If a temu stock order is overdue, it may cause some of the following problems:

1. Delayed delivery: Overdue means that the order cannot be delivered on time, which may cause inconvenience to customers and may affect their business plans.

2. Unsatisfied customers: Overdue delivery may cause unhappy customers because they may have planned to use the goods and now cannot get them on time.

3. Damaged reputation: Overdue delivery may damage your reputation and credibility. Customers may question your delivery ability and reliability, which may affect your future business relationship with them.

4. Penalty or liquidated damages: Depending on the terms of the contract, overdue delivery may result in the payment of fines or liquidated damages. This may increase your costs and have a negative impact on your financial situation.

To avoid these problems, it is recommended that you try to stick to the delivery date of the stock order and keep communicating with your customers to explain any issues that may cause delays in a timely manner and try to provide solutions. If it is really impossible to deliver on time, negotiate with the customer in a timely manner and seek their understanding and support.
