Hi 9130348372422156!

Thanks for joining this thread.

I understand how important SKU is for your business. Though we're unable to add an SKU column in creating a sales transaction, we can search and select an item using it. Make sure to add the SKU to the product list:

1. Go to the Sales menu and select Products and Services.
2. Find the item and click Edit or click New to add a new one.
3. Enter the SKU in the SKU field, then tap Save and close.

Once done, create a sales receipt or invoice and enter the SKU in Products/Services field to select the right item. Also, you'll want to add the SKU in the description so it'll reflect when creating a sales transaction.

You'll want to check these links. These will show you how to set up product and service items in QuickBooks Online:

• Add product and service items to QuickBooks Online
• Use reports to see your sales and inventory status
