This paper introduces a new approach to modeling of e-Ordering and e-Invoicing solutions. Today, electronic means to conduct purchases and sales are essential activities for companies operations, and they need to decide how to implement e-Ordering and e-Invoicing, what software solutions to use, and how to integrate them successfully with their current software. The nature and application field of electronic services such as e-Ordering and e-Invoicing dictates increased interoperability between different platforms. EU-introduced Pan-European Public Procurement Online project, presents an effort for unifying the large variety of procurement solutions from various EU and non-EU countries, and uses CEN/BII profiles to introduce interoperability between them. This paper presents the summary of our analysis of the CEN/BII profiles, and introduces modifications and improvements to this model, to help the flexibility and ease of further modification of the model.
