Walmart Fulfillment Services (WFS)
Participation in the Walmart Seller app is by invitation-only and not available to all Marketplace sellers. If you’re interested in downloading the app, fill out this form.
You can update inventory for an existing fulfillment center or add a new one with the Walmart Seller app. Follow these instructions to update your inventory.  
Tap Catalog and select the item you want to update to view Item details.   
Scroll to the Inventory section and tap Edit.  
Update the On hand field in the existing fulfillment center or select Add fulfillment center and enter the new value.
 Tap Save  to reflect the updated inventory values.  
Check out the Inventory Management checklist to make sure you’re acknowledging your orders and keeping your items in stock. You can also bulk acknowledge your orders by bulk filtering your new orders.
It may take an hour to reflect price and inventory updates. Additionally, you can only edit Seller-fulfilled inventory from the app. You can’t update inventory for multi-box related items. All WFS-related inventory modifications need to be done from desktop.
