A congress is no ordinary event. It is a genuine logistical puzzle: spanning several days, sometimes across multiple venues, involving a multitude of activities and a large number of participants to coordinate.

To tackle this complexity, many organisations turn to specialised event management platforms. While these tools are effective, they often remain disconnected from the broader information system. This lack of synchronisation with the CRM, accounting, or core business tools almost invariably leads to data duplication, which complicates compliance with certain GDPR principles, such as data accuracy and the right to erasure.

Beyond these technical challenges, organising a congress remains a complex task in its own right. Here are five recurring challenges, along with practical ways to anticipate them.

Challenge 1: Defining a programme

The programme is the heart of any congress. It involves numerous speakers, often features parallel sessions, and can evolve right up to the final days. A cancellation or a room change must be reflected everywhere; otherwise, the information becomes unreliable. Centralising speakers, activities, and tasks within a single tool makes this process more reliable.

Challenge 2: Managing communication and invitations

Identifying the right contacts, sending out invitations, and following up with participants are all essential yet time-consuming tasks. Using a specialised platform quickly raises a question: should invitations be managed in the CRM or within this platform? Since contacts are generally stored in the CRM, data duplication becomes difficult to avoid. This results in fragmented databases and less reliable tracking.

Challenge 3: Managing registrations and payments

A congress often offers multiple tiers of participation: full or partial registration, members or non-members, accompanying guests, paid extras, and so on. Each profile implies specific pricing. This increases the risk of billing errors and adds to the burden of accounting checks. A customisable registration form, coupled with online payment and invoicing, simplifies this process. However, a word of caution: event platforms do not replace accounting software. Exporting and reconciling data often remains a tedious task.

Challenge 4: Mastering logistics on the event day

The event day concentrates all the pressure. Access control, crowd flow management, badge distribution: the slightest glitch can ruin the attendee experience. Using QR codes, tracking entries and exits in real time, and automatically generating personalised badges help streamline these critical moments.

Challenge 5: Keeping participants engaged before, during, and after

A congress takes months to prepare. Attendee interest can wane between registration and the event, and then drop off afterwards. Targeted communications ahead of time, automated reminders, and post-event satisfaction surveys sent out promptly afterwards help maintain engagement and capture valuable feedback.

Conclusion

Taken in isolation, each of these challenges remains manageable. Their accumulation, however, makes organisation considerably more complex. In many cases, the real issue does not lie in the event itself, but in the flow of data between the various tools used. This fragmentation leads to manual data re-entry, errors, and lost information.

The most effective solution is to adopt an integrated approach: a single platform bringing together CRM, invoicing, payments, and congress management within one unified database. Such centralisation reduces the administrative burden, allowing you to focus on what matters most: the quality of the congress and the attendee experience. This is precisely what Organon for Professional Organisations provides.
