Invoices can be accessed for any paid order made on Zenva Academy upon completion of the transaction for that order - even for recurring payments for our subscription service.
Please note, though, that invoices will generate with whatever billing address is currently set for your account. If you'd like to change existing billing/invoicing details, please see this article: How can I change the billing details for my account?
