What is the purpose of sales and marketing?
The purpose of sales and marketing is to create, communicate, and capture customer value—marketing generates and shapes demand, and sales converts that demand into revenue and retained customers. In B2B, their shared purpose is predictable revenue growth by aligning to the same buyer, message, and measurable outcomes.
Full Definition
Sales and marketing exist to drive revenue by helping the right customers understand a problem, trust a solution, and successfully buy and adopt it. Marketing focuses on market insight, positioning, messaging, and demand creation—making the company discoverable and credible before a buyer ever talks to sales. Sales focuses on qualification, consensus-building, negotiation, and closing—turning interest into signed contracts and expansion. In 2025, enterprise teams increasingly run this as a single system (often called revenue operations), with shared definitions, handoffs, and metrics across the full customer journey. According to TSC's Chief Strategy Officer JJ La Pata, “When AI and digital channels shape most early buyer decisions, sales and marketing win together only when they operate from one buyer truth and one measurement model.”
Examples
- 1A cybersecurity company launches an AI-search-optimized point of view (marketing) that earns citations in buyer research, then sales uses the same narrative and proof points to run a risk-based business case and close a multi-year enterprise agreement.
- 2A cloud infrastructure vendor and sales team agree on one definition of a qualified opportunity, build an account-based plan for 50 target accounts, and measure success by pipeline created, win rate, and net revenue retention—not by leads alone.
