While there's no built-in feature to automatically populate the blank item description field with previously used information on an invoice, there are workarounds I can share. I'll outline two approaches since this post doesn't have an initial product tag whether you're using QuickBooks Online or QuickBooks Desktop.
In your case, we can add the information directly to your item's profile. The description field will be filled automatically whenever you create an invoice and select the product.
Here are the steps to follow:
- Head to the Sales menu, then Products & Services.
- Locate the item and click Edit.
- Enter what you want to describe it in the Description area.
- Hit the Save and Close button.

If you're using QuickBooks Desktop, there isn't a built-in feature to automatically fill the blank description field with previous information. In the meantime, you can manually enter the details or copy them from an earlier invoice.
Additionally, consider including the definition in your item's profile. Here are the steps to get you going:
- Hover over the Lists menu, then Item List.
- Click the item and fill in the Description area with your desired details.
- Select OK.

After you include the description in the item's profile, you won't have to re-enter it each time you generate an invoice.
For future reference, if you have received payment from one of your customers, you can record it. Here are the articles you can use for guidance:
