What kind of sales technique includes upselling and cross-selling?

The sales technique that includes upselling and cross-selling falls under revenue management. Revenue management focuses on maximizing a company's revenue by understanding consumer behavior, optimizing product pricing, and leveraging different sales techniques to enhance the overall profitability of services or products offered.

Upselling involves encouraging customers to purchase a more expensive item or upgrade their purchase, while cross-selling suggests additional products or services that complement the customer's initial choice. These strategies are directly aimed at increasing the average transaction value and overall revenue.

In contrast, the other options, such as direct marketing, public relations, and sales forecasting, do not specifically encompass upselling and cross-selling techniques. Direct marketing targets potential customers through direct communication, public relations involves managing the public image of an organization, and sales forecasting is concerned with predicting future sales figures based on past data and market trends. None of these directly relate to the techniques of maximizing sales through additional or upgraded purchases.
