What Is OS&D?
OS&D stands for Overage, Shortage, and Damage—three common shipment issues that can lead to retailer chargebacks. While each issue is handled differently, many deductions can be disputed when supporting documentation proves the shipment was accurate.
Maintaining accurate shipping records is the best defense against invalid OS&D deductions.
Overages
An overage occurs when a shipment contains more product than the retailer ordered. Although less common than shortages, overages may result in compliance charges or returned merchandise.
| Retailer | Typical Handling |
|---|---|
| Walmart | May be charged as an SQEP compliance defect. |
| Kroger | Recorded as Code 7 (Overage). |
| Target | May result in Over-Ship or Return-to-Vendor charges. |
Shortages
Shortages occur when the retailer receives fewer products than expected. Walmart commonly uses deduction codes for concealed shortages, merchandise billed but not shipped, carton shortages, and shipments reported as not received.
Damages
Damage deductions are issued when products are received in poor condition due to handling, transportation, weather, or other factors. Common examples include concealed damage, freight damage, and returned damaged merchandise.
Documents Needed for Disputes
- Purchase Order (PO)
- Supplier Invoice
- Signed Proof of Delivery (POD)
- Bill of Lading (BOL)
- Payment remittance or adjustment documents (if available)
- Warehouse shipping confirmations
- Relevant email communication
- Supporting contracts or agreements
Where to Submit Disputes
| Retailer | Dispute Method |
|---|---|
| Walmart | Accounts Payable Dispute Portal (APDP) |
| Kroger | Partner Pass |
| Target | Synergy |
Best Practices
- Verify shipment quantities before products leave the warehouse.
- Maintain complete shipping documentation for every order.
- Regularly audit warehouses and logistics providers.
- Implement standard operating procedures (SOPs) to reduce shipping errors.
- Review recurring deductions to identify operational improvements.
Conclusion
OS&D deductions can significantly impact supplier profitability, but many invalid deductions can be successfully challenged with accurate documentation. By maintaining organized records, monitoring shipment quality, and improving logistics processes, suppliers can reduce unnecessary chargebacks and strengthen retail compliance.
