There are many training courses to improve employees' sales ability. I suggest you do the following training. First, enterprise training can only be completed by the boss himself. Only when you have established confidence in the enterprise can you have confidence in the products, otherwise the salesman will not dare to speak loudly. Second, the product knowledge training for employees is jointly completed by the product research and development department and the marketing department. Only when you are familiar with your own products can you understand the characteristics of your products and say it in your own words. Third, the best way to train sales skills is to let employees enter the market and attend the training with problems. Such training can be conducted by some business friends and trainers. Only through actual combat can we understand the importance of skills more deeply.
