Sellers on a domain that is payment enabled, can see the feature under 'Orders' tab. There will be 2 sub tabs > 'Payment Terms & Methods' and 'Payment Gateway'.
Sellers can open 'Payment Terms & Methods' and setup the options for buyer order placing & seller order placing. Multi-select options are possible for payment methods for both buyer/seller order placing .
Single select option will be enforced for Buyer order placing > Payment Term. Multi-select will be possible for seller order placing > Payment terms.
Selecting 'Save' button, saves the setup.
When a payment method that requires a payment gateway is selected, UI displays gateway setup button. Seller can either press the button or select 'Payment Gateway' tab to setup payment gateway. We offer 3 gateways > Authorize.net, Stripe & Paypal Pro. Only one gateway can be setup at a time. If you wish to delete that setup another gateway, you have to remove the existing gateway.
