The job this tool does, and who does it today
Trade schemes are how manufacturers and distributors move volume through a channel they do not control. A slab structure is announced, dealers order against it, and at the end of the period somebody has to work out what each dealer earned.
That somebody is almost always a commercial executive or an area sales manager with a workbook. They pull a dispatch report, paste it into a tab, subtract returns if they remember to, apply a slab table typed by hand, check outstanding balances against a separate ledger, and produce a payout list. Dealers who disagree are told the number was checked. Dealers who ask where they stood in week six were told to wait for the quarter to close.
The tool's job is twofold: produce a payout that finance and the dealer both accept, and make achievement visible while the scheme can still influence ordering.
