Shopify development services

We build Shopify stores and the integrations, apps and B2B tools around them, as a small team in Oslo you work with directly. Projects start from $10,000, and we don’t take small theme adjustments.

Stores and tools we’ve built.

Shopify build

Kastel runs Norway, Sweden and the EU from one backend.

A headless Shopify storefront with shared content, product-specific collection pages and a store locator, and the measurement and testing tools to keep improving it after launch.Read the case study
“Skai Digital has been extremely skilled, service-oriented, and professionally competent in their process with us... I am extremely satisfied with the collaboration and would recommend anyone who needs similar services to speak with Skai before ordering services elsewhere.”

What we build

Most projects are one of these eight. Each has its own page if you want the detail.

New stores and rebuilds

A store built around how you sell, on a Shopify theme or custom code. We recommend whichever your catalog, content and team can actually run, and we write down why.

Migrations to Shopify

Products, customers, orders, URLs and integrations moved while your current store keeps selling. Fjordfiesta moved from Craft Commerce and kept its design. See Shopify migration services.

Shopify Plus

Several stores, advanced B2B and custom checkout logic, for the brands that need them. Not every store does, and we’ll say so. See Shopify Plus development.

Headless storefronts

Custom storefronts on Shopify with Sanity for content, when your content, brands or products justify the extra complexity. See our headless Shopify agency page.

ERP and warehouse integrations

Stock, orders, prices and customers moving between Shopify and your other systems. We’ve built integrations with Visma, Ongoing, ColliCare, ShipHero and Cin7. See Shopify ERP integration.

Custom apps

Built when nothing in the App Store fits, and not before. Verandah’s B2B trade application app is one example. See Shopify app development.

B2B and wholesale

Wholesale ordering portals and quoting tools for sales teams, for buyers who order differently from your retail customers. See Shopify B2B development.

Speed and ongoing development

We measure the speed real customers experience and fix what slows them down, then keep improving the store with you. See Shopify speed optimization.

How a project runs

The same four steps whatever we’re building. You work directly with the people doing the work from the first call.

  1. A call about what’s getting in the way

    Book 30 minutes. Bring a problem, an idea or a brief. We’ll tell you whether we’re the right team, and if something smaller or an existing app would do the job, we’ll say that too.

  2. Scope and price

    We look at your store, your systems and what success should look like, then agree the work and the price with you before anything starts.

  3. Build and test

    We build and test it with you, away from your live store, so customers only see it once it works.

  4. Launch and look after it

    We launch in a window you agree to and watch it closely. Then we stay on as your development team if you want us to, or you hire your own developers or choose another partner.

What every project includes, and what costs more

We talk through what you need on a discovery call, then agree the scope and price with you before any work starts.

Book a call

Every project includes

  • A discovery call, then a documented scope and price
  • Direct work with the people building it
  • Testing before anything reaches your customers
  • The launch, and close monitoring after it
  • Code you own, so you can keep us or move on

What pushes it up

  • A full storefront rather than one defined piece of work
  • A new design
  • Integrations with your ERP, warehouse or shipping systems
  • Custom apps and checkout extensions
  • B2B pricing, wholesale ordering or a trade portal
  • Several stores, markets or languages

Prices are in US dollars. Your Shopify subscription, apps and ongoing development are separate. Compare the plans in our Shopify vs Shopify Plus guide, or run your own numbers in the fee calculator.

Frequently asked questions

How much do Shopify development services cost?
Projects start from $10,000, and Shopify Plus work from $30,000. Headless builds typically run $30,000–$100,000. We agree the scope and price with you before work starts. Your Shopify subscription and apps are separate.
Do you take small theme adjustments?
No. We don’t take small theme adjustments, such as a new section, a colour change or a template fix. Shopify’s partner directory lists partners who offer theme customization.
What’s the smallest project you take?
On Shopify, a defined project from $10,000, such as one migration, one integration or one custom app. Our smaller projects are internal dashboards and AI agents, not small Shopify jobs.
Are you a Shopify development company or an agency?
Both words describe the same thing here. Skai is a small Shopify development agency in Oslo and a Shopify Select Partner, with clients in Norway, Europe and Australia. We work in English and Norwegian, and you deal directly with the people building your store.
What counts as custom Shopify development?
Anything a theme setting or an existing app can’t do. For our clients that has meant a shoe configurator, prices that follow the metals market, B2B quoting and campaign previews. We build on Shopify’s native storefront when that fits and go headless when it doesn’t.
How long does a Shopify build take?
A full storefront build typically takes around 12 weeks, followed by 4 weeks of close monitoring. A smaller project has its own scope and timeline, which we agree with you before starting.
Do we need Shopify Plus?
Not every store does. Revenue alone doesn’t settle it: Plus is worth considering when its checkout, B2B or multi-store features solve a specific need. Compare them in our Shopify vs Shopify Plus guide.
Can you work with our existing team?
Yes. We can take on part of the work alongside your team or handle the full build. We settle who does what on the first call.
Who owns the code?
You own the store and code we build for you. You can keep working with us, hire your own developers or choose another partner. Software from other companies has its own terms.
What happens after launch?
We look after what we’ve built and keep improving it with you if you want us to. We agree the priorities, scope and commercial terms together, so you know what the ongoing work includes.
“You will never work with anyone that is as painless, as good, as creative and as knowledgeable as you guys … I have only praise to say”
