Expenses & bills
Credit card charges, credits and payments
Keep a company credit card's balance right in your books.
Record card purchases as expenses paid from the credit card account; the card's balance (what you owe) goes up.
When a merchant refunds you on the card, record a credit card credit.
When you pay the card bill, record a credit card payment (Pay down credit card) from your bank account. The bank goes down and so does the card balance — it isn't an expense.
Reconcile the card account against each statement just like a bank account — see Reconciling an account.
