The ability to quickly deploy new features, without having any code or developer experience is very nice! I also like how it integrates with other products (such as Salesforce). It's not free - but this isn't necessary when you're working in large organizations where there are many benefits from using software such as these integrations between applications/systems etc.. Not much at all really; however they do have some great resources available online which can help if needed too :) We've been able use Smartter Integrator seamlessly within our organization since we started implementing systems across multiple departments including Finance & Supply Chain over 2 years ago now so no complaints here either :D.
