Yes, you can close the books and edit them if you need to, angie-accountsol.

Closing your books prevents anyone from updating your accounting data before the closing date. Ensure to review your accounts. 

Here are the steps to close your books:

2. Choose the Advanced tab.
3. Click on the Edit pencil icon.
4. Select Close the books checkbox.
5. Enter a closing date. Give yourself a comfortable deadline. You shouldn't need to edit any transactions before this date. Your new bookkeeping work will start after this point.
6. 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.
7. Select Save and then Done.
