Need report! Vendor bills that are missing customer name

It's my pleasure to assist you today, JGonzales21.

While there isn't a specific report in QuickBooks Desktop (QBDT) that shows vendors bills with missing customer name, you'll want to run the Job Cost Detail report as an alternative. The report shows all the vendor bills that are under a Customer:Job.

 I'll be glad to guide you on how.

1. Go to Reports from the left menu.
2. Type in Job Cost Detail in the search tab.
3. Then, click Run to run the report. 

Once you open the report, you'll see under the Source Name column the Customer:Job. Below are vendors that are linked to the Job. Please see the image below for reference.

RE: my customizing of existing designs is pulling the vendor name (Source Name) into the customer (Name) field which is not helping me to identify those entries that are missing the customer.

Unfortunately that is (I think) the only way to determine the detail lines missing a customer: If the detail line on the report has the Vendor name in the Name column, then there isn't a customer:job on that row of the bill.

I hope you found your answer already but I ran across your question and wanted to see if I could help. I think the report you could use is under Job Costing and is called Expenses Not Assigned to Jobs. Hope that helps!
