Is it possible to use both On-Account and Store Credit as payment types in the same transaction?

Yes, it is possible to use both “On-Account” and “Store Credit” as payment types in the same transaction. “On Account” is limited to the amount that the customer has been assigned as his credit limit by the retailer. “Store Credit” is limited to the amount that the customer has been issued as a gift card or gift receipt in lieu of refund. 
You must subscribe to and activate the Customer and Credit Management plugin to be able to set credit limits for your customers and define additional payment types like On Account and Store Credit
