When i adjust inventory starting value so i have to choose which account in inventory adjustment account?

Hello, khalid.mgtcc@gma. 

Thank you for reaching out to the Community. QuickBooks offers a versatile Products and Services feature which, is great for managing your items on the go. However, to select which account to use in inventory adjustment, I suggest consulting your accountant to help you with this to make sure your books are accurate. 

Here's how: 

1. Click the + New button and select Inventory Qty Adjustment.
2. Enter the Adjustment Date and the Inventory adjustment account.
3. Select the Product and enter the new quantity.
4. Press Save and close. 

For more information, here's an article that talks more about the inventory overview and its setup.

It's my pleasure helping you and I'll be happy to assist you further, have a great day and stay safe!
