A data-driven redesign that turned a broken checkout into a converting multi-brand supplement store

Subject

VOLMI is a Slovak e-commerce store selling supplements across several in-house brands — Biomie, Eifela, BACK2LIFE, Magnesium-Diasporal, Inflomega and Imurin — under one storefront. The store already existed, but its checkout was broken: shoppers browsed and added products to cart, then almost nobody completed an order. We redesigned the store end to end — UI/UX, frontend, backend and product analytics — and rebuilt the checkout around what the data showed was actually failing.

What have we done

Task

Before the redesign, VOLMI's checkout converted at effectively zero — the team could see visits and cart adds, but completed orders were flat at zero a week. The store carries six different supplement brands under one roof, so any fix had to work the same way regardless of which brand a customer arrived through, and it had to be grounded in what shoppers were actually doing, not guesswork.

Solution

We started with product analytics — instrumenting the funnel to see exactly where people left: which step, which device, which brand's product pages. That data pointed to the checkout itself as the main failure point, so we rebuilt it, then cleaned up the product and cart pages feeding into it. The rest of the store was redesigned around the same system: consistent brand tiles, product cards, and a shared UI kit, so all six brands feel native to the store instead of bolted on. The checkout went from zero completed orders a week to 3–4 carts a week at an average order value above €60, alongside a 25% lift in traffic and a matching rise in conversion rate.

The six brands sit side by side on a shared "Our Brands" section on the homepage, each with its own tile and positioning line, then link through to category pages built around use cases — sport and fatigue, digestion, energy — so a shopper can find what fits their situation instead of hunting for a specific product name.

The cart carries a coupon field and a running total before checkout, and every product page backs up its claims with specifics — dosage, certifications like "No.1 magnesium brand in Switzerland," and the lifestyle context the product is meant for — rather than generic supplement copy.
