Strategic Account Management (SAM) is a strategic approach used to ensure the long-term development and retention of major customers. It provides a means to develop and nurture relationships with strategic customers. SAM requires developing deep understanding of customers' businesses and tailoring long-term product/service offerings to their specific needs, with the goal of developing collaborative partnerships. Effective SAM involves selecting and categorizing the most important customers that are aligned with the company's strategic vision, then developing individual multi-year strategies and relationships with each.
