For a prospective client we have to offer a solution to provide following system:

• CMS
• Order Management
• Shopping Cart
• CRM
• Helpdesk
• Accounting & Finance
• Custom Functions

In order to save time and to avoid reinvent the wheel our idea is to integrate different off-the-shelf solutions. Their first requirement is that the system has to be hosted in their country which I think will exclude application like Aplicor, Netsuite & Salesforce.

Basically the nucleaus would be the CMS which would integrate all the other apps.

PHP or .Net based solutions would be our preferences as have inhouse expertise.

So far following are few combinations I have come up with:

• Joomla (CMS) + Virtuemart (Cart+Ordering) + Sugar CRM + Open ERP (finance) + OTRS

• Magento (CMS+Cart+Ordering) + Sugar CRM + Open ERP (finance) + Helpdesk Ultimate

• Drupal (CMS) + Ubercart (Cart+Ordering) + Sugar CRM + Open ERP (finance) + Support Ticketing System

• Sharepoint (CMS) + OptimusBt (Cart+Ordering) + Dynamics CRM + Great Plains + SharepointHQ

• Dotnetnuke (CMS) + DNNSpot (Cart+Ordering) + Sigma Pro (CRM+Helpdesk) + Open ERP

For Helpdesk I liked Zendesk but the server location was the stopping factor, similar for finance and CRM I liked Aplicor.

I would not like to go into detailed requirements as it would make things very complex.

Could you please suggest me which options are worth enough to start looking into? What other options we have?
