Ha, i've done something similar. It's dirt simple , you put total price and categories / tags in the subject of the email ( because you are much more accurate than any OCR, and doing 1 receipt at a time it's not even noticeable work ), and attach a picture/pdf or the expense. then i have a ruby script which connect to the imap account, creates reports based on sender and tags, including attachments in the breakdown. Simple and effective.
