Trade deduction validation

Trade deduction validation is the process of verifying a trade deduction against the underlying commercial agreement before deciding to clear it or dispute it: was the promotion valid, were its conditions met, is the claimed rate the contracted rate, and was the amount already settled another way. It is the step that separates deduction processing (coding and clearing what arrives) from deduction control (paying only what was actually owed).

Trade vs compliance: two families, two kinds of evidence

• Trade deductions — promotional allowances, rebates, pricing, billbacks — are claims about contracts. The evidence is the agreement, the transactions, and the settlement history: records the supplier holds.
• Compliance deductions — shortage, freight, OTIF, carton discrepancies — are claims about logistics. The evidence is proof-of-delivery, ASN, and carrier data. Different problem, different tooling.

Conflating the two is how suppliers end up with tools that almost work: a system holding contract data cannot adjudicate a shortage claim, and a compliance platform cannot tell whether a promotion’s rate was right.

The validation questions, made concrete

For each trade deduction: (1) match it to the program it claims; (2) confirm the program was in force for that product, account, and period; (3) recompute the amount from the contracted rate and the actual volume; (4) check settlement history for the double-dip. Done from spreadsheets, that is a two-to-three-week reconstruction per case — longer than most dispute windows. Done against a calculation ledger that wrote its evidence at accrual time, it is a query. The difference is the subject of deduction validation.
