Keeping track of inventory for your Jet.com listed products using ShipStation's Native Inventory Management solution is required for the integration. ShipStation must be the source of truth for your inventory counts of Jet listed products.
ShipStation uploads inventory counts from your ShipStation Inventory Warehouse to your linked Jet Fulfillment node. Make sure to link a ShipStation Inventory Warehouse to your Jet Fulfillment Nodes.
If you do not have a ShipStation Inventory Warehouse linked to a Jet Fulfillment Node, ShipStation will upload a stock count of zero for your SKUs to Jet.com and you will not receive any orders in ShipStation.
Set inventory stock counts for your products using ShipStation's Inventory Management solution and ShipStation will upload the stock counts to Jet.com for your listed products automatically once a day.
