner.local / pos12345 (all demo passwords are on the login screen).
