E-Invoicing Exchange Summit - VIENNA, Sep 22-24, 2025

This workshop is targeting private sector solution developers and public sector authorities. E-Invoices are integral part of a wider context in the entire business data flow. We discuss how governments could support this smooth flow between different business events, what governments could offer back to companies and how solution providers could come along. In the Real-Time Economy concept all business data belong to the entrepreneur and their sharing is only done with the entrepreneur's consent. Data is not a by-product of business, but an asset, because the value of data increases with better use.

Businesses should be able to focus on urgent business matters, on things that really make value for the company and increase productivity, instead of dealing with various time-consuming administrative activities. So how could reporting to the state also be beneficial for the entrepreneur?

Topics to be discussed in workshop:
+ Setting the general scene
- Data is an asset, how to improve the business data quality? Service providers views on improving data quality
- What is once only principle in data management?
- Public sector request for minimal amount of data

+ Mapping business events that happen before and after an E-Invoice
- E-Invoices nor digitalisation alone will make the change, let’s look at the general picture
- Where business data is generated (Digital Product Passport, eOrder, eContract, eWaybill, E-Invoice, ePayment) and how it could be reused for reporting (VAT, Annual reporting, packaging report, sustainability reporting etc), statistics and more
- What happens if there will be gaps in the data movement?
- Different views on architecture, data exchange, public sector collaboration with service providers

+ Launching proactive, personalised and value added services
- Which data-based services could govenrments provide to companies, examples of Business Viability Index and Tool for businesses to boost data-driven business decisions and KYC solution
- How to maximise the opportunies to create data-driven business environment by implementing data interoperability for business reporting, different AI-solutions and other digital services targeted to entrepreneurs?

In his presentation, Marcus Laube will present the latest figures, data, and facts from his cutting-edge market study, "The Global E-Invoicing and Tax Compliance Report: Watch the Tornado!" He will place the current developments in Europe within a global context and demonstrate how companies can optimally position themselves for electronic invoicing.

The Digitalization Dialogue under CIAT is working on a project around definitions and categorization of E-Invoicing, continuous transaction controls and other forms of digital reporting or e-audit, to create a Digitalization Classification Matrix. The purpose is to allow stakeholders in the field to use a common vocabulary and categorization of regulatory approaches. Based on this normalization, it will become easier to have a conversation about opportunities and challenges towards regulatory harmonization and interoperability.

Discuss the most pressing business-relevant topics with your peers and gain valuable information.

Partner Dematerialisation Platforms (Plateformes de Dématérialisation Partenaires - PDP) are service providers that have been certified by French government. They are entitled to issue and receive E-Invoices directly with other service providers who are certified as PDP, without going through the Public Invoicing Portal (PPF). 
As a partner of the tax authorities, PDP also handle directory updates, e-reporting and compliance checks.

All participants and speakers are invited to enjoy dinner and refreshments in a casual atmosphere. Use this perfect opportunity to intensify your business contacts and grow your network.

Embark on a journey of strategic foresight with thought leader Sampo Salmi as we navigate the impending wave of E-Invoicing mandates in today's dynamic business terrain. Instead of mere reaction, discover the unparalleled benefits of proactive compliance preparation. 
Join us for an insightful exploration into the transformative power of staying ahead, offering strategic insights, practical solutions, and a roadmap to elevate your business from mere compliance to a true competitive advantage.

An invoice starts with an order. An order starts with an agreement to enter into a business relationship. It's time to recognize that E-Invoicing isn't just about legal compliance. In this presentation, we’ll explore an alternative definition of compliance that encompasses the full nature of transactions. We’ll discuss the different approaches required for mandatory versus voluntary E-Invoicing scenarios and why E-Invoicing alone can't drive true business transformation. After all, it's just one part of the entire value chain. Join us to learn how E-Invoicing can be a catalyst for supply chain transformation and unlock substantial business benefits.
+ Understanding the importance of aligning E-Invoicing with trading partner and business require-ments in addition to legal compliance requirements, and what this means for companies
+ Key considerations for implementing E-Invoicing, whether mandatory or voluntary, and the (unspoken) relationship with EDI
+ Using E-Invoicing as a potential accelerator and bridging the gap with the broader value chain to drive business transformation by addressing real business challenges
+ Strategies for quick and efficient onboarding beyond high-volume trading partners

The introduction of domestic E-Invoicing and real-time reporting obligations is a critical issue for companies worldwide. Approaching this topic strategically, with the right stakeholders at the table and at the right time can support companies to minimize their costs, optimize their processes and ensure timely compliance. Failure to address these requirements promptly can lead to significant disruptions and will imply important changes in the way businesses deal with their customers, internal stakeholders and the tax authorities.
