The most attractive feature of aggregate.IO, as far I understand it's price structure (it costs $50 per month).The support team always responds quickly with detailed answers or explanations when there are any doubts about my account use in particular situations.I haven't found anything so far which makes me dislike this software but maybe because we aren’t using all its functions at present time(we have just started working together), they could be improved further by adding more options/features like data backup function etc.,Also i would suggest taking advantage from their training sessions provided free-of cost through online platforms such as google hang out platform where one can get trained hands-on experience regarding certain tools available under aggregates portfolio.We solve our needs related to project management including reporting dashboard development and also provide customised reports within minutes after receiving required inputs via API integration.
