As Lloyd mentioned Sage 100 and Simply Accounting are two very different Applications. 

We have not seen a Simply Accounting integration with Salesforce but if you plan to migrate to Sage 100 we can assist in migration. Also, we have an integration known as GUMU Salesforce - Sage 100 ERP integration which is a 5 star rated app on Salesforce AppExchange.  Please feel free to email on [email protected] if you need any more information or demo on the same. 

Sincerely,
Dinesh

Thanks Dinesh, I need help understanding whether Simply Accounting has an equivalent in Sage 100 or is it totally different?  If we need to migrate to a different plafform within the Sage family, that's fine, but I just need more information to understand..

You probably want to speak with a Sage Partner to learn how Sage 100 may fit with your needs.  Ask Sage to put you in touch with someone, or perhaps look in the 90Minds group.
