Mojo Boutique

we use it mainly for inventory and order synchronization (not for product setup and listing integration). For us the app works fine. Support is readily available. I like it that I receive Email alerts, when an order doesn't synchronize, so I can address the issue immediately and the customer gets the product within the promised delivery time.

It helps me a lot, It fulfilled my requirement as I'm expecting. I suggest you to try this app. It may fulfill yours too..
