Hi BCM-Electrical,
Thank you for reaching out and welcome to our community!
If you assign a location on any transactions associated with the Project, those transactions would show up in all location filtered reports.
I have also found 2 articles from our community on linking location with QuickBooks Time and Payroll for your reference:
1. Set up and use projects in QuickBooks Time
2. How do I import locations into payroll?
Thank you and please let us know if you require any additional assistance.
