On the web version you may check your customer transactions at Reports > Transactions. The next screen will display a customer list then you may use the search box and click on the customer.
When you click on the client, you will see the orders. Now you may sort by a date range and create the PDF. Clicking on the payment brings you to the confirmation payment and the order as well. That is when you click on the orders number.
