Any product or service may become a complex sale. In some instances, a complex sale occurs when the market is mature and the stakes are high enough to warrant attention from a variety of stakeholders in the buying organization. In other instances a complex sales process is needed when the buyer has never had experience with the vendor, technology being sold, or if the solution is business critical or impacts the buying organization on a strategic level. The series of filters, purchasing steps, and stakeholders involved are designed to reduce the risks associated with making the wrong buying decision.
