Each time a donation is made, it goes through a verification process before it is available for transfer. Your transfers will include all of the donations available at the time, so if it looks like you are missing funds, it is likely that the donations are still processing. Processing times depend on the card provider for each donation and can vary from 1-2 business days to potentially up to 14 business days.
You can see pending donations in your transfers overview under "Donations still processing."
Your “total raised” will be the total amount raised on your fundraiser, minus transaction fees (which include debit and credit charges). You can click the green “fees” button above your total raised to view a breakdown of your fundraiser’s fees.
