Hi
is there an option to make PAYMENT DUE: payment upon completion (Service industry)

Is there the ability to hide the price on a line item, as I often bundle services together which will be cheaper, i.e Line 1 by itself $300, Line 2 by itself $300.00, but when combined total price $450.00, I would prefer to hide the line price and enter it manually at the end, rather than the discount function.

Thank you for any advice
