I was wondering when you invioce your customers, do you itemize the material used, or just give them a total amount? Does it differ from service calls to just T&M jobs. I know if you bid something, the customer doesn't need to know what the break down is. Currently I just give a total material amount. I installed a can light in an existing ceiling. T&M job, Invoice showed Labor 3hrs @ XXper hour and XX for material= Total amount owed. Then I give a desription of work done. No one has complained yet, but was just wondering how others go about this and how your invioces are structured.
