In the context of organizational buying behavior, the six buying center roles are crucial in understanding how decisions are made within a company. These roles typically include the initiator, influencer, buyer, decider, gatekeeper, and user. Each role contributes to the buying process in specific ways, facilitating effective decision-making.

The role of an initiator involves recognizing a need and starting the purchasing process. Influencers have sway over the final decision by providing relevant information or opinions that shape the perspective of the buyer. The buyer is responsible for the actual purchasing decision, negotiating terms, and executing the purchase.

While someone in an organization may serve as an advisor or provide counsel during the purchasing process, this term does not correspond to one of the established roles defined in the buying center framework. Understanding these distinct roles helps clarify how organizations make purchasing decisions and the dynamics involved in those processes.
