Hi Renee,

I would like to add some more information about closing your books. 

In QuickBooks Online (QBO), you cannot directly close a month like you do while closing the year. However, you can achieve a similar outcome by setting a closing date and password. This method restricts any alterations to transactions dated on or before the closing date without the password.

To do this, here's how:

1. Go to the Gear icon at the top.
2. Select Accounts and Settings.
3. In the left menu, choose Advanced.
4. Go to the Accounting section and click the pencil icon.
5. Turn on the Close the books switch.
6. Enter a closing date.
7. Enter a closing date password.
8. Select the Allow changes after viewing a warning and entering a password option from the dropdown menu if you want to require a password before editing your closed books.
9. Click Save and then Done.

By following these steps, you can close a month in QBO and prevent any modifications to reconciled transactions.

For future reference, here's a great resource to help you close out your current year and prepare for the new year in QuickBooks with your accountant: Year-end guide for QuickBooks Online.

Feel free to post here anytime you have concerns about closing your books in QBO. I will be happy to assist you. Have a good one.
