The best Shopify Plus agency & performance creative studio.

Conversion Design is a Shopify Plus agency and performance creative studio based in Ljubljana, Slovenia. We build, migrate and optimise Shopify Plus stores, run conversion rate optimisation (CRO) programmes, and produce performance ad creative including creative strategy, static creatives, UGC ads, AI infomercial ads and high performing landing pages. We localise across 30 markets and have worked with more than 200 DTC brands, rated 4.9 out of 5 on Clutch. Conversion Design is a certified Shopify Partner. We also build custom web apps and our own products, including Adward, which we built to solve our own needs, so we ship software rather than just advising on it.

A Shopify Plus agency specialises in Shopify's enterprise platform, Shopify Plus (from $2,300/month), which unlocks checkout extensibility, Shopify Functions, B2B wholesale and higher API limits. You typically need one once you pass roughly $500K–$1M in annual revenue, when custom development and conversion optimisation start moving real revenue. We build and optimise Shopify Plus stores for 200+ DTC brands, targeting 2.0–3.5%+ conversion rates versus the 1.4% industry average.

Shopify Plus starts at about $2,300/month for the platform itself. For the build, our conversion-designed Shopify and Shopify Plus projects start at €5,600, with mid-range Shopify Plus builds typically €8,900–€30,000 and enterprise or headless builds higher depending on scope. Hourly Shopify Plus development is €75/hour, and every build ships mobile-first UX, sub-1.2-second load times and 96/100 PageSpeed scores.

Standard Shopify suits most brands under ~$500K/year. Shopify Plus (from $2,300/month) adds checkout extensibility, Shopify Functions, B2B wholesale, unlimited staff accounts and higher API limits, and it is worth upgrading once those capabilities move real revenue, typically at $500K–$1M+/year, high order volume, B2B, or complex localisation. We build on both and recommend the platform that fits your stage.

We migrate to Shopify and Shopify Plus from WooCommerce, Magento (Adobe Commerce), BigCommerce and custom platforms, moving products, customers, orders and content while preserving SEO and URLs with structured 301 redirects and post-migration QA. We re-platform migrations as conversion-designed rebuilds, not like-for-like copies, so the new store also lifts conversion rate.

Yes. Alongside Shopify, we build content-led WordPress websites and WooCommerce stores when that platform is the better fit. As a WordPress and WooCommerce agency we handle design, custom theme and plugin development, WooCommerce store setup, and performance and conversion optimisation.

We increase conversion rate by fixing the specific leaks a store audit surfaces: benefit-first product pages, social proof above the fold, a friction-free mobile checkout, faster load times (96/100 PageSpeed, sub-1.2-second), then A/B testing every change against revenue. Across 200+ DTC brands this conversion design process typically lifts stores from the 1.4% Shopify average to 2.0–3.5%+ within 60–90 days.

The average Shopify store converts at about 1.4%. A healthy DTC store sits at 2.0–3.0%, and well-optimised, conversion-designed stores reach 3.0–5.0%+. Rates vary by industry, price point and traffic quality, so the most useful benchmark is your own trend over time rather than a single number. Our clients average 2.0–3.5%+ after CRO.

Ecommerce localisation adapts a store's language, currency, payment methods, shipping and messaging to convert in each target market rather than serving one generic version. We localise across 30 markets spanning the EU, UK, US and beyond, using Shopify Markets and Shopify Plus's multi-store capabilities.

A conversion-designed build typically takes 3–6 weeks for a standard project and 4–10+ weeks for larger Shopify Plus builds with integrations, migrations or headless architecture. Timelines depend on scope, content readiness and the number of custom features.

We work with DTC and ecommerce brands across supplements, apparel, beauty, fitness, food, pets and electronics, among others. Our cross-brand pattern library from 200+ brands is applied per vertical, because what converts in supplements differs from apparel or beauty.

Yes. The large majority of our clients are outside Slovenia. We're based in Ljubljana but work with DTC and ecommerce brands across 30 markets in the EU, UK, US and beyond, delivering remotely in English.

Performance creative is ad creative built and measured against conversion outcomes like ROAS, CPA and CTR rather than aesthetics or brand awareness. Where a traditional creative agency delivers a campaign, our Conversion Creatives produce continuously tested Static Ads, UGC, B-Roll and landing pages for Meta and TikTok, averaging 6.8x ROAS across 200+ brands and 10,000+ creatives.

UGC (user-generated content) is authentic-looking video or photo content made by everyday creators that a brand buys with full usage rights and runs as paid ads, rather than posts on the creator's own account. It works because it feels native on TikTok, Instagram and Meta and often outperforms polished studio ads for DTC products. It drives sales when it is scripted around a tested hook and paired with a matching landing page, which is how we produce it inside our Conversion Creatives retainer (6.8x average ROAS across 200+ brands).

Yes. UGC is part of our Conversion Creatives retainer: each UGC video pack delivers 5 scripted, conversion-tested angles produced with vetted professional creators, in 9:16, 1:1 and 16:9 for TikTok, Meta and YouTube. We match creators to your product and audience, and every video builds on hook frameworks proven across 10,000+ creatives.

Yes. We produce AI video ads, including AI UGC and AI infomercial-style ads, alongside filmed UGC and B-Roll inside our Conversion Creatives retainer. We use AI to generate and iterate on hooks, avatars and B-Roll quickly, then keep every ad conversion-tested for Meta and TikTok. AI video is one lever in the mix, used when it beats filmed creative on cost, speed or performance, not novelty for its own sake.

Yes. Every creative is produced in the vertical 9:16 format for Instagram and Facebook Stories, Reels and TikTok, plus 1:1 and 16:9 where a placement needs them. Story and Reels ads are built mobile-first with a strong first-second hook, native pacing and captions, because that is where most DTC ad spend and attention now sits.

It depends on the plan: Core (€3,200/month, 32 credits), Growth+ (€4,400/month, 50 credits) and Elite (€7,200/month, 90 credits). Credits are spent across asset types (1 per static ad concept, 5 per UGC pack, 6 per B-Roll, 10 per landing-page pack), typically meaning 20–40+ new creative variations per month.
