Thanks for the screenshot, jjules!

I've read the previous responses, and I'd like to directly answer your question by saying there isn't a report that will show the customer/project column.

What you can do is run the Transaction List by Vendor report and export it to Excel. Then, manually add a Customer/Project column and enter the name of the customer or project in each expense transactions. You can also remove other transactions that you don't need.

I see that my colleagues have already provided some references about customing reports, you can check them out.

If you'd like short and direct responses in the future, just tag me in. Have a good one!
