ShipStation's Inventory Sync feature eliminates the need for manual inventory updates, ensuring your inventory levels are always accurate and up-to-date. Once you have activated Inventory Sync in the Add-On section of your account settings, you can easily manage your inventory across multiple platforms, saving time and reducing the risk of errors.
ShipStation supports synchronizing inventory across these supported selling channels: Amazon, BigCommerce, eBay, Etsy, Shopify, and Walmart. More channels coming soon!
When syncing available inventory counts, you can select which sources to sync inventory from and determine which target stores should receive updates.
Sources are where you want to pull inventory stock level into ShipStation. Sources can be ShipStation Inventory or ShipStation 3PL.
Targets are where you want stock levels to be updated from the source. Targets can be Amazon, BigCommerce, eBay, Etsy, Shopify, or Walmart stores.
You can select as many Sources and Targets as you'd like.
Accurate, up-to-date inventory is essential to keeping your business running smoothly. Inventory Sync can help you:
-
Save time: Remove the need to manually upload inventory CSVs and inventory levels by letting ShipStation automatically sync your inventory levels from your selected sources.
-
Reduced risk of errors: Reduce the chance of errors by eliminating the need to manually update inventory levels on each sales channel.
-
Stop underselling and overselling: Never miss out on a sale because a product is incorrectly listed as “out of stock” at a store or marketplace. Underselling directly leads to missed revenue in the short term and lost customers. Conversely, avoid costly mistakes from canceled orders by incorrectly listing an item as being "in stock".
-
Stay in good standing with marketplaces: Inventory Sync ensures your inventory is always up-to-date and accurate across all your sales channels. This means you won’t upset customers with unfulfillable canceled orders and won’t risk being suspended by marketplaces like Amazon, eBay, and Walmart.
-
Inventory Tracking enabled. ShipStation must be aware of your initial inventory levels and whenever a restock takes place.
