The integration with our HR system made it super easy! We have been able use this app in conjunction with other applications we were already utilizing without additional costs or effort from their end (no new apps required).
I haven't found anything yet but if there's something not quite what they need - feel free ask us through support@subitupapp.com so maybe together can find solution :) Integration has helped take away some manual inputting/entry process which was very tedious before and now makes things much easier when needed as well allows me access via mobile devices too while out at meetings etc.
