Calculate your inventory

Learn how Walmart calculates your inventory by referring to the article How to update seller-fulfilled inventory: Overview. The Inventory API has several types of inventory quantities:

Quantity Type	Description
onHandQty	The total number of units in the warehouse. Understanding the overall inventory capacity ensures you have sufficient stock to meet demand.
availToSellQty	The number of units available to sell right now (on-hand minus any reserved). When a sale occurs, it can take several days for items to be released from the fulfillment center, so the reported inventory can include units that are not immediately available. This parameter shows the actual number of units in stock and ready for new orders.
reservedQty	The number of units set aside for orders already placed. Monitoring this value helps prevent overselling by clearly identifying which items are not available for new orders.
