Thanks for reaching out to the Community, jarosplumbing.

I can certainly understand how an ability to integrate QuickBooks with your Google Calendar could be useful and have submitted a suggestion about it as of today.

You can also submit your own feature requests while signed in.

Here's how:
 

1. Use the Gear icon.
2. Go to Feedback.
3. Enter your comments or product suggestions.
4. Select Next.

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates page.

Please don't hesitate to send a reply if there's any questions. Have a wonderful Friday! 

Thank you ZachE!

I submitted feedback as you suggested.  Could you please let me know if there are any developments on this issue and any other possible avenues of getting the app developer to take action.  I appreciate your help!
