Customers (the other party is the boss) like to default on payment. Is there any way for him to settle accounts immediately or monthly?

There seems to be no practical way. It may depend on the strength of both sides. It's the first time to do business with each other, it's best to do it now, and then consider monthly settlement after building trust with each other. If you really want to be this customer, try to convince him that I have never done business like this, which is unfair to other customers. Now everyone else has done it, or worst of all, we have to do business here. I hope he can understand. Look at the attitude of customers. If it still doesn't work, say I'm just a salesman. The company's system has always been cash settlement and monthly settlement. There is no settlement method like yours. It's really hard for me to explain it according to your method. Do you think you can bend the rules and settle accounts at least once a month? No more, we can only persuade him to give a deposit first and then calculate how much it will sell later. If you can't do it again, you can only let him check it completely. Old customers with high risks are generally settled on a monthly basis. I don't know. Is that okay? Talk more about the difficulties here and make each other more considerate. I want to know if this has any effect, so would you please deal with this matter and tell me the result?
