AccountEdge Pro Requirements To Use Shopify
To link your Shopify web store to AccountEdge Pro 2018, you'll need to be using AccountEdge Pro 2018 or later. Shopify changed how applications link to stores so the latest version will be required.
There are also changes to how Shopify handles inventory levels that will become required by July 1st 2018. In order to sync inventory levels you will also need the 2018 version of AccountEdge with the latest updates installed.
