There is sometimes a difference between a credit card and a debit card, the first one usually gives you a credit when the latter directly debits your Bank account. When a card directly debits your account simply create transactions from the Bank to the expense account setting the transaction type to 'Card payment' this way:
| Date |
Origin Account |
Target account |
Amount |
|
| 08/31/2003 |
My checking account |
My expense |
150.00 |
There is no need to create a card account for a debit card or a credit card used as a debit card because they work like cash or checks. You only need to create card accounts for real credit cards, when payment is debited monthly similarly to a loan.
