I and many of my clients use spreadsheet all the time in business. Actually after word processing, the first popular task that computers were used for in business was spreadsheets. I find them better than calculators as I can see each step and can take notes. Add 20 numbers on a calculator and who knows if one is wrong, on a spreadsheet you can review each number you put in.
As readers here will know our software uses spreadsheets a lot particularly for reporting so unlike so many other point of sale software, our software can produce flexible and dynamic reporting. It's a big plus.
Well if you are into spreadsheets, I have just discovered a great site with some brilliant spreadsheets with functions like calendars, resumes, time planning, timesheets, general forms, etc. They are extremely professional, look good and free.
