Hello there, @tab.
Thank you for joining the thread. I'm here to help guide you record your transactions correctly in QuickBooks Desktop (QBDT).
To give you the right amount of information, may I know what are you referring to when you're asking about how to post the second payment?
If you're referring to applying/linking the credit card payment to the bill you've created. Then you can pay the bill following these steps:
- Go to the Vendor menu.
- Select Pay Bills.
- Select the bill created.
- At the bottom part of the page, select Credit Card under Method.
- Select a credit card account under Account.
- Click on Pay Selected Bills.
- Select Done.
For additional reference about accounts payable workflows in QBDT, you may check this article: Accounts Payable workflows in QuickBooks Desktop.
You may also check our help articles for you future reference: Help articles for QuickBooks Desktop.
Stay posted if you have any other questions about handling/recording transactions in QuickBooks, I'll be always here to help you. Wishing you the best!
