How do you record reimbursable mileage so you can add it to an invoice?

Add a line to the customer invoice and choose Mileage in the Product/Service cell. Use the QuickBooks Online mileage feature to record miles driven and mark them as billable to a customer.

Create and pay a bill that includes the reimbursable mileage assigned as billable to the customer. Add a line in the Category detail table and choose the Mileage expense account.
