The Best Designers Have The Best Spreadsheets

I was just talking to a new client explaining that as soon as I’ve done some initial layout drawings I’ll be able to start entering data in a spreadsheet I’ve developed (with a banking expert and accountant) so that we can begin to produce financial models, which I’ll use to advise how best to maximise the returns he can get from his recently purchased space.

He seemed surprised that a designer could do maths or would use spreadsheets.

Strange that because, other than guesswork, I don’t know how else it can be done.
