It is possible to block previous months of records to avoid untimely changes.

Hi there, Sandra-Jaspe. Yes, you can limit access to past monthly records by activating the Close the Books feature in QuickBooks. This function allows you to set a Closing Date, after which no changes can be made to transactions in the specified period without first removing or changing the closing date.

Before proceeding, be sure to reconcile your accounts first to ensure everything is balanced and to avoid any discrepancies or issues later on.

Here's how to enable on Close the Books feature: 

1. Navigate on the Gear icon.
2. In the Your Company column, select Account and Settings.
   
3. Go to the Advanced tab.
4. Click the Pencil icon in the Accounting section.
5. Activate the Close the Books feature.
6. Set a date in the Closing date field.
7. Set a Password.
8. Click Save, then Done.
   

After this, you can View Retained Earnings account details in QuickBooks Online to show the total of your company's income and expenses from all previous years.
