The ability for me personally as an individual user is that I can use it in multiple different ways without having too many buttons or options at my disposal (as there are lots).
It has helped improve our efficiency by allowing us all access from one system which makes things easier when we're out with clients/customers etc. There really isn't anything i dislike about this software but if you want something simple then perhaps try another option? We have been able to track leads more effectively than before using Sppro!
