It's not necessary to include a card on your transaction, though it's recommended if you regularly do business with this person or company, since it can make your reports more accurate and complete. You may not need to create cards for one-time customers, for example, but a "One-Time Customer" card could be used to track information about all your casual customers as a group. To add a new card, click the arrow button to the right of the Card field, then click the New button in the Select from List window.
