Usually, invoices are sent to the email address attached to the account which generated the payment, immediately after the purchase is confirmed. You can also find and download a copy of your invoice in the Classroom application, on the Billing page (after the payment if finalized, you will be able to access your Receipt instead of an invoice).
If you have not received the invoice, have any troubles downloading it or cannot find it on the Classsroom app, please contact us (with details about your purchase) and we will help out.
We can sometimes accommodate generating invoice previous to a purchase being made through our applications (i.e. creating/updating a team). However, we do insist on the account owner to follow the required steps through the application as it is the only way to correctly create (or upgrade/renew) a team and update its information in our database. Thus, any future issues, like incorrect team constraints, unmarked payments or accidental block, will be avoided.
For any issues, questions or concerns regarding payments, please contact firstname.lastname@example.org to settle the matter (providing detailed information about your payments will help towards a faster resolution).
