Why a Custom Product Configurator Changes Everything

A custom configurator makes shopping fun, personal, and effortless.
Customers can see every change in real time, explore options on their own, and create a product that feels like it was made just for them.


For your business, that means:


  • More sales from engaged shoppers

  • Higher conversion through a smoother journey

  • Built-in upsells right inside the flow

  • Less support work for your team

A configurator doesn’t just sell products, it creates unique experiences your customers remember.

Why ready-to-use solutions don´t work

Slow and clunky

Most configurator apps take forever to load and feel outdated. Shoppers play around but often leave without buying.

Hard to maintain

Merchants spend hours uploading hundreds of images and managing endless variants just to keep products updated.

Limited flexibility

Complex product logic? Most apps can’t handle it. You end up bending your workflow to fit the tool, instead of the other way around.

Expensive fees

Many apps charge high monthly rates or even take a cut of every sale, eating into your profits month after month.

Don’t just take our word for it

  • Henning Albertsen

    Lucky-Kitty

    Our experience with stearis has been very positive overall as they took on a fairly complex task of migrating an entire shop from an outdated platform onto Shopify, often going the extra mile with respect to content optimization.

  • Dominique Graf

    HerzensTier

    Our collaboration with Stearis, particularly with Najam, has been exceptionally successful. Our online shop required optimization in UX/UI and conversion, and Stearis not only executed this with excellence but also surpassed our expectations. Najam is both a strategic thinker, who approaches challenges with analytical precision, and a highly effective implementer who brings ideas to life with speed and enthusiasm. He excels at fostering a meaningful connection between our brand and our customers. The impact of his Shopify expertise and meticulous execution is evident in the measurable results. We highly recommend the Shopify experts at Stearis for any business seeking top-tier e-commerce solutions.

  • Malte Sielski

    ZOLA Nutrition

    Stearis and the team provided us with very efficient and professional support in making custom UX/UI changes in the shop. The implementation progressed quickly, and Najam was very close to the project, which enabled a top-notch execution. The experience Stearis has gathered over the years in various areas is also very valuable.

    Our shop has been managed by stearis for quite some time, and we’ve always had great experiences! We’re also very satisfied with the relaunch. If you’re looking for a competent Shopify expert, you’ve come to the right place!

    LuxuryWood | Die Manufaktur

    We commissioned stearis for a shop project and are extremely satisfied. From theme selection to implementation and extensions, everything has been excellent. The custom product pages in particular are a real game changer for us!
