To be clear, it is the same Sage 100 (you know and love), running on a hosted server.  Not a "Cloud version".  (On-premise software running in a cloud environment is not the same thing as native-cloud software).

Any hosting environment works, but there are a few specialists.  Check out the Sage Partner Cloud program, which has the Sage offering (through your Partner) and a few affiliated hosts.

Yes, we understand it is not a true cloud product, just trying to alleviate some of our IT responsibilities hosting our own server.  DSD brought Cloud at Work to the table (sure they have a financial obligation to each other) so just doing some due diligence on other Sage users experiences.

DSD makes quality recommendations.  One Sage 100 hosting specialist we've worked with is GoToMyERP, which might be worth considering.

We have used Summit Hosting for years very successfully. They are a Sage Authorized Hosting Provider.  Contact Jake at 877-922-1049.
