Hey @kellyr2, great to see you again. We can have this done with some easy steps.

If the invoices you send in QuickBooks become uncollectible, you can record them as a bad debt and write them off. This way, it ensures your accounts receivable and net income stay up-to-date. Here are the steps to write off invoice balances.

To start, create an expense account and create bad items as a placeholder for the unpaid invoices. 

Next, make a credit memo and apply it to the invoice. Follow these steps:

1. Go to the + New button.
2. Click Credit memo.
3. Select the customer from the Customer ▼ dropdown.
4. In the Product/Service section, select Bad debts.
5. Under the Amount column, enter the amount you want to write off.
6. And in the Message displayed on the statement box, enter Bad Debt.
7. Select Save and Close.

These are the steps to apply the credit memo to the invoice:

1. Go to + New.
2. Under Customers, select Receive payment.
3. From the Customer ▼ dropdown, select the appropriate customer.
4. Under the Outstanding Transactions section, select the invoice.
5. From the Credits section, select the credit memo.
6. Select Save and Close.
