How to Reserve (or pause) Inventory
Reserved Inventory refers to the count of inventory that is 'reserved' and not able to be sold on the sales channel. It is often used in preparation for a flash sale, or to withhold inventory for potential returns / exchanges.
How to Reserve Inventory
- Go to the product dashboard (https://app.shiphero.com/dashboard/products)
- Choose the product you would like to reserve inventory for
- On the detail box, click edit:

Update the "Reserve" field and then click "Update
Determining Available Units
- Reserved inventory is NOT taken into consideration when calculating the 'Available' units within ShipHero. Available units are calculated as follows:
AVAILABLE = (# On Hand) - (# Allocated) - (# Backorder) + (# Sell Ahead)
In the example above, we indicate 96 units available because 4 units are allocated for orders (not available for use).
- Reserved inventory IS taken into consideration when calculating 'Available' units for your Sales Channel. Available units are calculated for your sales channel as follows:
SALES CHANNEL QUANTITY = (# On Hand) - (# Allocated) - (# Backorder) + (# Sell Ahead) - (# Reserved)
In the example above, we indicate 90 units available because 4 units are allocated for orders and 4 units are reserved (not available for use).
Inventory Terms
On Hand: The total # of units physically in the warehouse. On Hand is NOT what is published to your sales channel as available for sale.
Allocated: The # of units that have already been put aside for open orders pending fulfillment.
Reserve: The # of units that you do not want to sell in your Sales Channel (units to be reserved for returns or a flash sale).
Available: The # of units pushed to your Sales Channel and available for purchase by customers. Calculated as # On Hand - # Allocated - # Backorder + # Sell Ahead - # Reserve.
Backorder: The # of units owed to customers for open orders that do not have stock in the warehouse.
Sell Ahead: # of units coming in on a Purchase Order that should be included as 'available' on your Sales Channel, even though you have not yet received the inventory in the warehouse.
Be CAREFUL...
Reserved inventory is not taken into consideration when placing manual orders. Reserved inventory is only taken into consideration when pushing the # of available items to your Sales Channel.
Using a negative number in Reserved Inventory will increase the # of units available in the sales channel.
