Here's how:
- Go to the Settings icon and select Custom Form Styles.
- Look for the template, then choose Edit.
- Go to the Design tab and select Make logo edits.
- Change the Placement as you desire.
- Click Done.

Moving forward, the new logo placement should appear on your estimates when sending it to your customers.
