Are you considering whether to usage Sage 100 ERP on-premises (traditional) or would you like more information about having a third party such as Sage or an independent host provide the general back-end maintenance and server hosting?
Here’s a great summary PDF which provides you with information on what your Sage 100 cloud hosting options are. Especially impressive is the detail which this document goes into when describing the Sage hosted option vs a third party hosted option.
Both of these methods of hosting Sage 100 ERP in the cloud get you to the same destination. Whether you choose to have Sage host or a third party seems to largely depend upon how many users you’ll have (Sage seems to win for under 5 user implementations) and what modules (third party hosts win when you need to access non-framework modules or perform other tasks such as email statements from paperless office).
