Walmart announced an update to how Expected Ship Dates are calculated for seller-fulfilled orders.
The main change is simple:
If your fulfillment lag time is greater than 0 days, Walmart will no longer use the order cutoff time when calculating the Ship By date.
Instead, Walmart will calculate the Expected Ship Date based only on the order date.
This change is designed to create more consistent delivery promises for customers, but for sellers it may result in earlier Ship By dates than before.
How it worked before
Previously, cutoff time affected Ship By dates even when sellers used fulfillment lag time.
For example:
- If your lag time was 1 day
- And your cutoff time was 2 PM
- Orders placed after 2 PM could sometimes receive an additional business day before shipment was required
Now that behavior changes.
How it works now
If your fulfillment lag time is:
- 0 days → cutoff time still matters
- Greater than 0 days → cutoff time is ignored
Walmart now simply adds the lag time to the order date.
The table below from Walmart explains the new logic clearly.
| Fulfillment Lag Time | Order Received | Ship By Date |
|---|---|---|
| 0 days | Before cutoff | Same business day |
| 0 days | After cutoff | Next business day |
| 1 day | Anytime (order cutoff does not apply) | Order date + 1 business day |
| 2 days | Anytime (order cutoff does not apply) | Order date + 2 business days |
What this means for sellers
This update may create earlier shipping deadlines for some sellers.
Especially if you previously relied on cutoff times to gain extra processing time for orders placed later in the day.
Example:
Before:
• Seller had a 1-day fulfillment lag
• Cutoff time was 2 PM
• Order placed Friday at 5 PM
• If the seller did not operate on weekends, Walmart could previously push the Ship By date to Monday
Now:
• Same 1-day fulfillment lag
• Same Friday 5 PM order
• Cutoff time is ignored when lag time > 0
• Walmart calculates directly from the order date and seller working days, which may create earlier Ship By expectations than before
Why this matters
Late shipments can impact:
- On-Time Shipping metrics
- Account health
- Delivery promises
- Customer experience
Because of this, Walmart recommends reviewing your fulfillment lag time settings to make sure they still match your actual warehouse operations and processing capacity.
Our recommendation
If you are a Walmart seller:
- Review your fulfillment lag settings
- Test late-day order scenarios
- Make sure your shipping team can meet the updated expectations
- Pay special attention before weekends and holidays
Even small changes in Ship By calculations can affect operational workflows.
