In general, ShipperHQ gives fairly accurate shipping dates and rates estimates, providing real-time shipping rates through a variety of different carriers. They also allow custom dimensional rules for one-off, and odd product packaging sizes. -have shipping groups to help streamline the shipping of similar sized boxes or use of free shipping, etc. which has really turned out to be invaluable to my fairly small shipping needs (in contrast to some of their larger clients I mean).

ShipperHQ gives us the ability to create shipping rules based on many different factors such as location, product, customer group, and more. We initially needed to create a surcharge for oversized items that were being shipped to the west coast and this app allowed us to do that easily.

It works for basic shipment packaging prediction.
