Hi there, @erkorbgwg. I have some information and instructions to help you manage electronic signatures in QuickBooks Online, Allow me to help you.

As of the moment, e-signature is unavailable in QuickBooks Online. This feature's accessible in both the mobile app and the desktop edition of QuickBooks. For now, you can manually affix your signature or integrate a supported third-party app that's capable of doing this.

There are two ways to look for a third-party app. The first one is by going to the apps.intuit.website or by going to the Apps tab that can be found in your left navigational bar.

To begin with, here are the steps:

1. Go to the Apps menu at the left pane.
2. Select the Find Apps tab, and then type a keyword in the search bar like "E-signature."
3. Click the magnifying glass to search, and then choose the app that suits your need.

For visually reference, you can refer on the screenshot below.
