The ease of use, it's quick to set up new users without any problems at all! Also easy for staff members who are not tech savvy or have never used software like this before as well.
Really liked that they were constantly looking out for how we could improve our service offering - always open minded about what was possible in terms of features etc. We've had no complaints so far but I'm sure there will be if/when things do go wrong (I hope!). It is good value too because you can get quite generous discounts when signing customers onto their 'gold' plan which has really helped reduce costs over time while still delivering great customer experience.
