When a client confirms an order there are 2 emails sent.  The first is sent to the client, and optionally cc'd to you, and contains basic information on the order - total price, shipping charges, etc.  The other email is sent to the email address set under Options -> Company and contains a PDF file with the client's order.

The top of the first page contains basic information on the order.  The left side has the invoice number, date or order, order status (New, Complete, Paid, Canceled), shipping option, total price, tax charged, shipping charged, and the total billed.  The right side contains the buyer information - name, address, phone number, email address.

This file is also available through the admin interface by selecting the order under the Orders tab.  About halfway down the page is a heading "Items Ordered" with a small PDF icon that will load the PDF order page for you.

There is also an example of the order PDF available.

Pro vs. Lite version

You'll notice that the sample has "ProofBuddy Demo" across the top of the page.  This will be whatever you have entered as your company name under Options -> Company.  It's just that for my development version I'm using ProofBuddy Demo as the company name. 

If you are using the Pro version of ProofBuddy you will also have the option to upload a graphic that will be used in place of the text.
