HOW I WANT TO KEY IN CLOSING STOCK AT PROFIT AND LOSS

Hello there, @anggeriktaj.

I'd be glad to help you close your books in QuickBooks Online (QBO).

Before doing this process, you'll have to make sure that you've entered any outstanding invoices, payments, and expenses. Then, reconcile your accounts. Once done, you can finally close your books. I'd be glad to show you how to do that.

1. Log in to QBO as a master admin or company admin.
2. Navigate to the Settings or Gear icon and select Accounts and Settings.
3. Select the Advanced tab and click on the Edit or Pencil icon in the Accounting section.
4. Change the closing date and enter a password.
5. Verify the details, then select Save and Done. 

I've also added some screenshots below.

This is how it looks like if you create a transaction after closing your books:

I've also added this article if you want to edit the date when you'll close your books in the future: Edit your closed books.

You can always get back to this thread if you need further assistance or if you have other concerns with QuickBooks. I'd be happy to answer them for you. Take care.
