Changing lag time for Walmart products

IMPORTANT – Please keep in mind that fulfillment lag time set above 1 day have to be approved by Walmart. 1 day of lag means a seller has about 48 business hours to ship the order. If you will set it above one day without a permission your quantity feeds will be rejected by Walmart API. You can request extended fulfillment lag time on your Walmart Seller Center by submitting a support case.

In the body of the Partner Support case, you must provide a list of product categories where all or some SKUs require exceptions. Also you need to address the following questions in the body of the case:

  1. How many SKUs in each category will require an extended lag time?
  2. How many days of Lag Time are you planning to add to the SKUs in these categories?
  3. Why are you requesting an exception and why you cannot support the same or next day shipping in these categories?
  4. Do you have inventory in stock in your warehouse for the SKUs that require exceptions? Or do you source from a third-party vendor?
  5. What percentage of your catalog do these SKUs represent?
  6. What percentage of your total sales on Walmart Marketplace do these SKUs account for?
  7. If an exception is rejected, how will it impact your business on Walmart Marketplace?
