Top 5 Walmart Retail Chargebacks (And How to Avoid Them)

The top five Walmart chargebacks are OTIF violations, ASN and EDI errors, barcode and labeling defects, PO accuracy failures, and pallet and load non-compliance. Each is tied to Walmart's OTIF or SQEP programs and carries specific financial penalties, ranging from 3% of COGS for OTIF failures to $200 per defect plus $1 per unit for SQEP violations. The average Walmart supplier loses 5.8% of invoice value to deductions. Understanding what triggers each chargeback and how to prevent it is the fastest way to protect your margins.

Why Walmart Chargebacks Add Up Faster Than Suppliers Expect

Walmart issues chargebacks to suppliers for one stated reason: to improve supply chain performance and keep costs low for customers. The company is not trying to profit from penalties. But that does not make the financial impact any less real for suppliers.

Industry data shows the average Walmart supplier loses 5.8% of invoice value to deductions, and some lose over 30%. A brand shipping $2 million annually at that average rate is writing off $116,000 a year in preventable losses. Less than 20% of those deductions ever get disputed.

This guide breaks down the five most common Walmart chargebacks, what triggers each one, what it costs, and what suppliers can do right now to prevent them. All five are rooted in Walmart's two core compliance programs: OTIF (On-Time In-Full) and SQEP (Supplier Quality Excellence Program).

#1: OTIF Violations (On-Time In-Full)

OTIF chargebacks are the largest single source of compliance fines for most Walmart suppliers. Walmart's OTIF program measures whether shipments arrive at distribution centers on time and with the correct quantity of product ordered. Both dimensions are tracked at the case level, not just the purchase order level.

What Triggers It

•       Shipment arrives after the Must Arrive By Date (MABD) window.
•       Shipment arrives before the MABD window. Early arrivals are non-compliant because Walmart DCs plan capacity tightly and cannot absorb early freight.
•       Fewer cases delivered than ordered. The in-full threshold is 95% of ordered cases.
•       On-time threshold for prepaid suppliers is 90% of cases. Collect suppliers must be 98% ready for pickup.

What It Costs

OTIF chargebacks are calculated at 3% of the cost of goods sold (COGS) on all non-compliant cases. Walmart shifted from monthly billing to quarterly charging in 2024, giving suppliers slightly more time to identify and dispute issues, but the 3% penalty rate is unchanged.

Real-world example: A brand shipping $50,000 per week that misses its OTIF target by 10% faces $1,500 in weekly fines, or roughly $78,000 per year.

How to Prevent It

•       Treat OTIF as a weekly operational metric. Check your OTIF scorecard in Retail Link every week, not at month end.
•       Understand your MABD window precisely. Know whether you have a one-day or two-day window, and build buffer time into your shipping schedule accordingly.
•       Vet your carriers. Use 3PLs or consolidators with documented Walmart experience and strong on-time delivery records.
•       Communicate early. If a shipment is going to miss its window, notify Walmart via the Transportation Portal before the MABD, not after.

 

Dispute tip: OTIF fines are invoiced through HighRadius. You have a dispute window of 15 to 30 days from posting. The recommended practice is to wait until the fine is invoiced, then dispute through HighRadius with HOST PO numbers, item numbers, and charge amounts.

#2: ASN and EDI Errors (SQEP Invoice Defects)

ASN (Advance Ship Notice) and EDI errors are consistently among the most common chargebacks across all major retailers, and Walmart is no exception. Under SQEP, these are classified as Right Invoice defects. They occur when the electronic documentation does not accurately represent the physical shipment.

What Triggers It

•       No ASN submitted: $25 per PO for ASNs not downloaded by Walmart's system.
•       ASN quantity mismatch: The quantity on the ASN does not match the quantity physically received. Fine is $0.25 per case over or under.
•       Missing SSCC labels: Cases are missing the 18-digit Serial Shipping Container Code barcode that ties the pallet to the ASN.
•       ASN submitted after physical arrival. Walmart requires the ASN before the shipment reaches the DC. Submitting it after arrival defeats the purpose of system-directed receiving.
•       For food and beverage suppliers, ASNs must now include FSMA 204 Key Data Elements (KDEs) per Walmart's August 2025 mandate. Non-compliant ASNs will be tracked in the SQEP Dashboard.

What It Costs

ASN defects are billed monthly. The fine structure is: $25 per PO for missing ASNs, and $0.25 per case for quantity mismatches. These appear small per incident but accumulate quickly across high-volume shipments.

