I like that you can have your data from multiple sources within one program so if there are discrepancies they will be brought up at once instead or having two programs checking each other's information makes for lots more work! It would also help me out alot personally as i am not always able keep my own info organized very well sometimes but this has helped others too :).
You need some time setting everything right after setup (or learning how) because its pretty easy in theory when doing things by hand vs code. But thats no fault just an improvement needed since most people understand concepts easily enough without any explanation really anyways :) Great product great service!! Really helps organize all important documents into 1 place which saves tons of paper/time overall.
