Hey Chris, I’m one of the people behind SKUSavvy, which might be what you are looking for. It’s a warehouse and inventory manager with order fulfillment and shipping built-in to be a modern version of the classic WMS out there which is made specifically to Shopify.
To you points:
- Tracks real-time inventory: yes, it will track orders/inventory across platforms (all, except Reverb currently) with central visibility into the position of items within the warehouse on a visual layout
- We would hold individual orders information to sync back up to Quickbooks, however, the breaking down of orders on Shopify would likely be a Quickbooks App specifically. We can do UOM and kitting for breaking down orders that way.
Likely can make something happen, let’s jump on a call if you’d be open to discussing further - calendly.com/skusavvy
