Yes. The credit card or payment method you established will automatically be charged every month. That way you don't have to worry about mailing a check.  After setting up your donations in the donorbox module, you will receive an email that will allow you to log in to your donorbox account. In that account, you can manage your donations and add a new payment method if your card expires. If you have any questions about the payment process, please refer to donorbox's help article.
