How to adjust inventory quantity if inventories are not sold?

Welcome to the Community space, @huamei. I'm here to guide you on the steps on how to adjust the inventory quantity in QuickBooks.

You'll have to create first an inventory adjustment account to easily track the quantities that you need to adjust in QuickBooks. In case you need to adjust the quantities in the future you can use this account again for future tracking.

Here's how:

1. Click the Company and then Chart of Accounts.
2. Select the Account ▼ dropdown, then New.
3. From the Other Account Types ▼ dropdown, choose Cost of Goods Sold.
4. Name this account “Inventory Adjustments”, and then Save and Close.

Then, you can now adjust the number of your products.

1. Click Vendors and then Inventory Activities. Then, select Adjust Quantity/Value on Hand.
2. Select Inventory and then choose Adjust Quantity/Value on Hand
3. Choose the Adjustment Type ▼ dropdown, then select Quantity, Total Value, or Quantity and Total Value. Select the adjustment type option and then select your adjustment account.
4. Enter the Adjustment Date.
5. Select the Adjust Account ▼ dropdown, then select the adjustment account you set up.
6. Add Reference No. You can also assign a customer, job, or class.
7. Select Find & Select Items. Select the items you want to adjust. If you have a lot, search for any product in the Find field.
8. Select Add Selected items.
9. Add a new quantity for each item.
10. Hit Save and Close.

Once done, you can pull up the Inventory Stock Status by Item to check your product's quantity and make sure everything is set up correctly. For detailed steps, see this article: Adjust your inventory quantity or value in QuickBooks Desktop.

Also, you can contact your accountant so they can adjust the inventory quantity for you.
