What Are B2B Buying Groups?

A B2B buying group (also called a buying committee) is a group of individuals within an organization who collectively participate in the purchase decision-making process. Depending on the deal size, industry, and complexity, a buying group may include anywhere from three to fifteen stakeholders—each with unique responsibilities, pain points, and evaluation criteria.

Unlike B2C, where a single person makes a purchase, B2B decisions are collaborative and risk-driven. Stakeholders conduct research independently, compare vendors, evaluate ROI, and collectively determine whether a solution aligns with business priorities.

Trends influencing the rise of B2B buying groups include:
