I've got the steps you'll need on how to fix this, rigsbee-rick4.
QuickBooks offers two ways on how to handle the late fee. You can either create a second invoice or add the fee line item to the existing invoice. I'll show how to accomplish the tasks:
To create an invoice with an additional fee:
- Go to + New and select Invoice.
- Fill out the invoice with the necessary information.
- From the Product/Service drop-down, choose the late fee item. Please note: If you don't have an item for additional charges, select Add new from the Product/Service item drop-down. Choose the appropriate type, then fill out the Product/Service information form.
- Enter the amount of the fee.
- Click on Save and close.
To add the fee to an existing invoice:
- Go to the Sales tab and select Customers.
- Choose the name of the customer.
- Locate the invoice.
- In the next unused line on the Product/Service section, choose the late fee item.
- Enter the amount.
- Click on Save and close.
