Many Open Source Solutions (CMS, CRM, Accounting Software, Email etc) are web based and as such can be installed on your own local PC's and servers but as an alternative you can also look to have this software hosted by a 3rd party which can often reduce the administration required by the customer leaving a specialist company to ensure that essential backups are performed, information is secure and systems are available to authorised personnel when required. Outserve offers hosting for many open source solutions from websites using content management systems to ERP and CRM.
