Hello there, @may17.

Thanks for reaching out to us here in the Community. I can help you add multiple jobs for the same customer in QuickBooks Desktop (QBDT).

You can set up or add multiple jobs for the same customer on the Customer Center. Here's how:

1. Go to Customers menu at the top.
2. Pick Customer Center on the drop-down (or press Ctrl + J on your keyboard for the shortcut).
3. Right-click on your customer's name, then select Add Job.
4. Enter the necessary information, then click OK once done.

You can follow the same steps for adding additional jobs. For your reference, you may check out these articles for more information:

• Track job costs in QuickBooks Desktop.
• Customize customer, job, and sales reports.

That should do it! Please let me know how it goes or if I can be of additional assistance by leaving a comment. I'm always here to help you out. Have a good one.
