Company:
Hörgeräte Seifert GmbH
Project Timeline:
Several-month development project
Services:
Software development, project management, and quality assurance
Summary:
Together with Hörgeräte Seifert GmbH, netTrek developed a customized software solution that enables lab customers to manage the entire ordering process for custom earmolds digitally. Through the online platform, customers can configure and order individualized earmolds using intelligent dependency logic that only allows technically feasible combinations. An integrated shop for in-stock products was also added, making the overall ordering process more efficient and transparent.
Challenge
The Challenge:
As part of its digital transformation, Hörgeräte Seifert GmbH, one of Germany’s leading hearing care companies with more than 90 locations across Bavaria, Baden-Württemberg, and Saxony, needed to modernize and standardize its internal and external ordering processes for earmolds.
The goal was to provide both lab customers and internal employees with a powerful, intuitive, and secure platform for conveniently submitting, managing, and analyzing orders.
One of the key challenges was determining the appropriate number of user roles and permission levels required to ensure both efficient workflows and secure access. Another important consideration was how frequently system data should be synchronized—daily or weekly—to achieve the right balance between data freshness, performance, and efficient use of resources.
Goals and Requirements:
The primary goal of the project was to create a clearly structured and user-friendly software solution that would:
- Digitize and accelerate ordering processes
- Significantly reduce manual work
- Create a transparent and reliable data foundation
- Generate long-term time and cost savings
In addition, customers needed to be able to configure and order custom earmolds online, while internal employees required automated tools for capturing, assigning, and processing incoming orders.
Solution
Our Approach:
netTrek worked closely with Hörgeräte Seifert GmbH throughout the project and followed an agile development approach. Regular coordination meetings, short feedback cycles, and testing phases made it possible to implement requirements precisely, incorporate new ideas flexibly, and resolve technical challenges efficiently.
Technical Architecture and Implementation:
A key component of the solution was a BigQuery integration connecting Firebase and Looker to provide scalable, high-performance data processing.
The initial dataset was imported manually to establish a clean and reliable starting point. A custom extension was then implemented to continuously monitor changes and automatically transfer updated data to BigQuery. The data was structured and processed there before being visualized clearly and efficiently in Looker Studio.
This architecture provides stability, transparency, and long-term scalability, creating an essential foundation for data-driven decision-making and continuous process improvement.
User Interface and System Structure:
The frontend was designed using Material Design principles and visually adapted to the corporate design of Hörgeräte Seifert GmbH.
The software consists of two main areas:
1. Customer Portal:
- Lab customers can individually configure and order custom earmolds online
- Intelligent dependency logic ensures that only technically feasible combinations can be selected, minimizing potential errors
- An additional shop provides access to in-stock products
- Customers can track order status, manage personal information, and view their order history
2. Internal Software:
- All orders are consolidated in one central system
- The system analyzes incoming orders, automatically calculates relevant parameters, and assigns them to the appropriate production or administrative departments
- Barcode scanner integration significantly accelerates production and shipping processes
- Interfaces to the accounting system enable automated invoice creation, shipping label generation, and direct printing
- An administrative dashboard supports order controlling, status management, and the administration of customers, employees, and shipping details
Project Management and Quality Assurance:
netTrek was responsible for both project management and quality assurance. The agile development process made it possible to test prototypes early, incorporate user feedback, and continuously refine the application.
Close collaboration with Hörgeräte Seifert GmbH employees ensured that the software accurately reflects real-world workflows and delivers meaningful benefits in day-to-day operations.
