The customer service was excellent, they were very helpful at all times during our implementation process - nothing! I cannot find any faults with this product or its team members (all great guys). We used to have an internal system that did most things but not everything we needed it for so Xtel came in as one solution which has been fantastic thus far. They helped us create reports from data stored within other systems like SAP & BI tools such as Tableau etc.- This gave me confidence going into my new role where i need those typesof report/data sources /solution set up myself without relying solely upon them again!
