The ease of use, customization options as well has customer support for any questions or issues that we may have during our implementation process! I like how easy it was when setting up new patients in my practice with their information being automatically imported from Xero into EMRDatacenter so there were no errors/issues while doing this at all!! Also love having integrated appointment scheduling which makes life easier than ever before. There really isn't anything bad about using EmrDatcentre - everything works great & very user friendly. !
