Buyer checkout and seller payouts are separate systems.
Buyer payments
Local testing supports bank transfer and cash/collection test payments. Worldpay, Stripe, or PayPal can be connected after hosting, SSL, and merchant approval.
Seller payouts
Seller withdrawals use UK bank transfer or PayPal. Seller requests payout from dashboard; admin reviews and approves manually.
Hold rule
No instant seller payout. Funds become eligible after completed order status plus the 7 day hold period.
