As the Marketplace app admin, you can setup the number of days after which your Marketplace app sellers will get their payouts. This setting needs to be done in your Stripe account.
Once you connect your Stripe account, any funds collected via your Marketplace app will get accumulated in your connected Stripe account's balance and will be paid out on a daily rolling basis by default.
If you want to change the default payout frequency, please login to your Stripe account, click on the detail page, click the right-most button in the Balance section, and select Edit payout schedule.
You can now set the payout schedule of your choice which will be applied to all sellers of your marketplace app.
