The main difference between an E-procurement manager and a normal procurement manager is that the former's procurement process takes place on the internet. While this automates some parts of the process, a manager would still need to be a great communicator and leader to effectively manage the team entrusted to them.
Because this position requires a lot of work on the internet, having an educational background and experiential competency in IT or computer science, as seen in this template, would be very attractive to employers.
