I need help, I'm new with quickbooks. We are a rental house company. We invoice clients on a per-qty-per-day basis. For example, a client rented 2 cameras for 2 days. If our price for the camera is $50 per qty per day, total invoice amount should be $200 for 2 days rental. How can I make the invoice showing the Qty x Rate x # of days Rented?
