Sales and marketing requires planning, execution, and persistence to close deals. The three-tier approach of plan-execute-win is effective for new salespeople. It is important to listen to understand clients' needs, build close relationships over time, and provide true value at a fair price to seal deals. The steps to making a sale involve prospecting potential clients, conducting an interview to present your product and engage the client, and closing the sale by addressing any objections. With preparation, confidence, and responding thoughtfully to doubts, salespeople can advance their presentations and close more deals over time.
