The mockup demo · canned data, no uploads

One sample invoice, start to finish.

This is a guided walkthrough on canned data — the real product, shown on a sample invoice. It takes no uploads and sends nothing anywhere; your own numbers stay wherever they are.

The invoice arrives.

A produce invoice lands the way they always do — five lines, one total. This one is the sample the whole demo walks.

Illustrative sample — the demo runs entirely on this canned invoice; it takes no uploads and sends nothing anywhere. Not live or customer data.

Read.

Templates and rules pull the lines — vendor, item, quantity, price. No language model reads the document; a build gate blocks anyone from adding one.

Rules, not a language model — the same invoice in always gives the same numbers out, and your documents never become training data.

Illustrative sample — five lines pulled into fields by templates and rules. Not live or customer data.

File.

Every line lands filed and searchable — by vendor, by item, by date. The whole record exports to a clean CSV whenever you ask.

Illustrative sample — the search shown is part of the mockup, not a live input; the rows are canned. Not live or customer data.

Flag.

The romaine line steps out of its six-month band — up $3.55 a case — and gets the flag. The comparison is against your own history, nothing else.

The line steps out of its six-month band — that’s the flag.

Illustrative sample — the flag fires only against this item’s own six-month band. Not live or customer data.
