Suppliers don’t lose the argument. They lose the clock.
Every retail deduction carries a dispute window, and the windows are shorter than the work. Verifying one trade deduction manually takes two to three weeks of spreadsheet archaeology — while AP chargeback windows close in 15–30 days. Aurgus inverts the race: the evidence is written when the accrual is written, so when the deduction arrives, the answer already exists. Aurgus is in design-partner stage, which we state plainly.
Once the window closes, the money is gone.
Dispute windows are set by each retailer’s supplier agreement, and they vary sharply by deduction type. The commonly published shape:
The shortest fuse — and the type most likely to contain contractual claims a supplier could actually win.
Longer window, different evidence: these turn on delivery and carrier data, not contracts.
The longest window — which is why they pile up unworked until the write-off threshold quietly clears them.
of revenue lost by Walmart suppliers to deductions and compliance fines.
of gross sales taken as retailer deductions across the industry — with a meaningful share of them invalid.
The case takes longer to build than the window stays open.
- Validating one trade deduction is a research project. Was the promotion valid on those dates? Did they hit the volume? Is the claimed rate the contracted rate? Was this amount already settled by credit memo? Each question means a different spreadsheet, a different owner, a different week.
- Two to three weeks per case — against a 15–30 day window. The math doesn’t work. Teams triage by size, work the biggest, and let the rest expire — which trains the deduction to keep coming.
- Weak documentation kills the disputes you do file. Ask any deduction team: the top reason an otherwise-valid dispute gets denied is that the supporting evidence was thin, late, or assembled from screenshots. The claim was right; the paper lost.
- Double-dipping hides in the gap. A promotional allowance settled by credit memo and deducted from a remittance is the classic leak — visible only to a system that sees both sides.
The evidence is written before the deduction arrives.
Aurgus doesn’t speed up the reconstruction. It removes it.
- 1
Every accrual carries its evidence from the moment it posts.
Which agreement, which rule, which source transactions, at what rate — written into the event log as of the date the amount was earned, not reconstructed at dispute time.
- 2
A deduction arrives; the answer already exists.
Match the deduction to the program it claims. Valid — under which agreement, already settled or not — or invalid, with the specific reason. Validation is a query, not a reconstruction.
- 3
The dispute package is the lineage, exported.
The agreement clause, the transactions, the arithmetic, the settlement history — machine-readable, dated, and ready inside the window instead of after it.
- 4
Both settlement paths visible at once.
Because credits and deductions reconcile against the same ledger, the allowance paid twice — once by credit memo, once by deduction — surfaces instead of hiding between AR and the program spreadsheet.
What Aurgus validates — and what it deliberately doesn’t.
Deductions split into two families, and they need different evidence. We serve one of them and say so.
Trade deductions — claims about what was contractually owed.
Promotional allowances, rebates, pricing, and billbacks. The evidence is the agreement, the transactions, and the settlement history — exactly what the calculation ledger already holds.
Compliance deductions — shortage, freight, OTIF, carton discrepancies.
Those disputes turn on proof-of-delivery, ASN, and carrier data that Aurgus does not hold. Pretending otherwise would add one more tool that almost works. Compliance-deduction specialists serve that half; Aurgus serves the contractual half, completely.
Deduction validation, honestly answered.
- What is a deduction dispute window?The deadline a retailer sets for disputing a deduction. Commonly published shape: AP chargebacks 15–30 days, shortage claims ~12 months, general AP deductions up to 24 months — exact windows set by each retailer’s supplier agreement. Once it closes, the deduction stands regardless of validity. See deduction dispute window.
- Why do suppliers lose valid disputes?The clock and the paper. Manual validation takes two to three weeks per case against windows measured in days — and when cases are filed, weak documentation is the top reason valid disputes get denied. The argument was right; the evidence lost.
- How does Aurgus validate trade deductions?By writing the evidence when the accrual is written. When a promotional-allowance deduction arrives, the answer already exists in the event log — which agreement, which transactions, settled or not. Validation is a query, not a reconstruction, and the dispute package is the lineage exported. Aurgus is in design-partner stage, which we state plainly.
- Which deductions does Aurgus NOT validate?Shortage, freight, OTIF, and carton discrepancies — those need POD/ASN/carrier data Aurgus doesn’t hold. We validate the contractual family: promotional allowances, rebates, pricing, billbacks. Stating the boundary is the point — a tool that claims both halves serves neither.
