The best thing about store harmony is that it has all of my business needs covered! I love how easy everything was for me when i first started using this software (I am still learning but so far nothing). There are no downsides at least from what ive seen yet!! But if there were any they would be minor things like better support or more training material etc.. It's great because its made by people who know their stuff which helps alot with ease knowing exactly where we stand as an organization overall haha not just one person lol.
