Thanks for dropping by the Community, @smartin2.

I appreciate you checking other posts to look for a solution. Allow me to chime in for a moment and share some information about the adding Service Date on QuickBooks Desktop (QBDT) reports.

Yes, @Anonymous is right. Adding Service Date on the Sales by Customer Detail report is currently unavailable in QBDT. I can see how this feature would be helpful for you and your organization, and I'm going to submit feedback directly to our Product Development Team for consideration in future updates.

I also encourage you to submit feedback as well. They're constantly looking for great ideas from users, like yourself, when deciding how to enhance QuickBooks.

Here's how:

1. At the top menu bar, go to Help and pick Send Feedback Online.
2. Enter your request/product suggestion, then click Next.
3. Choose Skip and send a message, then select Feedback as the Category.

That should answer your concern for today. Please let me know in the comment section if you have any follow-up questions or concerns. I'll be here to answer them. Take care and have a good one.
