B2B events are among the most effective marketing tools for direct customer engagement – and they are data-driven. From invitations and registrations to follow-ups and measuring success, events are closely linked to the processing of customer data. Many companies use a CRM system (Customer Relationship Management). However, when it comes to event-specific processes, traditional CRM systems often reach their limits. This is where the following playbook comes in: it demonstrates how CRM and event management software can work together seamlessly – and how companies can use this integration to deliver events more efficiently and successfully.

CRM systems and event software serve complementary but distinct functions in a B2B marketing stack. CRM platforms manage ongoing customer relationships and pipeline data, whilst event software handles the specific workflows of invitation, registration, check-in, and post-event follow-up. Integrating the two systems — either via direct API connection or data export — allows event data to enrich CRM records and enables more targeted, personalised communication throughout the customer lifecycle.
CRM stands for Customer Relationship Management – the management of a company’s customer relationships. A CRM system serves as a central platform for managing all customer data and interactions – from the initial contact and sales process through to after-sales service.
In the context of event marketing, events are seen as valuable touchpoints in the customer journey. They provide a targeted opportunity for companies to engage with existing or potential customers – and a CRM system helps to strategically leverage this contact within the broader context of the customer relationship.
Overall, CRM primarily pursue's three main goals:
A CRM system should therefore support these three essential business activities through a central database and automated processes. At the same time, it provides an overview of all customer activities and helps ensure data quality.
Events are often held to attract new customers and retain customers. In addition, events can involve a variety of interactions between the target group and the event organisation. For these two reasons, a CRM system is of great importance in the context of event marketing. A CRM system can be seen as a central platform for supporting event marketing. The CRM system is used for the following:
An event management software – such as Oniva – is specifically designed to run events efficiently, professionally, and in a data-driven way. It offers extensive automation that supports both event organisers and participants. The aim is to simplify event planning, save time, and gain deeper insights into the behaviour and interests of the target audience.
Typical functions of event software that are not covered by a CRM system include:
Most CRM systems do not offer event-specific functionality. They are unable to support complex registration processes, personalised event communication, or the integration of hybrid event formats. This leads to two key problems:
A specialised solution like Oniva complements the CRM precisely with the event component – and automates core processes involved in event delivery.
In principle, data exchange can be achieved without a fully automated interface – for example, via a shared identifier such as a unique customer ID or by manually importing participant lists. However, as soon as real-time data is required or large volumes of data are involved, an interface between the CRM and event software is highly recommended.
The specific data exchanged depends on the use case. In practice, the following information is particularly relevant:
A system like Oniva not only enables the export of such data, but also prepares it in a way that is tailored to CRM systems – ensuring a seamless workflow.
Anyone running events while also using a CRM system must ensure that the data is accurate, complete, and tailored to the target audience. The following aspects are particularly important:
Oniva supports companies in connecting their CRM with event software. Flexible hidden fields allow for targeted synchronisation of data between CRM and event platform.
A CRM system provides the strategic foundation for successful customer relationships – but professional event marketing also requires specialised tools. Event management software like Oniva bridges this gap by digitalising, automating, and personalising the operational execution of events.
Those who view event marketing as a strategic element in B2B stand to gain twice over: better data, more efficient processes, and a more compelling event experience for their target audience. The integration of CRM and event software is therefore more than just a technical add-on – it’s a key success factor in modern marketing strategies.
Tip: With Oniva, you can use CRM data specifically for events and, conversely, feed event data back into the CRM in a structured way, for example via the HubSpot API. This ensures that every event makes a real contribution to customer retention and lead generation.
CRM systems are designed for customer relationships and sales processes, but do not cover many event-specific requirements. Features such as RSVP management, event websites, ticketing, check-in or hybrid event formats usually require specialised event software. Combining both systems enables more efficient processes and better data quality.
By linking CRM and event software, customer data, event histories and interactions can be managed centrally. Automatic synchronisation saves time, reduces errors and enables personalised communication as well as insightful reporting for marketing and sales.
Particularly relevant are attendance status, event histories, interests, feedback, check-in data and new leads generated from events. Structured data synchronisation improves post-event follow-up and helps companies develop their customer relationships in a more targeted manner.
