Quote to bill to receipts

As a small service contractor I wanted this to work but used up my 10 free transactions trying to figure out how to start with a quote that was not marked paid in full. They should offer a trial mode where you can send any number of email quotes, invoices, and receipts to yourself so you can figure out how this works. Could be a lot simpler or intuitive.
