YOURDAY: The scalable online shop for proWIN
A flexible headless approach for complex sales structures
Making dietary supplements an engaging experience is the mission of YOURDAY, a brand within proWIN that received a comprehensive facelift in autumn 2025. For the market launch, the company needed a powerful, flexible, and user-centered e-commerce platform that would incorporate the involvement of proWIN’s sales partners.
With our holistic, customer-centric approach to developing innovative digital solutions, we were the ideal partner to set up a shop system within a short timeframe that reflects complex sales partner structures while meeting modern UX standards. In addition to hosting the shop, we continue to support proWIN with ongoing DevOps operations following the launch, thereby fulfilling the Ergosign mission of simplifying the digital everyday lives of people through user experiences across a wide range of disciplines.
An intuitive online shop for complex requirements
The starting point
For the relaunch of the YOURDAY brand, proWIN needed a modern online shop that would seamlessly integrate into its existing sales structure. One particular challenge: Orders can only be placed with the involvement of selected sales partners.
At the same time, the platform had to accommodate complex requirements such as different fulfillment processes, country-specific requirements, and a mandatory registration process. The goal was to create a flexible and scalable solution that would support both business growth and the brand’s long-term digital strategy.
From analysis to tailored technology
Our approach
Following a comprehensive market analysis, we worked closely with the client in an agile process to define and refine the requirements. Flexible, adaptable, and consistently focused on user needs, this requirements engineering process provided the foundation for the subsequent implementation.
For the online shop, we developed a tailored technology stack based on a headless approach using Shopify.
We combined Shopify’s powerful commerce backend with the Hydrogen frontend. This ensures flexibility and scalability while laying the foundation for future growth — from integrating external shipping partners and expanding the system to adding new apps.
Our individually tailored development approach enabled us to seamlessly integrate the shop into proWIN’s existing sales structure and extend it with functionalities that go far beyond traditional e-commerce standards. These include complex fulfillment processes for different sales partners, country-specific product sets with individual product numbers, and a mandatory registration process.
Optimal user guidance leads to rapid adoption
Our solution
The result is a scalable, user-centered platform that appeals to both sales partners and end customers and provides a strong foundation for the continued growth of YOURDAY.
The shop’s modern and clear visual language not only delivers an intuitive user experience, but additional features such as a product finder, recipe modules, and a glossary encourage users to explore and engage with the brand. The YOURDAY online shop is therefore more than just a sales channel.
The project results speak for themselves — both economically and in terms of quality:
Rapid adoption: Within the first two weeks after launch, a four-digit number of orders was placed — a clear indication of the positive response among customers and sales partners.
Strengthened brand identity: The modern visual design, developed collaboratively by our team and proWIN’s graphic design team, conveys the YOURDAY philosophy and strengthens brand recognition.
Optimized user guidance: The product finder makes it easier for users to navigate the product range and quickly find suitable solutions. Subscription features create additional customer loyalty while providing greater predictability for proWIN.
Future-proof technology: The headless Shopify architecture enables future extensions, such as a dedicated app or additional content features, while ensuring long-term scalability.
Close collaboration: The strong partnership between proWIN and Ergosign is reflected in the website’s clear, modern, and user-centered design.
