Courier Software is typically used by companies that deliver packages by drivers or messengers. Courier Companies need a program to track customers that request a delivery, details about the package, and who will be delivering the package to the recipient. The central person responsible for a smooth transaction is the operations manager or dispatcher. In the 'old days', this was done on a chalk board or white board. Now shipments show up on a single screen, making it easier to follow up on the deliveries.
