Where can I find my invoice number?
You can use your invoice number or order ID on the forms that require an invoice. All of your recent Asset Store purchases can be found on this page with your invoice number and order ID. If your invoice isn’t listed then it is an older invoice number and can be found on the old Asset Store page. You can also contact firstname.lastname@example.org and they can look up your invoice number. Unity does not supply publishers with any purchase information so we are not able to look up your invoice number.
What is your refund policy?
Section 2.9.1 of the Asset Store EULA states that “all sales are final” and we go along with this policy because there is no way to return a digital product.
