You can connect your store to Inventory Planner even if we don't have an automatic connector for your e-commerce platform. In this case you need to prepare your data in the special TSV/Excel format on your side and make it available via a Dropbox or a web server.
We will sync this data automatically on the daily basis, so by keeping it up to date on our side you will have the latest data in Inventory Planner.
