When orders sync into SKULabs, the stock needed to fulfill them is reserved. Reserved stock stays in your on-hand count but is no longer available to sell, which prevents overselling. Available stock is your on-hand count minus reserved stock.
When is stock reserved and released?
An open order reserves its items as soon as it is imported or created.
The reserve is released when the order is shipped, cancelled or archived. If you ship part of an order, only the shipped quantity is released.
If your deduction method is Per scan, the reserve is also released when the order is cleared.
Orders tagged Hold - Archived (see Disable automatic order archiving) stay open and keep reserving stock.
Order reservation methods
You choose how reserves are split across your warehouses at Settings > Inventory > Settings > Order reservation method. You can change it at any time; reserves are recalculated from your open orders on the next inventory sync.
Account-wide (default)
Reserves are shared across all warehouses. Every store sees the same available quantity for an item, no matter which warehouse ships the order.
Example: Warehouse A has 100 units and Warehouse B has 50. Store X has an open order for 10 and Store Y has one for 5. Available stock is 150 - 15 = 135 in every store.
Warehouse-linked
Each order reserves stock in the warehouse assigned to ship it. If an order has no warehouse assigned yet, its reserve is spread across the warehouses linked to its store. Each store only counts the warehouses linked to it, which suits businesses with dedicated warehouses for specific sales channels.
Example: same stock as above. An order for 10 is assigned to Warehouse A and an order for 5 to Warehouse B. Available stock is 90 in A and 45 in B. A store linked only to Warehouse A shows 90; a store linked to both shows 135.
Location-level
This option only appears when you have an active Shopify, TikTok Shop, Amazon, Walmart or Square store with warehouse links. It works like Warehouse-linked, but an order with no warehouse assigned reserves stock only in the warehouses linked to the channel location the order came from, instead of every warehouse linked to the store.
Example: a Shopify store has two locations, Downtown (linked to Warehouse A) and Mall (linked to Warehouse B). An unassigned Downtown order for 10 reserves only in Warehouse A: available stock is 90 in A and still 50 in B.
How do I know which warehouses are linked to my store?
In each of your store's settings, you will see a link to choose warehouses.
This link allows you to manage which warehouses are linked and advertise inventory to your store.
