Kellerfensteronline Integrates Window Configurator into Shopify

For many years, kellerfensteronline.de has successfully sold basement windows in large quantities. However, expanding our online business required more than just offering standardized products—it demanded a shopping experience that is both seamless and personalized. For a long time, we faced the challenge of providing this level of experience to our customers when purchasing basement windows. The solution came through the combination of Shopify and Fenzon, which has now enabled our vision of a tailored shopping experience in a cost-effective and professional manner, as Kevin Schöneck shared with us in an interview.

Shopify: Our Foundation for Success

We chose Shopify because it allows for the quick creation of an online shop with integrated payment gateways and customizable themes and templates, even without technical expertise.

“If you have some experience in the online space, you can easily realize and implement your ideas with Shopify.”

Fenzon: The Perfect Shop Upgrade

Shopify, by default, only supports static products or product variants via dropdown menus. Fenzon perfectly complements this with its SDK for complex building components like our windows. The integrated product configurator now allows our customers to customize their windows according to their exact preferences. Inputs are automatically checked for feasibility, visually represented, and seamlessly transferred to Shopify's shopping cart upon saving.

“Thanks to the easy integration of Fenzon with Shopify and the excellent support we received, we were able to launch our shop in record time.”

Positive Feedback and Increasing Sales

The response to our online shop exceeded our expectations. We were surprised at how quickly the first orders came in. Our customers appreciate the intuitive usability of our shop, reflected in consistently growing sales figures. This feedback motivates us to continuously improve our service and remain responsive to our customers' needs, with the clear goal of becoming the market leader for basement windows in Germany and Austria.
