Dynamics CRM Online vs. Salesforce.com

I'm delivering Microsoft CRM Projects since 2007 and loving it;
During presales activities, I have been asked many times to compare between CRM Online and SalesForce, I used to provide it on a limited scope,
till I decided to prepare a comparison and publish it, I'm posting this hope it will help in this regard:

Salesforce.com:

The salesforce application is an easy-to-use tool with deep SFA capabilities. The product also boasts strong functionality in partner relationship management and sound support for customer service. Where the solution is weaker, however, is in support for marketing, field service, customer analytics, and eCommerce.

The application is built on top of a modern architecture, allowing for robust scalability, reliability and availability, and openness to connect to other applications via Web services. However, the product is only available in SaaS deployment, so organizations selecting salesforce must be committed to the SaaS deployment model. It lacks industry-specific vertical solutions, with the exception of Wealth Management in the financial services segment. Along these lines, the vendor relies on its partner ecosystem (AppExchange) to complement its shortcomings in the areas where the application is not robust. Salesforce is an application best suited for businesses that are looking for an easy-to-use, rapidly deployable sales management and customer service CRM application, and who are committed to the SaaS as deployment approach.

• Very large established customer base
• No on-premise CRM capability (on-demand only).
• No vertical functionality and few vertical add-ons available for customers.
• Limited integration capabilities with existing productivity software and line-of-business (LOB) applications.
• The pricing is about twice that of Microsoft Dynamics CRM's Online edition.
• According to Nucleus Research, "38% of Salesforce.com customers are planning to or would consider moving to another solution."

Microsoft Dynamics CRM:

Buyers have a full range of deployment options: on-premise, SaaS, on-premise hosted, or hybrid.  The solution’s code is the same regardless of deployment choice, so migration from one deployment type to another is relatively easy. There are no industry-specific solution sets although Microsoft is working with its extensive network of ISVs to develop industry solutions on the Microsoft Dynamics platform. Enterprise buyers will be attracted to Microsoft Dynamics CRM if they have made a commitment to a Microsoft infrastructure in order to lower their TCO in buying and managing business technologies. Buyers also like Microsoft Dynamics CRM’s usability, lower price, and its quick time-to-value compared with traditional CRM applications.

• Choice of Deployment Model. Microsoft Dynamics CRM offers a hosted, on-premise, or hybrid deployment models.  Not locking in their customers gives Microsoft a unique advantage here.
• Native Outlook Interface. Makes training easier.
• Choice of Client. Native Outlook, Web browser, mobile, or online/offline.
• Ease of Configuration and Customization. Microsoft Dynamics CRM has been designed to allow customers and solutions partners to easily customize data types, workflows, role-based views, and more, through solution capabilities and standard Web services.
• Vertical Solutions and ISV Support.  Microsoft Dynamics CRM is supported by a global network of resellers, integrators, and ISV partners worldwide.  These solutions partners have deep experience building the custom and vertical solutions demanded by many customers.
• Low TCO.  Customers and solutions partners can take advantage of existing IT investments and in-house expertise to help minimize the total cost of ownership because Microsoft Dynamics CRM is built on the scalable and secure .NET platform and utilizes standard Microsoft tools and technology such as Microsoft SQL Server and Visual Studio.
