Unlike many other crowdfunding sites, you don’t have to wait until your campaign ends before accessing your donations. This graphic sums it up:
Donations received via Stripe are automatically sent to your bank account on a 7 day rolling basis. So if a donation was made on March the 1st. it may be deposited into your bank account on March 8th, sometimes Stripe does it much sooner. After you have received your first payment, Stripe will enable daily payments to your bank account.
