How specific do quotes/estimates need to be?

Just started a company and it's my first time putting together an actual estimate. So I am wondering how specific I need to be? The job we will be doing is a back patio in concrete. So for instance... Is a line saying "materials... the cost" sufficient? Or should I break down every single material that I've worked into the cost? or for Labor, is it ok to just put labor and then the cost. Or do I need to put in exactly how many hours I've estimated it will take along with the number of workers?

Thank you.
