If your organization uses multiple merchant accounts through the Blackbaud Payment Service, you must mark one as the default to use to authorize and process payments by credit card.
Warning: If you do not mark a merchant account as the default, users cannot save payments when they select to authorize payments by credit card with the Blackbaud Payment Service.
You can also set a merchant account as the default for Card Present transactions. With a Card Present transaction, you swipe the credit card, such as at a ticket booth or gift shop.
