Abstract
Mobile ERP is not per se something new or even special. It is an issue growing to become more and more important and enabling mobility due to the technological revolution and more so due to the mobile users. Mobility is about how businesses can provide a better infrastructure through mobile applications and services. While ERP was an important step taken by many firms, provision of services through mobile technologies is now inevitable. Together with other trends that are changing the enterprise applications landscape, ERP systems have to support the mobile behavior of their users. The paper explores the mobile applications landscape and proposes an architecture model for the mobile services starting from the necessary functionalities for a portal of mobile services. Besides the general architecture of the portal, a set of minimal functionalities for implementation is proposed in order to ensure the promotion and use of services.
