We have received tons of requests for invoices/statements from you guys. Tons! So we have abandoned our old model of email receipts and have replaced it with a more statment-ey one.
If you go to your account then you will find a box to input your organization. Once your payment goes through we can send you an email with your Statement in it. It will display all of the information that you could need in order to get your money back from the higher-ups at your place of business.
Good luck collecting, Stackers! Let us know if you have any other feature requests.
