I'm here to lend a hand, highgrove.
I can show you the steps on how to post a negative opening balance on your credit card account:
Here's how to complete the process:
- Click the Gear icon at the top.
- Select Chart of Accounts.
- Pick the New button at the upper right hand in the Chart of Accounts page.
- Enter the Account Type, Detail Type, Name, and other necessary information.
- In the Balance section field, enter the negative opening balance amount as well as the date.
- Click Save and Close.
However, if you didn't enter an opening balance on your Chart of Accounts, you can see below article for guidance on how to handle it:
