For Walmart suppliers, deductions and claims are part of the invoice-to-cash process. Even when invoices are submitted correctly, adjustments can reduce the final payment received. These deductions are not random. Walmart has a structured process for handling invoices, identifying mismatches, and applying claims or chargebacks where rules are not met.
The good news is that suppliers who understand how Walmart manages deductions can anticipate where issues occur and put strategies in place to prevent or recover lost revenue.
The Invoicing Life Cycle at Walmart
Walmart uses a strict invoice-to-cash process to ensure suppliers are paid correctly. Invoices must align with purchase orders and receipts before payment is approved. Key steps include:
- Invoice Handling: Invoices are validated against purchase orders and receipts in Walmart’s system. Any differences in cost, quantity, or allowances can trigger a claim. For more information on how invoices flow through Walmart systems, visit our Accounts Payable Dispute Portal (APDP) Guide.
- Payment Terms: Cash discounts and negotiated payment terms are applied automatically. Suppliers need to understand whether terms are based on shipment date, receipt date, or negotiated contract terms.
- Shipping and Routing Guides: Walmart enforces compliance with routing rules. Shipments that do not follow guidelines can create deductions tied to logistics. Learn more about Walmart ASN setup and compliance in our ASN Best Practices Guide.
- Allowances and Agreements: Any agreed-upon allowances must appear correctly on the invoice. Missing allowances often result in deductions. For a deeper dive into this topic, read our Walmart Allowance Complete Supplier Guide.
What Walmart Means by Claims, Deductions, and Chargebacks
Walmart separates adjustments into three categories:
- Claims: Reductions in payment caused by mismatches between the purchase order, receipt, and invoice. Common examples include item cost differences, shortages, or allowances that were not listed on the invoice.
- Deductions: Reductions in payment that are based on pre-negotiated agreements, such as returns, co-op programs, defective allowances, or post-payment audits.
- Chargebacks: Reductions caused by failure to meet Walmart’s supply chain standards. This includes programs like On Time In Full (OTIF), Supplier Quality Excellence Program (SQEP), and other supplier compliance expectations.
For suppliers, the category matters because each requires different documentation and resolution steps.
Why Walmart Uses Deductions
The goal behind deductions is accuracy and compliance. Walmart wants to ensure it only pays for goods that were ordered, shipped, and received correctly. Deductions protect Walmart from overpayments, duplicate billing, or invoices that do not meet negotiated terms.
For suppliers, this means even small errors can create deductions. Price discrepancies, shipment delays, missing documents, or packaging issues can all reduce payments if they fall outside Walmart’s compliance standards.
Walmart uses a detailed system of deduction codes to effectively manage deductions from vendor payments. If you need to understand Walmart deduction codes, see our Walmart Deduction Codes Explained.
Identifying and Managing Deductions
Suppliers can track and manage deductions through Walmart’s Retail Link and Supplier Performance dashboards. These tools provide visibility into:
- Payment status for invoices
- Claims applied against specific POs
- Compliance deductions related to supply chain or shipping errors
To learn how to navigate Retail Link effectively, visit our Walmart Retail Link Guide.
Best practice is to review deductions frequently, not just at month-end, so that disputes can be filed within Walmart’s timelines.
Requesting Backup for Claims and Deductions
When a deduction is applied, suppliers can request supporting backup documentation through Walmart’s portals. Backup typically includes:
- Receiving reports
- Compliance audit records
- Freight or shipping details
- Notes on allowances or defectives
Backup is critical for determining whether a deduction is valid or disputable.
How to Dispute Walmart Claims and Deductions
If a supplier believes a deduction was applied in error, it can be disputed through Walmart’s systems. Key steps include:
- Review the claim details in Retail Link or the Supplier Performance dashboard.
- Collect required documents such as the purchase order, invoice, and proof of delivery. For help with PO tracking, see our Guide to Walmart PO Numbers and the NOVA Tool.
- Confirm whether the issue stems from supplier error, a compliance miss, or a system mismatch.
- Submit the dispute with full documentation through Walmart’s portal.
Strong documentation is the most important factor in successful dispute resolution. 
Best Practices to Reduce Future Deductions
Walmart’s process is designed to enforce accuracy. Suppliers who want to reduce deductions should:
- Ensure invoice accuracy by matching all details to purchase orders, including costs, allowances, and pack sizes.
- Follow routing and shipping guides to avoid logistics-related deductions.
- Maintain organized records of invoices, bills of lading, and merchant agreements to respond quickly to claims.
- Monitor compliance metrics in Retail Link and fix recurring errors at the root cause.
By treating deductions as part of the invoicing cycle rather than an afterthought, suppliers can reduce losses and recover revenue more effectively.
