After you have made a payment, an invoice is generated automatically. You can download your invoices by navigating 'Settings > Billing > Invoices (from the top)'.
Please do note that invoices are available only for users with administrative rights and users with editor roles can not access them.
If you are looking to pay with a bank transfer, then please do contact our support team before making any payments so that we can issue a correct invoice. Please do not use your previous invoices or any information from them for new bank transfers.
