I recognize how helpful it is to run a report with a time cost option in QuickBooks Online, @peter-maddison. 

I would like to reiterate what Talial mentioned that we can view that report if it's included in an invoice. Thus, I recommend sending our Product Development team feedback to help improve your experience. They can take a look and might consider this as part of future enhancements.

Here’s how:

1. Open your QBO account.
2. Hit the Gear icon at the top, then click Feedback.
3. Enter your comments or product suggestions.
4. Tap Next to submit.

You can track your feedback through the QBO Feature Requests website.

Rest assured that our product engineers are continuously working on improving your QuickBooks experience.

Once everything is good, see this guide to learn more on how to add and manage repeating transactions in QBO: Create recurring transactions in QuickBooks Online.

Please let us know if you have other concerns about this matter or QuickBooks in general. You can leave a comment below so we can respond as soon as we can. Keep safe!
