Hi there, Valerieh. I understand that you'd prefer to set up a finance charge instead of applying a late fee.
To do that, you can manually set up and apply Finance Charges or a Late Finance Charge by creating a Product/Service item for a finance charge and then adding it to a new invoice.
Here's how:
- Click the Gear icon at the top-right corner.
- Select Product and Services under the Lists section.
- In the upper right corner, click the New button.
- Choose Service.
- Name your service as Finance Charge or Late Finance Charge.
- Click on the drop-down menu under Income account.
- And select the Processing fees income.
- Hit Save and close.

After setting this up, you can create a new invoice to apply the finance charge.
- Open the invoice page and select the customer who has the overdue invoice.
- In the Product/Service field, select the Finance Charge item you created earlier.
- Enter the amount of the finance charge based on your calculation.
- Set the due date to match your terms for the finance charge.
- Click Save and close.
