Walmart deduction codes — triggers, evidence, windows.

What triggers it

Walmart's DC scanned receipts and could not match line items on the invoice to merchandise on the trailer. Often caused by short-pick at origin, pallet mis-label, or split shipments invoiced as one.

Evidence to dispute

Signed Bill of Lading (BOL), proof of delivery (POD) with retailer DC stamp, packing list, and outbound weight ticket from your 3PL. If the shipment was split, both BOLs.

Filing window

30 days from deduction post date in APDP

Typical success rate

70–85% when full POD packet is filed within window

Root-cause fix

Reconcile pick-list to packing-list to BOL at origin; require driver-signed BOL with carton count before trailer leaves.

What triggers it

DC scanned fewer cartons than the ASN/invoice declared. Most common on mixed pallets and floor-loaded trailers.

Evidence to dispute

Packing list, BOL, weighed shipment record, and trailer seal log. Photos of palletized load before sealing help if available.

Filing window

30 days from deduction post date in APDP

Typical success rate

60–75% when shipment was palletized and weighed at origin

Root-cause fix

Move from floor-load to palletized; weigh and photograph every outbound trailer; reconcile ASN against packing list before transmission.

What triggers it

DC has no record of receiving the PO that the invoice references. Often a routing or appointment mismatch — the merchandise arrived but was received under a different PO or appointment number.

Evidence to dispute

POD with retailer DC stamp, BOL referencing the disputed PO, MABD appointment confirmation, and the original PO acknowledgement.

Filing window

30 days from deduction post date in APDP

Typical success rate

75–90% when DC-stamped POD is available

Root-cause fix

Confirm PO number on every BOL and packing list; require carrier to capture stamped POD on delivery; reconcile PO acknowledgements weekly.

What triggers it

DC found shortage after carton was opened (inner-pack count low). Common on shrink-wrapped club packs and inner-case product.

Evidence to dispute

Bill of materials by case, manufacturing pack-out sheet, and outbound case-weight record. Photos of finished pallet before shrink-wrap when available.

Filing window

30 days from deduction post date in APDP

Typical success rate

40–60% — inherently harder than carton shortages

Root-cause fix

Audit pack-out line at random intervals; weight-verify finished cases against bill of materials before shipping.

What triggers it

Invoice price did not match the price on the PO or the negotiated deal sheet. Most common after promo periods end and pricing reverts.

Evidence to dispute

Original PO with pricing, signed deal sheet or contract amendment, and the matching invoice. For promo periods, the promo authorization with effective dates.

Filing window

60 days from deduction post date in APDP

Typical success rate

80–95% when deal sheet documentation is complete

Root-cause fix

Single source of truth for retailer pricing per SKU per period; reconcile invoice prices to deal sheet weekly before billing.

What triggers it

Third-party audit firm (Connolly, PRGX, etc.) retroactively flagged a duplicate payment, missed allowance, or pricing error from prior years. Often appears 12–36 months after the original transaction.

Evidence to dispute

Original PO, original invoice, original remittance showing the deduction was already taken (or that the allowance was already paid). Bank reconciliation when payment is in question.

Filing window

Typically 90 days to respond from claim date (varies by audit firm)

Typical success rate

50–70% — many post-audit claims are valid; the rest are double-counted deductions

Root-cause fix

Maintain a post-audit response file by year; never pay a post-audit claim without checking it against the original remittance.

What triggers it

Walmart's OTIF program fines suppliers ~3% of cost-of-goods on POs that arrive late or short to the DC, measured against the Must Arrive By Date (MABD).

Evidence to dispute

Carrier exception report, dock appointment confirmation with date/time, GPS/ELD record from carrier, and DC receiving timestamp. For 'in-full' failures, the original PO acknowledgement.

Filing window

30 days from fine date in the OTIF portal

Typical success rate

40–55% — many OTIF events are valid; the disputable ones are receiving errors and carrier exceptions

Root-cause fix

Audit the 4–6 lanes generating most fines, not all lanes; align MABD-to-ship-date math by mode; book dock appointments earlier in the window.
