1 is just a way to divide customers into big customers and small customers. This method is usually of little use to salespeople. For example, although some customers are big, they have no sales opportunities. Strictly speaking, they are not customers, so first you have to forget the size of your customers.
You can divide customers according to the feasibility of possible transactions, such as initial contact, business opportunities, contract negotiation, contract payment, construction and after-sales service, and arrange the time reasonably according to different stages, so that you can always pay attention to the customers negotiating contracts and pay close attention to the customers with business opportunities, so that you can reasonably divide the time.
Especially for customers with business opportunities, we must make a reasonable evaluation, on the one hand, the authenticity of this opportunity, on the other hand, we must correctly evaluate whether this opportunity belongs to me. For example, some companies want to buy a set of equipment, but they are designated to use foreign brands. At this time, there are basically not many opportunities for domestic enterprises. At most, they are familiar with each other, and there is no need to invest more energy.
What you said before is basically just the stage of finding sales opportunities. Selling is actually playing with probability, casting a net all over the sky, looking for opportunities and then analyzing what I can catch. Once I find such an opportunity, I will never give up.
Hard work will definitely pay off. I wish you success!
