Your credit card payment is Not the point in time that you paid for anything except Debt Payoff. Every date you used the card is when you bought something, and you paid them by giving the card to them. That reflects a Micro-loan you just took from VISA or AMEX, and now you are more in Debt to VISA or AMEX; the office supplies just got paid.
Then, you see that each "credit card charge expense" entry is increasing the running debt balance of the Credit Card Type of account in your business bookkeeping.
You get an Account Statement; that is not a Bill. It is your Statement of Activities, showing the amount you owe, showing any previous payments were received, and showing any returns or credits, fees, etc. That statement is not a Bill to pay; you did not buy anything from VISA or AMEX. They are your Lender. You didn't buy it all on that one date. There is no "sort, lump, enter" for this statement. It will be used to reconcile your account to their statement for verification, detection of errors and fraud, etc.
The Payment to the card provider simply shows the Credit Card Account as the expense. This is paying down Debt. This is not buying the office supplies, again.
The function of Transfer is: The two Balance Sheet Accounts (Checking and Credit Card) as paperless exchange, where funds from Banking (asset) paid down the card (liability) balance. That's why you do not assign this as Office Supplies or Dues or anything for P&L reporting. It is Debt Payment.
You Paid for Dues on the date they hit the credit card account with that charge; you don't pay AMEX or VISA dues. You pay some sort of Membership organization for your dues to them. Enter Expenses, individually, for the date and payee; from Credit Card, or from Checking, or from Petty Cash (cash on Hand) as the Source of the spending = how you were able to Buy it, already.
Paying the credit card balance is Cash Flow as expenditure, not as an Expense Account like office supplies or dues.
Hope that helps.
