We are running multiple joomla B2B websites that we would like to connect with a CRM called Info at hand ([login to view URL]) that is similar to sugarCRM but has many interesting features such as link to Virtuemart and a joomla customer portal. Check their website. We would like to team with a CRM expert that preferably knows IAH and can perform : - Customer portal setup and customization - CRM setup with notably customization of PDF documents - Asterisk parametering/setup with CRM the result will be customer portal that handles customer enquiries, knowledge base, project and quotes management, order tracking and link to an IP PBX. Please advise f you can help wth that with proof of experience and the information you require.
