Hi @jennfr00,

Thank you for posting here in the Community. I can provide information on how you can handle the remaining balance due of the invoice in QuickBooks Online.

You may have small balances that are the result of an underpayment. It would cost more time to collect or pay the amount due than it would be to clear it from your accounts.

We call this Bad debt which refers to a customer that owes you money, but you can't collect it. When invoices you send become uncollectible, you need to record them as bad debt and write them off.

It ensures your accounts receivable and net income stay up-to-date. You'll need to create an expense account, a credit memo to clear the invoice balance, and a non-inventory item for bad debt.

To create a "bad debts" expense account, please follow these steps:

1. Click the Gear ⚙ icon in the upper-right corner and select Chart of accounts.
2. At the upper right, select New to create a new account.
3. From the Account Type ▼ dropdown, select Expenses.
4. From the Detail Type ▼ dropdown, select Bad debts.
5. Hit Save and Close.

Once done, you can proceed with creating the non-inventory item for bad debt. Go to this link and follow the remaining instructions starting from Step 3: Write off bad debt in QuickBooks Online.

Also, there are many ways to customize your reports. To learn how to filter and show specific accounts, customers, and layout format, check out this article: Customise reports in QuickBooks Online.

Don't hesitate to get back anytime you need assistance performing the Write Off process in QuickBooks. I'll keep an eye on your response. Take care.
