Item´s Custom fields

I have another way on how you can customize your items and I'm here to walk you through the steps, aacosta14526.

You can use custom item fields to track specific information for the products and services you sell. Follow the steps below on how to do it.

1. Go to the Lists menu and select Item List.
2. Double-click any item on the list to open and edit it.
3. Select Custom Fields. Then select Define Fields. 
   
4. Name your custom field in the Label column. Names aren't case-sensitive.
5. In the Use column, select the checkbox to turn on the custom field.
6. Select OK to save the custom field.

Once done, your new custom item field now appears on the Custom Fields list for your products and services. You can now add custom item fields to custom transaction templates.

Reply to this thread if you have any other concerns about the item custom field. Remember, I'm only a few clicks away if you need further assistance. 

What you're describing you want is exactly how I've always seen QB work:

When you pick an item with custom fields both on the item and the sales form the fields will fill in.

You're not reviewing existing invoices/sales forms for the values, are you?  If so, they will be empty until you manually add the values there.
