You can pay by credit card, bank transfer or PayPal. For credit card, click the green "online payment" button on your invoice. For Paypal, click the same green button on the invoice, and choose "PayPal" instead of "Credit Card", and follow the prompts. For bank transfer, your invoice has the details of the bank account to transfer to.
Note that monthly payments can only be paid by credit card (Mastercard, Visa, AMEX or JCB). We do not charge any credit card any surcharge fees. For Annual payments we also accept bank transfer and PayPal payments.
