The challenge

Maison Cosmetics needed more than a stock Shopify theme. The German store required custom theme work for campaigns, a quiz that guided shoppers to the right products, a checkout funnel that protected conversion, and A/B testing so the team could compare variants with real data instead of guessing.

Theme limits

Default sections could not support VoluFine campaigns, sticky CTAs, or flexible merchandising blocks.

Discovery friction

Shoppers needed a quiz-style funnel that routed them to the right serum or routine with tracked outcomes.

Unmeasured changes

Without A/B testing, landing and checkout experiments were hard to validate before rolling out.

How we approached it

Theme customization. Extended the Shopify theme with custom Liquid sections, campaign-ready templates, mobile-first layouts, and editor controls so merchandisers could update promos without a full rebuild.
Quiz and checkout funnel. Built a quiz-led product recommendation flow that captures answers, fires analytics events, and redirects to targeted product URLs. Strengthened the path into checkout with sticky CTAs, urgency messaging, and cleaner handoff into cart and payment.
A/B testing and measure. Wired tracking and test variants for key funnel and landing experiences, then reviewed the first month of live data against the prior period to confirm what the theme and funnel work actually moved.
