The explosive growth of e-commerce, along with the trend toward distributed warehousing, has fundamentally changed how companies ship products. In particular, there has been a shift from shipping in “bunches” (full truckload or container load) to shipping in “eaches” (primarily through parcel). While historically an afterthought, parcel has become a bigger area of focus for shippers, and shippers are increasingly using software and systems that automatically select carriers based on cost, speed, and service. The growth in these systems has been very rapid in the last several years, due to the very short time to breakeven and overall ROI associated with these systems. Shippers, particularly parcel shippers, need software and services to significantly reduce shipping costs, make better shipping decisions with more flexibility and visibility, and synchronize shipping processes across multiple shipping locations.
