How do I connect my corporate credit card to my quickbooks account?

Hi steventp1, thanks for posting on the Community

If your bank isn't available to connect to under Open Banking in QuickBooks, you can instead add the account in your chart of accounts. 

When adding the account, set the Account Type and Detail Type to Credit Card. 

Once added, transactions can then be entered manually, or you can import a CSV file containing the transactions downloaded from your bank.
