The activation depends on the payment method you chose when booking. PayPal usually processes faster than a bank transfer.
This guide is for you if you have booked and paid for Premium but still see an outstanding invoice.
With PayPal, Premium is usually activated after the payment is confirmed. For bank transfers, activation happens after the payment is received and matched.
A bank transfer often takes 1 to 3 business days. It’s important to use the correct payment reference so the payment can be matched. If you have paid and still see an outstanding invoice after a few business days, use the "Already paid?" option on your order.
