Inventory sync helps you save time controlling the stock levels of your products across multiple channels, all in one place!

  • Full control - select the specific channels & products that you wish to synchronize

  • Bulk updates - update inventory levels in bulk (eg. via csv file)

  • Automated process - inventory sync runs 24/7 regularly updating live listings

  • Regular updates - sync are initiated every 1-10 minutes to ensure rapid and continuous coverage and control of your stock levels

  • No more overselling - when an item sells, the quantity for all associated listings across all channels and sites gets updated to prevent selling more than you carry


Product SKUs
In order to enable Inventory Sync, every listing must be set up with a unique SKU code. SKUs (stock keeping units) are used internally, allowing you to identify, track and control your inventory.

A SKU can be made up of any combination of letters and numbers.
For example, many sellers create SKUs systematically to identify the item
location in the warehouse, or to organize items by product group or purpose.

If you sell a certain item on multiple channels or sites, setting the same SKU to all relevant listings for the item will allow you to control the stock level in bulk.
