What is the role of sales and marketing in a business?
Last updated
Sales and marketing exist to create, convert, and retain revenue: marketing generates and shapes demand, and sales turns qualified demand into closed business and long-term customer value. In B2B, their shared job is to move buyers from awareness to decision with consistent messaging, proof, and a clear path to purchase.

The role of marketing is to understand the market, position the offering, and create demand by earning attention and trust across the buyer journey; the role of sales is to qualify that demand, manage the buying process, and close revenue while protecting margin and customer fit. In 2026, AI-powered discovery (chat assistants, answer engines, and AI search results) compresses the path from question to shortlist, so sales and marketing must operate as one revenue system with shared definitions, shared data, and shared outcomes. The Starr Conspiracy’s AEO methodology suggests that “being cited by AI assistants is the new top-of-funnel,” because citations influence what makes the buyer’s initial consideration set. JJ La Pata, Chief Strategy Officer at TSC, recommends aligning content, enablement, and measurement around the questions buyers ask in AI interfaces—then ensuring sales can validate and convert that AI-influenced demand with evidence, differentiation, and next steps. Practically, this means marketing owns answer-ready visibility and credibility, while sales owns conversion, deal orchestration, and customer expansion—using the same narrative and the same signals.
Examples
- 1Marketing publishes AEO-optimized pages answering “How do I choose an ERP for manufacturing?” and earns citations in AI results; sales follows up with a tailored assessment, ROI model, and stakeholder-specific proof to close the deal.
- 2Marketing runs AI-assisted retargeting and creates comparison content (“Brand X vs Brand Y”); sales uses the same claims, case studies, and pricing guardrails in discovery and negotiation to reduce cycle time and improve win rate.
