I had a commercial real estate appraiser as a client once. She had a massive excel workbook for the calculations her and her employees used. Originally it was set up so they input everything by hand, used a calculator to figure everything out, input the answers back into excel then copy and paste everything manually into a report template.

I made it so after inputting less than ten variables it automatically calculated everything they needed, generated several charts and graphs, and a fully completed report at the press of a button. I turned it from a two or three day job into a 10 minute one.

Needless to say my client was fairly excited.