How to Prevent It

•       Submit ASNs before the shipment physically arrives at the DC. Build this into your warehouse workflow as a required step before any truck departs.
•       Ensure your ASN data matches the PO exactly in terms of item, quantity, and pack configuration.
•       For food and beverage items, configure your EDI 856 to include FSMA 204 KDEs now, ahead of enforcement.
•       Audit your EDI provider regularly to ensure mappings are current. EDI errors from outdated configurations are a common hidden cause of ASN chargebacks.

 

SQEP dashboard tip: Retail Link > Apps > SQEP Dashboard shows ASN defects broken down by sub-type. Review it weekly and use the FixIt Inspections tool to communicate corrective actions directly to your Inbound Quality Manager.

#3: Barcode and Labeling Defects (SQEP Phase 2)

Barcode and labeling defects fall under SQEP's Phase 2 compliance requirements. Walmart uses radio frequency identification (RFID) scanners and automated systems at its distribution centers to read incoming freight. When barcodes fail to scan or labels are missing or inaccurate, Walmart must perform manual intervention, which generates a chargeback to recover those labor costs.

What Triggers It

•       Unscannable or defective barcodes: Poor print quality, incorrect white space (quiet zone), wrong barcode format, or barcodes in the wrong position on the case.
•       Label compliance failures: Labels missing required information such as item description, vendor stock number, item number, or carton count. Carton markings appear on only one side of the box rather than two.
•       Hazmat compliance: Required hazmat labels are missing or obstructed.
•       SSCC-18 label missing on pallets or cases for DSDC (Direct Store Delivery Consolidation) shipments.
•       For apparel and footwear, item-specific label requirements apply, including a Walmart item number.

What It Costs

The fine structure depends on how the defect is caught. For defects found by manual inspection: $200 administrative fee per defect per PO, plus $1 per package with defects. For defects flagged by automated scanners: $1 per case, with no administrative fee. Note that automated-scan fines have been on hold, but the manual inspection structure remains active.

Example: A shipment of 48 units with one barcode defect caught by manual inspection results in a chargeback of $248 ($200 admin fee plus $48 at $1 per unit).

How to Prevent It

•       Audit your barcode print quality before every shipment. Test barcodes with a scanner or smartphone app. Never assume a label is readable because it is printed.
•       Confirm barcode specifications against the current Walmart Secondary Packaging Supply Chain Standards. Find this guide at Retail Link > Supplier Academy.
•       Ensure carton markings appear on two sides of every case, not just one.
•       Service your label printers regularly. Faded, smeared, or streaked labels are a leading cause of scan failures at Walmart DCs.
•       Use Retail Link > Apps > SQEP Dashboard to monitor your barcode compliance score and identify problem items before they repeat.

#4: PO Accuracy Failures (SQEP Phase 1)

Purchase order accuracy is the foundation of SQEP compliance. Phase 1 of SQEP focuses entirely on whether what a supplier ships matches what Walmart ordered. Any discrepancy between the physical shipment and the purchase order is a PO accuracy defect and generates a chargeback.

What Triggers It

•       Overage: The number of cartons or cases shipped is greater than what the PO specified. Walmart reserves the right to refuse payment for over-shipped units.
•       Canceled PO: Supplier ships against a PO that Walmart had already canceled.
•       Canceled line item: Supplier ships a product on a PO line that was canceled.
•       Item not on PO: An extra item is included, or a substitution is made with a different UPC than what was ordered.
•       Wrong pack quantity: The vendor pack size shipped does not match the pack configuration on the PO.
•       Date issue: A food item is shipped after its Best-By or expiration date, or outside the date agreement with Walmart.

What It Costs

PO accuracy defects are billed at $200 per defect per PO plus $1 per case impacted. For high-volume shipments with multiple defect types, these fines stack quickly. A PO with two separate accuracy defects affecting 100 cases would generate a fine of $500.

How to Prevent It

•       Verify item setup in Walmart's system before shipping. Confirm UPCs, pack sizes, and item numbers in Item 360 match your physical product and PO exactly.
•       Build a PO review step into your pick-and-pack process. Warehouse staff should cross-check PO line items, quantities, and pack configurations before sealing any case.
•       Check for PO cancellation notifications in Retail Link before every shipment. Shipping against a canceled PO is one of the most avoidable SQEP defects.
•       Never substitute items without Walmart approval. Even a minor UPC variation counts as an unauthorized item.

