How often does Stripe payout to my bank account?

Once you start processing with Stripe, your first payout is made 7-10 days after your first successful payment is received. Subsequent payouts are then processed according to your account’s payout schedule. This allows Stripe to mitigate some of the risks inherent in providing credit services.  Your money is therefore usually about 7 days after the purchase. 

Many of our organisation's change their Stripe payout settings to manual and use their PTA Events "Treasurer by Event" report to payout specific amounts to their bank account.
