I'll share details about adding signatures on your checks when printing them inside QuickBooks Online (QBO), @treasurer-zionst.
Currently, the option you're trying to access is unavailable inside QBO. As a workaround, you can order Checks from Intuit, which you can personalize and add signatures through this page, or utilize a third-party app that offers this feature. If you wish to continue with the find the app, I'll outline the steps below:
- On the left pane, select Apps tab.
- Select Find Apps.
- In the Search bar, enter a Signature as your keyword.
- Once you found the app, select the app and then click on Get App Now.