 

System check: Use the FixIt Inspections tool in Retail Link to view defect examples from Walmart's DC receiving teams. This shows exactly what auditors flagged on recent shipments and helps you identify recurring PO accuracy issues before they repeat.

#5: Pallet and Load Non-Compliance (SQEP Phase 3)

Pallet and load compliance falls under SQEP Phase 3. These chargebacks are issued when the physical integrity or configuration of a shipment does not meet Walmart's standards. Poor pallet builds slow down DC processing and, in some cases, create safety risks for receiving staff and equipment.

What Triggers It

•       Pallet height exceeds 96 inches. Oversized pallets cannot fit Walmart's DC racking systems.
•       Pallet overhang: Cases extend beyond the edges of the pallet. Overhang is not acceptable under any circumstances.
•       Pallet quality: Pallets that are broken, damaged, or below Grade A standards.
•       Poor pallet securement: Missing trays for bagged items, inadequate stretch wrap, or unstable pallet builds that shift during transit.
•       Load segregation failures: Incorrect grouping of items, improper separation of different PO types, or non-palletized freight.
•       Pallet labeling defects: Pallet labels missing, incorrect, or not visible without stripping the shrink wrap.

What It Costs

Pallet compliance defects are billed at $200 administrative fee per PO plus $4 per pallet. Load compliance defects carry $200 administrative fee per PO plus $20 per load. For a single truckload with five non-compliant pallets and one load issue, the total fine would be $240.

How to Prevent It

•       Measure pallet height before loading. 96 inches is a hard ceiling, and exceeding it will generate a chargeback regardless of what caused the overage.
•       Use Grade A pallets only. Inspect every pallet before use and replace any with cracked boards, loose fasteners, or structural damage.
•       Properly block and brace all loads for transit. Pallet builds that arrive shifted or unstable generate load compliance defects even when the individual pallets were built correctly.
•       Label every pallet with the correct SSCC-18 label, visible without removing stretch wrap.
•       For FTL and LTL shipments, confirm your 3PL or warehouse team is applying Walmart's current pallet build specifications. Outdated SOPs at the warehouse level are a common root cause of pallet defects.

Frequently Asked Questions

What is the most common Walmart chargeback?

OTIF violations are the most costly and most frequently discussed Walmart chargebacks. They are assessed at 3% of COGS on non-compliant cases and billed quarterly. ASN and EDI errors are the most operationally frequent, particularly for suppliers managing high SKU counts or multiple shipping locations.

How do I dispute a Walmart chargeback?

Log in to Retail Link and go to the Accounts Payable Disputes Portal for chargebacks, or the Supplier Dispute Portal for deductions. Dispute windows are 15 to 30 days from the chargeback posting date, depending on type. OTIF chargebacks are disputed through HighRadius. Have your HOST PO numbers, item numbers, and charge amounts ready before submitting.

Can I dispute a Walmart chargeback after fixing the issue?

No. Correcting the operational issue does not automatically reverse a chargeback. Every chargeback must be formally disputed through the appropriate portal to receive reimbursement. Fixing the root cause prevents future chargebacks but does not recover money already deducted.

How do I monitor my Walmart compliance performance?

Use two dashboards in Retail Link: the OTIF Scorecard for delivery performance, and the SQEP Dashboard for packaging, labeling, barcode, and PO accuracy defects. Both should be reviewed weekly. The FixIt Inspections tool within SQEP lets you see specific defect examples from DC receiving teams and communicate corrective actions directly.

What happens if I keep receiving the same Walmart chargeback?

Repeated non-compliance at Walmart is treated as an operational risk, not just a billing issue. Persistent OTIF or SQEP failures can result in reduced purchase orders, loss of shelf space, removal from the product modular, or termination of the supplier relationship. Walmart has stated clearly that chargebacks are a tool to drive improvement, not a revenue stream.

Conclusion

The top five Walmart chargebacks share a common trait: all of them are preventable. OTIF violations, ASN errors, barcode defects, PO inaccuracies, and pallet non-compliance all trace back to operational gaps that can be identified and closed before freight leaves your facility. Suppliers who check their Retail Link dashboards weekly, audit their EDI configurations regularly, and hold their 3PL partners to Walmart's standards consistently outperform those who manage compliance reactively.
