You may wish to submit your Academia Premium purchase to your department or institution to have it reimbursed, or simply wish to have a receipt to keep track of your expenses.
If you paid with a credit card, you can enter in your receipt information, such as a billing address or VAT, on your Academia Premium settings page by selecting "Enter Billing details."
If you did not get a receipt for a payment and you would like a receipt for that payment, please contact us and your Academia Premium email with a request for a receipt.
If you need a payment invoice that includes additional information, such as VAT information, please contact us with your Academia Premium email, your billing address, VAT or tax ID, and anything else required. We'll be happy to generate that for you.
