First of all, we should analyze why the other party doesn't give you the payment, because of the quality of your products or services, or because the other party has maliciously breached the contract or the other party really has no money.

Second, we should take corresponding measures according to different situations. If it is your own problem, you should sincerely apologize to the other party and ask the other party to pay back the money in time on the basis of solving the previous problem through consultation. If it's the other party's problem, you should consider using goods to settle the account, or paying off your debt by clearing the triangular debt. If it is a malicious debt, it depends on the amount. If the amount is large, you can consider suing for settlement, but you must pay attention to collecting relevant evidence. The most important thing is not to pass the prosecution period. If it passes, you'd better ask the other party to come up with a recent repayment plan or something, which can be used as evidence.
