The most important thing you need to know at this stage is that the plugin supports two file formats - XML and CSV.
When you get a link to an XML or CSV file from your provider, paste it into the field visible in the photo and import it with one click. Sounds simple, right? And it does! :)
If you want to import a file from FTP or add a file directly from disk, use the FTP Import for Dropshipping XML WooCommerce add-on.
