As an independent courier, your duties are to pick up, transport, and deliver documents, supplies, and packages. Some independent couriers make their deliveries via bike while other workers drive cars, vans, or delivery trucks. As an independent courier, you typically contract with your clients directly, rather than working through a courier service, although some couriers also find work through online services or job boards. To be an independent courier, you must have your own vehicle or another reliable method of transportation.
