I've never actually asked or gotten questions about my invoices. So, either everything is crystal clear, or you're right, they don't look at them. I suspect every client probably looks at the first couple to get to know me and establish trust, and then just skims them thereafter. But it's nice for both of us--we can each review and see exactly what I did and how long it took.

Thank you. Yeah, I try to do the same with my invoices. My experience is about the same as yours. My current clients don't complain and they pay on time. It works well enough, but it takes longer for me to create each invoice.

OTOH, a while back I had a client that told me to stop detailing everything on my invoices. They just wanted a total number of hours. I think maybe it had to do with the review process upstream. Fewer details gave the higher ups less to scrutinize and complain about, I guess. And none of the other contractors were providing such detail.
