Cross-selling involves offering a customer additional products or services that complement, relate to, or logically follow from a product the customer has already purchased.

CRM technology supports cross-selling by integrating transaction histories with customer profiles and product relationships. Analytical tools can identify products commonly purchased together, detect customer preferences, and generate personalized recommendations. Effective cross-selling can increase customer lifetime value, raise average order value, improve utilization of existing customer relationships, and generate incremental revenue without requiring the organization to acquire an entirely new customer.
