I lump everything together for the most part. When you line item, client feels they can on their own they can start removing things. They question specific charges. No, it's one price and that's it. I can't give you a break down because we price the entire job together as a whole.
There are some exceptions, like when a location is far I might detail out a trip charge so they know what's a stake if they have return visits.
For my large repeat clients, I line item everything as requested but they know if quantities change or things are dropped, that will change cost as a whole.
