Walmart Marketplace seller performance standards, and how eBay's compare
Updated · Rotomal
Walmart asks Marketplace sellers to keep cancellations at 2% or below, on-time delivery at 90% or above, valid tracking at 99% or above, late shipment at 5% or below, seller response within 48 hours on 95% of inquiries, and negative feedback, item not received and return rates within set limits, measured over the last 30 or 60 days. Missing a standard can lead to suppression, suspension or termination. eBay's equivalent rules are evaluated monthly on the 20th and focus on transaction defects, cases closed without seller resolution and late shipments.

From Walmart's Seller Performance Standards guide, last updated 28 July 2026. Walmart notes that if you use WFS, most performance metrics are met for you, except negative feedback.
What drives Walmart's shipping metrics
- On-time delivery: late hand-over to carrier, late shipment, no carrier scan, carrier delays, ship location or carrier method mismatch, and carrier delivery estimates later than promised count against you; carrier exceptions and weather do not.
- Valid tracking: no carrier scan, invalid tracking ID or URL, misleading tracking and non-integrated carriers. Walmart asks you to share tracking only after the package is tendered to the carrier.
- Cancellation: out-of-stock, pricing errors, an expired ship window and wrongly marking an address as not serviceable count; customer-requested cancellations do not.
How eBay compares
| eBay metric | Top Rated | Below Standard |
|---|---|---|
| Transaction defect rate | 0.5% or less, from no more than 3 buyers | Over 2%, from more than 4 buyers |
| Cases closed without seller resolution | No more than 2, or 0.3% | Above 2 or 0.3%, whichever is higher |
| Late shipment rate | No more than 5, or 3% | No minimum on its own |
| Tracking uploaded and validated | At least 95% of transactions | Not specified |
eBay evaluates on the 20th of each month, using the last 3 months if you had more than 400 transactions, otherwise the last 12 months (checked 7 November 2026).

Questions
Can I see these metrics through an API?
Walmart says you can monitor them in the Performance dashboard, the Walmart Seller app or through its Seller Performance APIs. eBay offers a seller standards profile in its Analytics API, and Amazon a seller performance report in the Selling Partner API.
What does Below Standard cost on eBay?
eBay says items may rank lower, selling limits may fall, Promoted Listings are blocked, funds may be held until tracking shows movement, and final value fees may rise from the 1st of the next month.
