Thanks for bringing this to our attention, CMG 2020,

You can add a logo to your invoices in QuickBooks Desktop. And, I'm glad to show you how to perform this in the system.

The following steps outlined below will guide you through:

1. Go to the Lists menu, then pick Template.
2. Double-click the template you’d like to edit. 
3. Select the Formatting tab, then select Manage Templates. 
4. Mark the Use logo box, then chose the image from your folder.
   
5. Click OK.

For best results, use a logo image that is square. The image will be reduced and sized to fit in a square space. You also need to use the .jpg format instead of formats that have transparent background (.gif, .png, .tif).

Doing those steps above will ensure you're able to attach a logo to your invoices.
