Integrated Platform for Hallo

Providing a seamless experience for customers and employees—that was Hallo’s goal in optimizing its digital services. Hallo, a leading telecom retailer, partnered with Infodation to develop an integration platform that seamlessly connects Salesforce, Entra-ID, and the web channel. Thanks to Single Sign-On (SSO) with Entra-ID and a direct connection to Salesforce, commercial processes now run more efficiently, allowing customers to navigate effortlessly and employees to focus on what truly matters.

The challenge: Isolated systems and inefficient synchronization

Hallo initially operated a standalone website with its own data management. Results were manually synchronized with Salesforce for order processing, while the customer database was periodically synced back from Salesforce to the website. This process was not only time-consuming and error-prone. It also hindered the platform’s flexibility and growth.

Hallo’s request

Hallo wanted an integrated solution where Salesforce would serve as the primary System of Record. This solution needed to eliminate existing inefficiencies while remaining flexible and scalable to support future growth and development.

A future-proof website that remains easily expandable and performs optimally—without being dependent on a single provider.

Our Approach: Microservices and azure cloud

The first step in Hallo’s strategy was to renew the website. We believe in technological independence, so we opted for an architecture that prevents Hallo from being tied to specific vendors. Since Hallo already had experience with and licenses for Azure Cloud, it was logical to implement the solution within this platform.

We developed a microservices-based integration platform using Azure Functions. This approach offered multiple advantages: the scalability of Azure Functions makes the platform suitable for fluctuating capacity needs, and its modular structure ensures that future expansions can be implemented seamlessly. Additionally, this architecture enables Hallo to easily conduct A/B testing and continuously optimize its web environment.

Project progress

Our initial contact with Hallo took place in January 2023. Thanks to a strong connection with Hallo’s technical lead, we quickly identified the core challenges. However, defining the right strategy took more time, as other vendors offered standard solutions that did not adequately meet Hallo’s specific needs. Despite this pressure, management remained committed to its vision, resulting in a renewed web channel that perfectly aligns with the dynamic telecom reseller industry.

Throughout the project, we worked in biweekly sprints on the platform’s core elements. We also delivered interim solutions regularly to prevent other parties from being blocked. This approach allowed us to deliver significant value to the client within a short timeframe. Hallo consciously prioritized functionality over rigid processes, enabling a flexible and innovative collaboration. This "skunkworks" mindset remained intact, even with multiple parties involved.

"Infodation feels close, thinks strategically, and delivers robust solutions. That’s a rare combination."
Result: efficiency, ease of use, and growth

With the implementation of the new integration platform, Hallo has taken its digital transformation to the next level. Customers benefit from a seamless and secure experience thanks to SSO integration, while synchronization between the website and Salesforce is now fully automated. Employees who previously performed manual synchronizations can now focus on more valuable tasks within the organization. Additionally, website authorizations are now always aligned with the commercial processes in Salesforce, ensuring a consistent and efficient workflow.

Hallo has laid a solid foundation for future innovations. Integrations with self-service systems are just one of the next steps in its growth strategy. Infodation remains a committed and reliable partner, ensuring that Hallo always retains the freedom to make independent choices. This open and honest collaboration is the key to successful digital transformations like this one.
