What You Need to Know to Fight Chargebacks with Walmart

If you're a supplier doing business with Walmart, you’ve likely encountered chargebacks—those pesky deductions that can quietly chip away at your profits. Whether due to shipment discrepancies, missing documentation, or timing issues, chargebacks are part of the cost of doing business with big-box retailers. But that doesn't mean you should accept them without a fight.

Here’s what you need to gather and the internal resources you’ll need to effectively fight chargebacks with Walmart:


1. Understand Walmart’s Compliance Standards

Before you can dispute a chargeback, you need to understand why it happened. Walmart issues chargebacks for violations of their compliance policies, which can range from incorrect EDI documents to late shipments.

Start by reviewing:

  • Walmart’s Supplier Agreement
  • Retail Link Documentation (especially the SQEP—Supplier Quality Excellence Program guidelines)
  • Chargeback Reason Codes listed in the deduction documentation

2. Gather Essential EDI Documents

Walmart bases many chargebacks on EDI-related issues. You’ll need to pull the following:

  • EDI 856 (Advance Ship Notice): Was it sent on time and with the correct format?
  • EDI 810 (Invoice): Does it match the PO exactly?
  • EDI 850 (Purchase Order) and EDI 997 (Acknowledgment): Useful for showing intent and timing.

Make sure timestamps and control numbers align.


3. Shipping and Delivery Records

Chargebacks due to delivery or labeling issues require:

  • Proof of Delivery (POD)
  • Carrier tracking details
  • BOL (Bill of Lading)
  • Shipping labels (Walmart is strict on GS1 and SSCC standards)

Photos of pallets, cartons, and labels can also support your case.


4. Internal Communication Logs

If there were system outages, holiday schedules, or supply chain issues that caused the error, internal documentation can help explain the issue. Collect:

  • Email chains
  • Help desk tickets
  • Warehouse reports

This supports mitigation or exception requests.


5. Use Retail Link to Dispute

All chargeback disputes must be submitted through Retail Link’s Accounts Payable Disputes Portal (APDP). You'll need:

  • Deduction ID
  • Reason for dispute
  • Supporting documentation (PDF format preferred)

Time is limited—disputes must usually be submitted within 90 days of the deduction.


6. Work with Your EDI/Integration Partner

Often, the issue is technical—wrong mapping, late transmission, or unacknowledged messages. Your integration partner (like Crackerjack-IT) should be looped in early to:

  • Audit transaction logs
  • Identify mapping or communication failures
  • Automate report generation for faster dispute submissions

Final Thoughts

Fighting chargebacks with Walmart isn’t about luck—it’s about preparation, documentation, and responsiveness. Set up clear internal workflows, keep a chargeback checklist on hand, and maintain a strong relationship with your EDI provider. With the right resources and tools, you can recover thousands in disputed deductions—and stop unnecessary losses before they start.
