Hello there, mkashlak.

Thank you for posting here in the Community. Allow me to step in and help provide additional information about the Product/Service description in QuickBooks Online.

You can change the sales and purchasing information through the Products and Services section to autofill descriptions.

Here's how:

1. On the left panel select Sales.
2. Go to the Product and Services tab.
3. Choose an inventory or service.
4. Click Edit.
5. Below Sales information, enter what you want to reflect on sales forms.
6. Below Purchasing information, enter what you want to reflect on purchase forms.

The data entered on the inventory information will now reflect when creating transactions.

I'm always available here if you have any questions about your products in the system. I'll be sure to get back to you.
