I like that it has all of my customer data in one place so i can access them easily when needed without having to go through multiple systems or apps etc.. It also makes managing our accounts easy as well! There are some things with catalyst which could be made better but nothing major at this time however these aren't too bad either since they have been working hard improving their product over recent years!! Very user friendly platform overall - very helpful especially if you're using more than 1 client/account from your business- just make sure there isn’t anything specific about another clients account conflicting otherwise its great :) we use Catalysts billing feature quite often (it integrates directly into QuickBooks) making invoices much easier & less confusing compared other similar platforms out now such As Sage X3 / Infor CloudSuite ect.
