What is the selling method that involves face-to-face interaction between a sales representative and a potential customer?

The selling method that involves face-to-face interaction between a sales representative and a potential customer is personal selling. This approach allows for direct communication and relationship building, which are crucial in understanding the needs and concerns of the customer. Personal selling often involves detailed explanations of products or services, responding to specific inquiries, and tailoring the sales pitch to the individual customer. The ability to engage directly with potential clients fosters trust and can lead to higher conversion rates, as the representative can adjust their strategy based on the customer's responses and body language.

In contrast, telemarketing involves selling via telephone, which lacks the personal interaction of face-to-face encounters. Online sales occur through digital platforms, allowing for convenience but not personal engagement. Direct mail refers to marketing materials sent directly to customers' homes, which is an impersonal method of communication and does not facilitate real-time interaction. Thus, personal selling stands out as the most effective method for direct, interpersonal engagement with customers.
