The use of web services is not restricted to client facing work. For example, we utilise our own version of XPOR to do many internal things.
Our QA library, with all of its Documents and Procedures each under the control of the responsible expert, is entirely provided using XPOR. Consequently Access to QA documentation is enabled for internal use and even external appraisal, in a secure and controlled fashion.
Our Sales and CRM system is built with XPOR, as is our Email Marketing system and Project Management sites. Sales team members and Projects staff can access and update critical client data, whether they are in or out of office. All built into our web system that also facilitates this website!
