Crazy Vendor finds Walmart Fulfillment Services (WFS) inventory that went missing, arrived short or was never credited, tracks every investigation to payout, and lets you keep 100% of what Walmart reimburses. Amazon FBA is covered in the same dashboard.
Why WFS reimbursements slip through
Walmart only reimburses inventory it confirms was lost or misplaced while in WFS possession, and only when you open an investigation in time. According to Walmart’s WFS guide, a receiving investigation has to be opened between 10 and 50 days after the shipment is delivered to the fulfillment center. Miss that window and the money is gone, and Walmart states that no appeals are accepted.
Most sellers do not have time to compare every shipping plan against what was received, so short shipments and missing units go unnoticed.
How Crazy Vendor recovers WFS funds
- Continuous discrepancy scanning: compares your shipping plans, receiving data and returns to flag units that look lost, short-received or uncredited.
- Case tracking from detection to payout: every case has a status, documentation and history in one place.
- Claim-ready summaries: case insights you can submit through Walmart Seller Center, the official channel.
- Automatic payout matching: detects when reimbursement funds arrive and matches them to the open case.
- Historical reconciliation: reviews past data for funds that were missed.
- Amazon FBA in the same view: one dashboard for Amazon and Walmart reimbursements.
What you need for a WFS investigation
Walmart’s documentation requirements depend on how you shipped:
- Walmart Preferred Carrier (WPC) parcel: no extra documents.
- Non-WPC parcel: proof of delivery showing the street address.
- LTL / FTL: bill of lading with shipper and carrier pickup signatures.
Crazy Vendor keeps the shipment details and documents attached to each case, so they are ready before the 50-day window closes.
No commission on recovered funds
Recovery agencies typically take a percentage of every reimbursement. Crazy Vendor charges no commission on resolved cases, so recovered funds stay with you. See pricing or the full Amazon and Walmart reimbursements recovery page.
