When ordering a subscription extension for Timebutler, you can choose from several payment methods:
Payment by SEPA direct debit, bank transfer, PayPal, or credit card
You order the subscription only once. After that, we automatically collect the amounts and provide the invoice (to download or sent automatically by email).

Please note: the bank transfer (invoice) payment method is only available for a usage period of 6 months or longer. Make sure the billing information is completely filled in under Account balance > Account balance > Edit details.
