How it works
Upload the contract; confirm each line it proposes, every one carrying the quote it came from.
Orders, cartons, pallets, returns — each figure marked with where it came from.
The engine prices the month, compares it line by line, and says how much it could verify.
A letter with the clause and the arithmetic inside, sent from your own inbox.
The deliverable
No product name, no jargon. Written for someone in accounts receivable who has never heard of us — and it closes by asking them to correct us if the figures are wrong.
Not a mock-upThe letter below is generated by the product. This is the screen it is generated on:

Claim for billing correction
We have compared this invoice against our agreement and our records of the work performed. We believe 1 charge was billed incorrectly, totalling $36.00.
What we believe happened: the volume tiers in our agreement were not applied.
Receiving — $1.25/carton to 200,
$0.95/carton thereafter
CARTONS_RECEIVED 320
If our figures are wrong, please tell us where.
Why trust it
A model proposes what your contract says. Not one cent is computed by one.
A finding resting on a typed number is marked unverified, on screen, before you send it.
Undercharges are shown but never claimed. Asking would be asking to be invoiced.
The figures are being set with the first customers, who get founding terms.
You are buying spend predictability; a price you cannot forecast would contradict the product on its own invoice.
