To use CLV to evaluate your sales team's performance, you need to track and analyze the CLV of the customers they acquire and retain over time. Utilizing a CRM system or spreadsheet can help you collect and organize the data. To do this, calculate the CLV of each customer using the formula that best suits your business model and data availability. Subsequently, segment your customers into groups based on their CLV, such as high-value, medium-value, and low-value customers. Assign each customer to the salesperson who acquired or retained them, and calculate the average CLV of each salesperson's portfolio. Then compare this average with that of the entire customer base and the cost of acquiring and serving them. Identify which salespeople have the highest and lowest CLV in their portfolio, and analyze the factors that influence their performance like sales skills, customer service, product knowledge, and market conditions. Finally, provide feedback, coaching, and training to your sales team based on their CLV performance, as well as set goals and incentives that align with your CLV strategy.
