Billing & History tab under your Account Page
Your subscription invoices and credit top-up receipts are listed here. Each row includes a direct link to the invoice and your full payment history.
Email receipts
Receipts are automatically emailed to your registered address after every successful payment, both for subscription renewals and credit top-ups.
Custom billing address
If you've set a custom billing address in Account Management, invoices will be sent to that address instead of your default registered email.
