FunRaisen does not charge your card until the campaign of the participant you are sponsoring is considered closed. In the pledge per challenge model, participants are continually completing tasks over the course of time set by the admin for the campaign. Rather than have potentially dozens of micro charges to your card over the course of the campaign, we track all activity of the participant you sponsored and make a 1-time charge for the total donation amount at the end of the campaign. As an exception, when making a flat donation either to the participant or directly to the campaign, the card is charged at that time. If you have any questions regarding payments or charges, please contact a FunRaisen representative via email at support@funraisen.com and we will gladly assist.
