SKU a unique identifier.

You've come to the right place, @alhaseeb36.

You can enter a unique name or code in your SKU field to make it unique. This way, you can add multiple products with the same name. Let me show you how.

1. Sign in to your QuickBooks Online (QBO) account.
2. Go to the Sales menu.
3. Select Product and Services.
4. Click New to add a product or Edit to modify your current products.
5. Add a Name, SKU, or Category for what you're tracking.  
6. Then click Save and close.
