Hi Nicholas!
We’ve just created a tool for Shopify which can help you to solve the inventory management issues — Shop Sync.
It pulls in your all of your product variations from multiple sales channels and allows you to manage them in a single location.
Currently multiple Shopify stores are supported, but in the next coming weeks, we plan to add support for Etsy, Amazon and Ebay as well.
Shop Sync has a built in search function that makes it fast and easy to navigate through all of items by name, quantity, product type and sales channel.
After you’ve made your inventory adjustments — the App syncs all the changes directly to Shopify.
The application is currently free to install, so you can play around with it at no cost.
