Newby-Putting together price build up for quotes

I am trying to put together an Excel sheet that will allow me to do a price build up into a quote. E.G I have a base tractor and I want to put on a loader, a mower, a plough etc that fit that model only. I then want to present it in quote form with the price built up with my costs in one area and my sales price in another. Is this very complex? Any advice or help much appreciated. I am sure it is just a databas exercise, but if someone can give me some clues to get started with the formatting or free ready made formatting

Surely, format is the least and last of the issues? First you have to determine how you want to identify what is allowable and so on, which is data design.

That is for you to decide, when you have that, we can help you build it.
