Shipping integration with Sage 300

Good Morning Everyone, 

First off Merry Christmas and Happy Holiday! 

We would like to integrate Purolator, FedEx, Canada Post and several other couriers with Sage 300 so the warehouse staff isn't manually entering the same shipping info again into each respective terminals.  We've evaluated Process Weaver (but not much response or follow up support from the company) and ShipStation (doesn't integrate out of the box like would like to). 

I was wondering what other shipping software are available to integrate with Sage300.  Any feedback about them would be much appreciated. 

Thank you in advance.
