Hello @MalcolmLiang 

Welcome to the Community Forum

If a customer owes you money, you can write off the bad debt. When you do this, the customer's outstanding balance is removed, your expenses are correctly updated, and any GST liability related to the sale is adjusted.
I have attached this Help Article on Writing off bad debts which will provide the steps to do so.
