The number of sales is the most important factor in a business. To increase sales, we need to find out the reasons for the stagnant number of sales and solve them. First, we must find out why customers don't buy from us. They may not know how much our products are worth. We can solve this problem by increasing advertising and publicity. The second reason is that they are unfamiliar with our brand or company. We can solve this problem by introducing ourselves and making long-term cooperation with our customers.
