Why choose us
A creative agency promises one thing. A dev agency delivers something else. Nobody owns the handoff. We run both as one loop, with one team.
One team
Shopify Plus Store
Built to convert
Design system01
A CRO audit first, then a custom theme built on it: benefit-first product pages, social proof above the fold, a friction-free checkout and mobile-first UX.
Fast, tested build02
Clean Liquid, optimised images and a minimal app stack so the store loads fast on a phone. ERP, CRM and app integrations plus multi-market payment, shipping and tax.
Test winners03
Zero-downtime cutover during low-traffic hours, 48-hour monitoring of checkout and integrations, and A/B testing infrastructure live from day one.
Real customer data04
Conversion rate measured before the build and again 60 to 90 days after launch. Real customer behaviour decides the next round of changes.

Trusted by 200+ DTC and ecommerce brands, across 30 European markets.
Having the store design and the ad creatives handled by the same team was the biggest advantage. Marketing performance improved significantly within 60 days of launch.
They produced static ads, UGC videos and B-Roll that consistently outperformed our previous creatives in click-through and conversion rate on Meta.
They identified the exact drop-off points in our checkout flow and redesigned those pages using CRO-tested patterns. Measurable increases in online sales conversions followed within weeks.

(07) FAQ
Common questions about Shopify Plus builds, migrations, CRO, UGC ads and ecommerce localisation.
Contact usWe are a Shopify Plus agency and ad creative studio based in Ljubljana, Slovenia. We build, migrate, and optimise Shopify Plus stores, and create the ads and landing pages that drive traffic to them.
Our web and creative teams work closely together, so the website and ads are built to work as one. We also run ongoing conversion rate optimisation and creative testing programmes and localise stores and creatives across 30 European markets.
More than 200 DTC brands trust us with their websites and creative.
At Conversion Design a theme-based Shopify Plus build starts at €5,600. Mid-range custom builds run €20,000 to €50,000. Shopify's own Plus licence is billed separately by Shopify. Cost is driven by three things: the number of unique templates, how much custom logic sits in the checkout, and how many markets launch at once. Scope and price are fixed before work starts, so the quote does not move mid-project.
A theme-based Shopify Plus build takes 6 to 8 weeks. Mid-range custom builds take 10 to 16 weeks. A migration from WooCommerce or Magento adds 2 to 3 weeks for data and redirect mapping. In practice the schedule is set by how quickly product data and content arrive rather than by development, which is why the first week goes on a content inventory.
Yes. Conversion Design migrates stores to Shopify Plus from WooCommerce, Magento, Odoo and custom platforms. A migration covers products and variants, customer records, order history, and the part most migrations get wrong: URL redirects. Every old URL is mapped to its new equivalent before launch so existing search rankings survive the move, and Search Console is monitored after go-live to catch anything that slipped.
Performance creative is ad creative made to be tested rather than admired: static ads, UGC video, B-roll, landing pages and the angles and hooks behind them, produced on a cadence and judged on results. A traditional creative agency sells a campaign and a brand system. Conversion Design produces the assets and runs the testing programme, but does not buy media. You or your media buyer runs the budget; we make what goes into it.
Yes, a lot of our clients are outside Slovenia. We are based in Ljubljana and work with DTC brands across 30 markets, including Germany, the UK, the Netherlands, the Nordics and the United States.
