Hello,
In the next few weeks, Late Shipment Rate will become a new Seller Performance Standard.What this means
Late Shipment Rate measures the percentage of self-fulfilled orders not handed off to the carrier by the Expected Ship Date. To meet Walmart Marketplace Performance Standards, you’ll need to maintain a Late Shipment Rate of 5% or less. This helps keep your account in good standing and supports a positive customer experience.
What to do next
Late Shipment Rate is available to view in your Performance dashboard, so you can monitor your status and take action early. To help meet and maintain a strong Late Shipment rate, you can:
Review your Late Shipment Rate regularly.
Ship orders on or before the Expected Ship Date.
Mark orders as shipped promptly after handing them to the carrier.
Ensure the first carrier scan falls on or before the Expected Ship Date.
Thank you for your business,
The Walmart Marketplace team
We notice that sometimes Walmart does not calculate the ship date correctly.
(Example today)
Order Date: 07/15/2026
Ship Date: 07/15/2026
Problem is we have the Lag Time for the item purchased set to 2 (and, Yes, we got approval)
So we have a case now to see what they say.
In addition, We had a customer contact us on 7/13 asking why her order was delayed. We replied back saying the Ship Date on the order is 7/13. She replied back saying she received a message from Walmart saying it’s delayed.
I assured her the order is not delayed and shipped on 7/13 as shown on the Walmart website. I told her it was a Walmart glitch, but person that replied to my case said “Rather, the carrier’s tracking provided an estimated delivery date of July 13, which the system used when determining whether a delay notification should be sent.”
However, no tracking was entered at the time we received the message from the customer. So we have another case about that.
Somehow the Walmart system sends out messages based on the ORDER DATE and NOT based off the ORDER DATE + LAG TIME (is what I am assuming)
