If you use our integration with Stripe to collect payments on your OfferingTree site, Stripe will handle transferring money out to you periodically. The first time you receive a payment, it may take 7-14 days to receive your first payout. This is so that Stripe can establish a connection with your bank and ensure that everything is set up correctly. After you receive your first payout, the transfers will have much quicker.
More details on Stripe's payout are here: https://stripe.com/docs/payouts
Additionally, you can also sign in to your Stripe dashboard (https://dashboard.stripe.com/) and review all the payments you have received and the payouts that have been made and that are in progress.
