I like how quick my spreadsheets load compared with MS Office products! It also has many more options than Excel which makes calculating formulas very simple as well in comparison (especially when working within an accounting system). The interface could be easier at first but after getting used to its layout becomes much faster once again making calculations quicker overall time saved by not having any issues running large projects or tasks. Also being able use this product outside Microsoft office so that others who are less tech savvy will have access without needing special training unlike other programs they may need help installing etc., This allows me to do complex financial reports quickly rather then spending hours creating them myself saving money/time spent doing work outsourced due too lack off knowledge regarding software such excel formatting charts graphs formatting tables ect.. If there was no option i would say go out sourced if possible because some.
