Welcome to the Community, PlatinumDJ.
We're unable to suggest third-party applications that you can use to attach a signature on an estimate or invoice while using a computer. Though, you can check some applications that are compatible with QuickBooks Online through our App menu. I'll guide you how.
- Go to the Apps menu.
- Select Finds Apps.
- Search an app on the Find apps to streamline your work field or click Browse Category to find a suitable app that works best for you.
- Once you have found an app, click it and then select Get App Now.
I also encourage you to check out our QuickBooks Online Blog from time to time. There, you'll be updated with all the features and enhancements that our developers are working on.
Additionally, you can always browse our Income and Expenses articles. This way, you'll find some tips and related references for your future tasks.
You can always get back in this comment section if you have other concerns about managing your sales transactions. Doing so helps us to further assist you.
