Sales leads are potential customers who have shown interest in a company's products or services. They can be generated through various methods, such as online inquiries, referrals, or marketing campaigns. Identifying and nurturing these leads is crucial for businesses to convert them into paying customers. Once a sales lead is identified, the sales team typically engages with them to understand their needs and preferences. This process often involves follow-up communications, such as emails or phone calls, to build a relationship and guide the lead through the sales funnel, ultimately aiming for a successful transaction.
