Why choose us

The gap between your ads and your store is where you lose the most money.

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.

Localization is not translation.

Claims are rewritten for local regulation including EFSA rules, currency and pricing conventions are localised, and every language is handled by a native speaker rather than a translation tool.

(07) FAQ

Frequently asked questions and answers.

Common questions about Shopify Plus builds, migrations, CRO, UGC ads and ecommerce localisation.

Contact us

What does Conversion Design do?

We 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.

How much does a Shopify Plus build cost?

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.

How long does a Shopify Plus build take?

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.

Do you handle Shopify migrations from WooCommerce or Magento?

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.

What is performance creative, and how is it different from a creative agency?

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.

Do you work with brands outside Slovenia?

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.
