The distribution channels are called the course of the product or service from the manufacturer to the consumer. Every mediator who brings the product closer to the consumer represents a level of the channel. The zero level channel consists of the manufacturer and consumer, the first level channel consists of one mediator and the second level channel consists of three mediators. Using a mediator brings a higher efficiency in the delivery of the product to the wanted market. The manufacturers differ by the skills of managing distributers. The cooperation within the channel conditions effective channel business. In order to make cooperation the manufactures use the force of coercion, reward, legal force, professional force and referential force. By cooperation within the channels one gets a successful and efficient channel, which achieves its goals and specific goals of the members of the channel. For a successful cooperation communication and equal distribution are very important. Where there is an equal goal there is better cooperation between the members of the channel. Success and effectiveness of the channel can be a good assumption for bigger market competitiveness. In order to create a more efficient channel, the manufactures and mediators merge and create an integral system of marketing channels. A long time partnership is important for efficient functioning of the channels. By better cooperation the members of the channel can have a better understanding and service for the targeted market. Although the members of the market are codependent, they often work alone for their own short term interests. Disagreements concerning goals, roles and rewards often lead to conflict within the channels.
