Best way of accounting for purchases made using a credit card?

****We present our Chase Visa credit card info to XYZ Distributors as payment. We receive the products and voucher the invoice as normal. At the end of the month, we want to produce a check to pay the Chase Visa credit card account.****

The Credit card should be an account in the chart of accounts

Either
enter a bill with the details, then use pay bills, select the CC and pay the bill and save
or
use an expense transaction, select the CC as the payment source, enter the details and save

You pay the bill by making a payment to the CC account, use that CC account as the expense (reason) for the payment

CC are not set up as vendors

Thank you for that lightning-fast reply!  Please verify that I understand this correctly.  I am processing a real order right now:

Ordered product from eBay and generated a PO as normal with eBay as the vendor and terms "Pre-paid with Credit Card".  I paid using Chase Visa card.  Then in Enter Bills & Vendor Credits, I received the products into inventory and processed the invoice as normal (eBay as the vendor still).  Then I used Pay Bills to pay eBay's invoice.  But instead of printing a check as I normally would, I changed Method to "Credit Card" and selected  Account: "Chase Visa" (it was already in Chart of Accounts as "Credit Card").  

How do I write the check for Chase Visa?  I can't use either Pay Bills or Write Checks, because Chase Visa is not a vendor and thus can't be selected from the list.  What is the trick?

Thanks again!

In paybills, using the CC was just you borrowing the money to pay the bill.

Just enter a check payable to the CC, and use the CC account as the expense (reason) for the payment.  This is a separate activity
