Amazon, eBay, Etsy — Salestio

The app helped us sync orders from Amazon to Shopify. It also sends the tracking information back from Shopify to Amazon which is very helpful. The support is great and they helped us solve all of our issues, moreover they reply to our emails very quickly. So if you are looking for an app to sync orders between Amazon and Shopify, then I highly advice to try this one out. Lastly it also works for all of the marketplaces on Amazon.
