AllData Manage Online user here.
It's different compared to the AllData Manage DVD version. I freaking love it. All cloud based and is continually updated with improvements on the fly. My wife (who has no experience what-so-ever in the industry) has started using it and finds it pretty intuitive. I now have her putting together estimates, invoicing customers, taking care of the CRM, ordering parts, etc. It is subscription based at $104 per month...but the productivity numbers are well worth the investment! Way cheaper than another employee.
Because it's cloud based, I could be on the road with an iPad or even my iPhone and could look up customer info, put estimates together, order parts, etc. Also get up to three user logins. My wife and I have our own so we can work on separate computers at the same time.
