Funds acquired from card payments are available for Instant Payouts as soon as the charge is complete. ACH or bank debits are only available for Instant Payouts after the payment has settled.
Stripe charges Dashboard users a 1% fee for all Instant Payouts for CA, EU, UK, SG, and NO, and a 1.5% fee for US, AU, and NZ. Each Instant Payout transaction has a minimum and maximum amount dependent on the currency.
