Electronic invoicing rollout and the rise of AI tools define several industry conversations in 2026 and dominate the congress agenda. Congrès de l’Ordre des Experts-Comptables 2026 takes place from 16 to 18 September 2026 at Paris Expo Porte de Versailles and brings together firm leaders, software vendors and institutional stakeholders.
Dates and venue details
The congress runs over three days, from Wednesday 16 to Friday 18 September 2026. Opening hours start at 10:00 on Wednesday and extend until 20:00. Thursday sessions begin at 08:00 and run through 20:00, while Friday closes at 17:00. The location is Paris Expo Porte de Versailles, 1 Place de la Porte de Versailles 75015 Paris, accessible via metro line 12, Porte de Versailles station.
Key themes and formats for 2026
Organizers structure the program around two main themes. First, electronic invoicing with sessions on implementation, company obligations and the role of accounting firms in supporting clients toward dematerialization platforms. Second, artificial intelligence with a focus on automation tools, operational impact for practices and new finance leader tools.
The program combines plenaries, workshops and masterclasses. An exhibition area hosts editors and technology providers presenting connectors and management solutions.
Attendee and exhibitor profile
The audience comprises accountants, firm staff and ecosystem players such as software vendors, consultancies and institutional partners. Exhibitors present products for tax and accounting management, connectors to ERPs and treasury tools.
Practical tips to prepare B2B outreach
Set daily objectives and prioritize leads by fit. For e-invoicing solutions prepare short demos that highlight compliance pathways. For AI-based products focus on concrete use cases and efficiency metrics. Bring technical one-pagers that detail integration points and deployment timelines.
Book short meetings in advance and target morning slots on Thursday and afternoon sessions on Wednesday, when program activity is denser. At the exhibition, request connector demos to validate compatibility with target clients. Use a simple intake sheet to capture needs and rank follow-ups after the congress.
Visitor logistics
The venue sits in the 15th arrondissement with direct metro access and multiple bus lines. There are RER connections and shuttle options from major stations as provided by the venue. Registration and detailed schedules are available through the event platforms.
Closing note and official link
