1. Receive
A PDF, JPEG or PNG arrives by private upload or a rotatable site forwarding address.
How it works
A reviewed path from invoice to action.
PriceGrid keeps operator records private, makes uncertainty visible and publishes a peer signal only after its safety rules are met.
Walk through the synthetic demo2. Protect
The file is validated, deduplicated and scanned before any extraction begins.
3. Extract
Invoice fields and lines become candidates, with confidence and raw values retained.
4. Review
An operator approves, rejects or escalates every uncertain item. Only approved lines publish.
5. Aggregate
One latest eligible observation per site contributes. Small cohorts remain fully suppressed.
6. Act
An alert appears only when movement is material and your latest price is above P75.
