Hello there, Donny. I appreciate your rationale for the issue.

I'll share insights about the invoice header and format in QuickBooks Online (QBO) and guide you in sending feedback or product recommendations to help improve the features and your experience using the platform.

You're correct that QBO shows the time as quantity on invoices. Then, the format will convert to time (HH:MM) once you send one to customers. 

I can see how the benefit of being able to show time (HH:MM) on the invoice header instead of quantity would aid you in managing your income transactions with QBO. However, the option to option to do so is currently unavailable. With this, I would encourage you to send suggestions or product recommendations. We'll take them as opportunities to improve the various features of our products. Here's how:

1. Go to the Gear icon.
2. Select Feedback.
3. Type in your recommendation in the Share your feedback field.
4. Click Next.
5. Follow the on-screen instructions to complete the process.

Additionally, you can run a payroll report, like Time Activities by Employee Detail to monitor your employees' time activities, including hourly rate and duration. To do this, go to the Employees section in the Reports menu's Standard tab.

On top of that, I'd also recommend visiting this page to keep you updated with the latest software improvements and enhancements with QBO: Customer Feedback for QuickBooks Online.

Please feel free to leave a comment below if you have other feature concerns or questions about managing transactions in QBO. I'm always ready to help. Take care, Donny.
