Demo & data notice
What this build is, what it stores, and the things it deliberately does not do. Last updated 12 September 2026.
This is a demonstration of AIMatric Billing. It is not a shop, not a payment terminal, and not connected to any business's books. Every bill, payment, invoice and stock movement it records is simulated and has no legal or financial effect.
The store is a sample
AIMatric SuperMart is a fictional store used to demonstrate the product. Its address, telephone number, GSTIN and FSSAI number are placeholders, chosen so they cannot be mistaken for a registered business's. The GSTIN shown on screen and on printed invoices — 29DEMO0000D1ZD — is not a valid registration and no return is filed against it.
The catalogue is real data, reclassified
The 15,641 items come from a working Indian supermarket's own item list: real product names, brands, barcodes and shelf prices. What the sheet did not carry — the department each item belongs to, its GST slab and its HSN code — is inferred from the product name by a set of keyword rules.
Those inferences are a demonstration of classification, not tax advice. Where the source sheet stated a rate itself, that rate is used in preference to any rule. Everything else is this software's guess, and several of them will be wrong.
Invoices are marked, not issued
The invoice this product prints follows the layout of an Indian tax invoice, including the CGST/SGST split, the HSN summary and a compliant invoice number. It is stamped DEMONSTRATION because that is what it is. It cannot be used to claim input credit, support a return, or evidence a sale.
Payments are simulated
The UPI screen renders a real, well-formed UPI intent QR so the flow can be shown end to end, but it is addressed to a placeholder VPA (aimatricsupermart@demoupi) and no money can move. The “payment received” control marks a bill paid with nothing behind it. Cash tenders update only this demo's own cash book.
Sign-in is deliberately weakened
Staff sign-in has two factors, and the second one — the one-time code — is printed on screen so the product can be demonstrated without a phone in the room. That means anyone who reaches the code screen is through. The demo roster and its shared password are listed on the sign-in page for the same reason. Do not put anything you care about behind this build.
What it stores
- Whatever is typed into it: bills, customer names and phone numbers entered at the till, staff sign-in events and scan history.
- A session cookie, and a theme preference cookie, both first-party.
- Nothing is sent to a third party. Outbound WhatsApp delivery is off in this build; messages are written to the server log instead.
All of it lives in one database file that travels with the demo and is routinely thrown away and rebuilt. Treat anything entered here as disposable, and do not enter a real customer's details.
