To replace your bank account or credit card, first set your payment method to manual in our dashboard: https://my.tilaa.com/payments/recurring
You will now have to fulfil your next invoice manually, at which you can specify your new payment details. During the payment process, you can enable recurring payments for your new bank account or credit card if you desire.
If you don't want to wait until the next invoice has been sent, you can add an amount of credit to your account directly. This credit will be used to settle your next invoice: https://my.tilaa.com/payments/process
