The organizer is responsible for setting up the available payment methods and the payment period. He can choose between Paypal, credit card (MasterCard/VISA) and bank transfer.
The payment method bank transfer is going to be deactivated some days before an event starts, because all payments have to be received before the start of an event and that's not guaranteed, if you transfer the money a few days before the start. Bookings which are not paid on time can be cancelled in agreement with the organizer.
Payment with direct debit and with american express/ discover credit cards is possible. Just choose paypal (even if you don't have a paypal acccount) as payment method on the booking website. You will be redirected to paypal, where you can enter your direct debit or credit card information without creating an account.
Please transfer the open invoice amount in a timely manner to the bank account which is mentioned in the payment request. The registration process is only finished after the receipt of payment. doo sends reminders at regular intervals until the payment has been received.
Before that your slot is just reserved.
If your booked event is set far in the future and you want to pay at a later time, please contact the organizer.
