I'm looking for an app that will sync my Shopify inventory to Amazon. I tried Sellbrite but the issue there is that it uses Sellbrite as the primary "channel" for inventory. This wouldn't be an issue but I enter all of my orders manually into Shopify from Amazon because I like the reports and also use it for custom packing slips. This causes inventory to be deducted twice when I receive an order. I asked if they were able to switch off orders from a certain channel but that wasn't possible.
Are there any apps which simply detect the inventory in Shopify and sync it with Amazon?
