Hi,
I believe you have received our comments on this question via email communication, so just to repeat for others who may be interested:
There are no built in connectors or module available since it always requires lots of customization according to specific client's needs. Some of our partners were able to integrate Kentico CMS with known systems with no bigger issues, since Kentico
CMS is standard ASP.Net web project and our API is wide open.
We haven't heard of any specific integrations with SugarCRM; however many clients integrated KenticoCMS with Salesforce and MS Dynamic CRM. In the pending release of
Kentico CMS v6.0, there will also be a new Kentico CMS
Integration Bus that will make the integration of Kentico and other 3rd party applications much easier.
Integration providers will be able to connect to provide synchronization with external systems. You will be able to register your own connectors to synchronize the changes either synchronously or asynchronously anywhere you want.
So then the decision is rather on which CRM does your client prefer.
Regards,
Zdenek C.
