There is no consequence if you do not meet your fundraiser goal. Funds are collected to your chosen payment processor account as they are donated.
For WePay users, your donations, less WePay's online processing fees, will be automatically withdrawn to your bank account or sent to you by check on your chosen remittance schedule. If your fundraiser uses PayPal instead, your donations, less PayPal's processing fees, will post to your PayPal account balance as they are received. You can then log into PayPal.com at any time to withdraw the funds to a bank account.
Please note, due to GoFundMe's recent acquisition of YouCaring, all fundraisers will automatically stop receiving donations on May 31, 2018 or on June 31, 2018, depending on your location. For more information, please see this page:
