Notes

You must have an existing fulfillment center added to your Seller Center account before you can update your inventory. After you’ve added the fulfillment center, wait at least four hours before attempting to complete an Inventory template. If you attempt to update inventory before your facility is fully processed in our system, you will receive an error.

Frequently asked questions

How can I find my fulfillment center ID?

How can I check the status of my inventory update?

How can I update my fulfillment center information?

My item is appearing as out of stock on Walmart. Why does it show that I have inventory Reserved and On hand in Seller Center?

Once an item has been purchased by a customer, it is added to your reserved inventory quantity until you’ve marked it as shipped. If your on hand and reserved inventory quantities are the same amount, this means customers have purchased all inventory On hand and the item will appear as out of stock on Walmart.com.

To avoid this, we strongly encourage you to provide Walmart with an on hand inventory quantity that is at least 20 more than the reserved inventory quantity. For example, if you have 30 shirts in your reserved inventory you should provide an on Hand inventory quantity of 50.

How do I zero out my Reserved inventory quantity?
