Searching for unbilled payments

Hello. I have a construction company and paying my vendors can be complex. I worry sometimes that when paying vendors that have multiple line items that I forget to allocate the job to that item. I know that running the unbilled cost by job report will help me find any unbilled payment to a vendor, but how would I run a report to search for unbilled payments to a vendor that had no job tied to it?

I have quick books accountant 2013.

Thanks
