How do I manage my inventory?
The Inventory page focuses on strategies you can implement to maximize GMV and keep inventory in stock. It highlights the predicted daily GMV you may be losing due to out-of-stocks and the daily GMV at risk if a resupply doesn’t arrive within the next two weeks. We recommend you replenish your WFS inventory based on the suggested units to send, which considers your current available-to-sell inventory, your inbound inventory, and your forecasted sales for the next 8 weeks.
Additionally, the data table provides historical data from the past 30 days like daily sales and daily units sold to help you quickly understand how each item is performing. It also outlines the predicted out-of-stock date and suggested units to send to help you make inventory decisions. To replenish, just select individual items directly from this page and select the Send inventory button.
Understanding the calculations
All numbers in the Inventory page are based on actual sales over the previous 30 days. Daily averages are only calculated for the days the item was in stock during those 30 days. For example, if an item sold 30 units in the past 30 days and was only in stock for one day, the daily average sales for that item is considered 30 units. If an item sold 30 units in the past 30 days but was in stock all 30 days, the daily average sales for that item is considered 1 unit.
Table Metrics
Metric | Definition |
---|---|
Status |
|
Daily sales | Average GMV per day for the last 30 days. It’s total sales divided by number of days when you had at least 1 unit available to sell or sold that day. |
Daily units sold | Average number of units sold per day in the last 30 days. It's total units sold divided by number of days when you had at least 1 unit available to sell or sold that day. |
Available to sell | Units that are available for customers to place orders against. |
Reservations | Customer orders placed for an item but not yet fulfilled. We subtract reservations when calculating available stock, so the item isn't oversold. Once these orders ship, the reservations count will decrease. If there's a canceled order, we'll remove the reservation and make the item available again. |
Inbound units | Number of units that you’ve sent to WFS but haven’t been received yet. |
Days of supply | How many days we anticipate your current available and inbound inventory will last based on your daily forecasted sales demand. |
Out-of-stock date | The date we estimate you’ll run out of inventory, based on the days of supply. |
Suggested units | This is the quantity of units our algorithm suggests you send to WFS based on predicted sales demand for the next 8 weeks. To generate these suggestions, our algorithm considers several factors including past sales, seasonality, listing quality, pricing and more. |
To see more information about how we've calculated your units to send to WFS, select the suggested unit quantity to open the suggestion details. You'll see a breakdown of your available-to-sell units, how many units of this item that are currently inbound to WFS, your forecasted item sales for the next 1-4 and 5-8 weeks by date, and the units to send we calculated based on these numbers.

Inventory health report
Download this report for a snapshot of your item’s performance and in-stock rate. Track how many units are available to sell, how long they’ve been on the shelf, days of supply and sales. We also updated our insights and recommendations model to display more precise data on the recommended replenishment quantity. These suggestions are based on your forecasted demand for the next 8 weeks, minus what you currently have available to sell and what you already have on the way to WFS. You can use this information to make decisions on how much of each item you should send to WFS to be prepared for anticipated demand. The forecasts that fuel these suggestions are updated every Monday.

How do I maximize WFS sales?
Item conversion report
Not sure which items to bring to WFS? The Item Conversion Report identifies which seller-fulfilled items would perform best if you converted them to Walmart-fulfilled. It’s available to any seller who already has one Walmart-fulfilled item in their catalog.
We rank recommendations from highest expected sales to lowest, and the report is refreshed twice a month with the latest recommendations. We suggest acting quickly on high-priority recommendations to help make the most of your GMV penetration. The report also shows a recommended quantity to inbound based on each item’s expected sales and GMV potential for the 30 days after a newly-converted WFS item becomes available to sell.
To download your Item Conversion Report, log into Seller Center and go to Reports.

GMV penetration report
This report shows you what percentage of your total sales come from Walmart-fulfilled items. It gives you greater visibility into WFS sales at a weekly, daily, and item level. If your GMV penetration is low, you may be missing out on sales. Help maximize your sales by converting more items to Walmart-fulfilled or keeping your Walmart-fulfilled inventory in stock.

Restock these WFS items

This feature identifies the current opportunity cost of your out-of-stock and at-risk inventory that has forecasted sales demand. It encourages you to make inventory restock decisions based how much inventory we predict you may sell through. The suggested units to send are based on your 8-week forecast, taking into account what you currently have available to sell and the inventory already on its way to WFS. Once you decide to send inventory, you’ll see a selection of your items out of stock or at risk of going out of stock soon. Each item on this page features suggested quantities of each item to send to WFS, based on your predicted demand. The forecasts that generate these suggestions are updated every week.
Once you select which items to send to WFS, you’ll then complete the same inbound order creation experience you see today.
