The ease of use to pull up quotes from different carriers within my account & compare them side by side.
Also being able to see historical loads as well as upcoming dates is very handy! Pricing can be tricky if you don't have an experienced sales rep who understands MGN's pricing structures vs other companies. This helps avoid costly mistakes that could delay shipments or increase costs in the long run. We're using it primarily for truckload shipping but also do some LTL work which makes quoting easier than trying to find all this info myself.
