We evaluated the two most prevelant on-demand CRM systems - SugarCRM and Salesforce.com. This our first side-by-side review of the two packages. Which CRM Vendor Provides the Best Experience? The primay difference is that Salesforce.com is quickly becoming more of a "platform" than a mere CRM tool. AppExchange is growing every day and SFDC is constantly building upon their platform. SugarCRM is very different from all other CRM software providers since it's software is considered open source.
