The integration between all our systems has been very smooth even though we are using different platforms from other vendors like Salesforce which was not at all easy but now everything seems fine! We have had some issues integrating with Dynamics 365 however they were resolved promptly and professionally so I would recommend them as well if you're having any troubles or questions regarding this product - They really do care about their customers.
There isn't anything bad i can say about this software nor did i find something exceptional either. Its great for managing tasks within multiple departments such as HR department etc.
