Third party logistic companies have been growing in popularity since the 1980's. Their popularity arises from their uncanny ability to manage distribution networks; a task that was previously performed by manufacturers and producers. By hiring a 3PL company to handle their day-to-day logistical operations, businesses are free to focus on their core competencies. Third party logistic providers offer services such as sorting, packaging and repackaging, inventory management, order entry and fulfillment, labelling, light assembly and price labeling.
