I'v tried many over the years and many demos and I still haven't found one that will do it all the way we want. After spending thousands over the years we still use Sage50 with recurring invoicing/customised templates for accounts, Ez Management for Scheduling/Quotes and Outlook/Word for all else. It depends a lot on whether you want a fully integrated system (accounts, engineers, scheduling, stock, SMS, CRM, iPhone, Android etc....). As with all software of this type it is only as good as the work you put into the setup of it. The big question is how much do you want to spend upfront hundreds or thousands and how much is the ongoing service costs (again hundreds or thousands).
PC/ Server Based:
Cash 4 Windows, Alarm Master , Tracker Pro, Winsims, Ez Management, Clik Software, Sage CRM, Alarm Manager, - favouirites/cost effective are EZ Management, Tracker Pro & Clik Software
There are also quite a number of cloud based options which may suit depending on your requirements, try:
Click Software, ServiceM8 (Service Mate), Service Max, Fieldaware, Synchroteam - favourite/cost effective ServiceM8
Whatever you choose the key is to research it fully and trial run it for min 3 months. If you find the holy grail be sure to share it with the rest of us.
