Do you need a receipt from one of your projects? You can easily do this via the homepage. Mouse over the "Account" header, and click on "Transaction History".
This will take you to a list of all your payments towards projects. On the right side is the "Receipts" column. From there you can easily print any of your past receipts. The gif below illustrates this process.
