We are solving problems of our customers in terms or data quality management through an API interface to their CRM system that is hosted outside India (SAP Hana). The main problem here was integration with other products like Sharepoint which we solved at last few days during this project's life cycle as well! Not much dislike about it but would love if there could be more options while searching product catalogs from within mobile app itself instead than going into external search page every time! Excellent customer service support team who were available online all throughout day long whenever needed!! Would recommend everyone interested can go ahead because they will provide you best solution without any hassle!! Integrating third party systems / applications such share point document library etcetera via api callouts/ webhook calls has been one major issue i have seen so far when working over bluecosoftware-integration services provider partner partners. This also provides better control.
