Courier companies tend to be different from the usual post services. They normally offer better speed of distribution; they additionally give clients more dependability, tracking and the signature of the customer receiving the letter or package. Clearly this is a superior amenity and comes with a increased price than government operated and managed postal services. Governmental postal services may give and compete with courier companies , however this particular individualized service also goes with additional cost as compared to regular postal items. A restriction of courier companies is that they usually do not provide a product for multiple items; clients commonly pay for a single item for a single destination, except where multiple products can be packed into the exact same container destined for a single desired destination. Clearly reports delivered by courier must be more significant and need more speed and security than a regular post item or it might not really justify the additional expense usually applied. There are an massive range of courier providers, from sole-proprietors to family businesses such as Aerospeed Couriers and nationwide and international corporations like Deutsche Post DHL, FedEx, TNT and others. Many courier businesses specialise in a restricted geographic area such as a city or country while others like Aerospeed Couriers have local as well as worldwide businesses. Most courier companies operate in a hub and spoke manner. The largest courier hub in the world is actually at London Heathrow airport. Heathrow offers a fast and fairly central geographical location, which is available to all courier companies with the spokes radiating out to all the countries, towns and villages of the planet. Courier service providers originate from the distant past. In previous days generally there were runners who brought leaders communications of the outcome of battles, such as Marathon. Homing pigeons were also used and acted as couriers even throughout the world Wars. In the past, post riders rushed along posting tracks via post houses to quickly courier urgent materials for their customers.
