Please confirm that this is the case: ShippingEasy cannot proactively send quantity updates to Ebay or Amazon until an order for that SKU has come from that marketplace. If we've had an order for a SKU from Ebay but not Amazon, then ShippingEasy can control that SKU on Ebay but not Amazon.
It seems like it will take a fatal number of order defects before ShippingEasy is able to actually manage our inventory across Ebay, Amazon, and Shopify. I feel like I must be misunderstanding how this works. Please advise.
