Easy integration with other applications like Salesforce or Project Management tools for example Asana/Zapier is very helpful I have never had problems so far which makes me really happy if it was that easy all time! Nothing as of now but overall great tool. It has taken some getting used too (especially since we are new in our team). But once your familiarized its not difficult anymore especially when using Zapiers integrations. Try out this product first before jumping into buying anything else because their products can be expensive compared to others. We use them mostly within my engineering organization where i work at an insurance company solving different problems related to business analytics.
