Hey Jason,
You are in luck! There is an app that should be able to help you out. It's called Stitch Lab. Here's what they had to say about it.
Imagine you just made a sale on your Shopify store.
In minutes, Stitch automatically updates the inventory levels in Shopify and any other sales channels you have specified. Reduce the risk of overselling your products.
Seconds later, that sale (including all buyer information, listings, addresses, payments, and more) are automatically built in Stitch.
Compare and analyze sales data from this sale and sales across all of your sales channels to make smart business decisions with easy-to-read reports.
Hope this apps meets your needs!
