To be a customer-friendly and customer-focused organization, and to comply with GDPR legislation, it's helpful to create your own customer portal. In addition to various functionalities, customers can view their own data there, clearly showing how it's used within the organization. They can enable or disable certain features with checkboxes. They can also edit their own customer data, which is also required by GDPR.
Mediaversa has extensive experience with customer portals. Check out our own customer portal, where you can view and download invoices and get an overview of your current subscriptions.
Customer portals are relatively easy to implement, and the most basic versions can be up and running within a few days. Inquire with your account manager about the possibilities and for examples.
