Does Frntkey support Centra?

Yes, on a project basis. Frntkey's native, productized backends are Norce and Shopware. Centra can be connected through a custom adapter built for the specific project. The adapter maps Centra's API to Frntkey's internal data model. Klarna, Voyado, and the rest of the Frntkey integration set connect through Centra's checkout.

How long does a Centra-plus-Frntkey project take?

A Norce-based Frntkey project typically launches in 6 to 12 weeks. A Centra-based project adds 4 to 8 weeks for adapter development, depending on scope. The difference is that the Norce and Shopware adapters ship with the product, while the Centra adapter is built per project.

Centra or Norce with Frntkey — which one?

Both are Swedish, API-first, and work with Frntkey. Centra is stronger for D2C fashion with multi-market inventory. Norce is stronger for mixed B2B/D2C with deep Nordic ERP integration. Norce comes with the productized Frntkey delivery model (native adapters, defined timeline). Centra is a project-scope integration. The right choice depends on the operational model the merchant already runs, not on marketing.

Who maintains the Centra adapter after launch?

The adapter development is scoped and delivered as part of the project. Ongoing maintenance is handled during the Frntkey subscription period. Any Centra API changes that require adapter updates are managed by Nordic Web Team as part of the ongoing engagement. This is different from Norce and Shopware where adapter maintenance ships with the base product.

Frntkey with Centra | Backend integration

Frntkey ships native, productized support for Norce Commerce and Shopware. Centra can be connected on a project basis through a custom adapter that maps Centra's API to Frntkey's internal data model. This is real, but it adds adapter development to the project scope compared to the Norce or Shopware baseline.

Benefits

Same storefront, different backend

Frntkey delivers the storefront layer of a headless commerce project regardless of backend. The Nuxt-based frontend, Storyblok CMS, and Nordic vendor integrations are the same on Centra as on Norce or Shopware. Only the commerce adapter changes.

Adapter delivered as project scope

Centra can be paired with Frntkey through a custom adapter built for the specific project. Klarna, Voyado, Lipscore, and the rest of the standard integration set connect through Centra's checkout. Nordic Web Team scopes and delivers the adapter as part of the project.

Productized frontend, custom backend

For merchants committed to Centra with a D2C fashion or multi-market operation, pairing with Frntkey gives a productized frontend without rebuilding the storefront from scratch. The tradeoff versus Norce is added adapter development, not lost storefront capability.

Honest about the alternative

For merchants evaluating platforms rather than committed to Centra, Norce is the natural comparison and comes with the productized Frntkey delivery model. Both are valid choices; the right one depends on the merchant's operational model, not the platform's marketing.

What Centra is

Centra is a Swedish commerce platform focused on direct-to-consumer brands, particularly in fashion and lifestyle. It handles product catalog, pricing across markets, inventory, orders, and merchandising for D2C brands running multi-market operations from Sweden. Its customer base includes a large share of Nordic and European fashion brands who need multi-market retail infrastructure without the operational weight of an enterprise platform.

Centra is API-first by design. The platform does not ship its own storefront — merchants either build a custom frontend against the Centra API or use a productized frontend that supports Centra as a backend. This makes it a natural fit for headless commerce projects, and it puts Centra in the same architectural conversation as Norce Commerce, Shopware, and commercetools.

Where Frntkey fits

Frntkey's native, fully-supported backends are Norce Commerce and Shopware. Both have purpose-built data adapters, pre-tested integration paths for the full Nordic vendor set, and a defined delivery model. Centra is not part of that native set.

Centra can be connected to a Frntkey storefront the same way any API-first commerce engine can: through a custom adapter layer that maps Centra's API to Frntkey's internal data model. This is a project-scope integration, not a productized one. Frntkey ships the storefront, the CMS, and the third-party integrations (Klarna, Voyado, Lipscore); the adapter to Centra is built for the specific project.

The same pattern applies to Shopify (via the Storefront API) and Magento (via GraphQL) — supported on a project basis but not part of the productized backend set.

What that means in practice

A Centra-plus-Frntkey project looks different from a Norce-plus-Frntkey project in a few concrete ways.

Adapter development is project scope. Frntkey has data adapters ready for Norce and Shopware. For Centra, the adapter is built as part of the project. Product, price, cart, checkout, and order APIs each need to be mapped to Frntkey's internal model. This adds time compared to the Norce or Shopware baseline.
Checkout patterns differ. Centra has its own checkout API and its own patterns for handling multi-market pricing, tax, and shipping. Klarna and other payment providers are connected through the Centra checkout rather than through Norce Checkout. The Frntkey storefront renders the checkout UI, but the underlying checkout logic runs against Centra.
Multi-market is different. Centra handles multi-market pricing and inventory as a core part of the platform, in ways that differ from Norce's model. The Frntkey storefront reflects whatever the backend defines. Merchants running Centra get Centra's multi-market model, not a Norce-style one.
Delivery timeline is longer. A Norce-based Frntkey project typically launches in 6 to 12 weeks. A Centra-based project adds adapter development time — typically 4 to 8 additional weeks depending on scope.

Why a merchant might still want this combination

Some merchants have real reasons to stay on Centra as their commerce backend. If Centra fits the operational model (D2C fashion, multi-market inventory, established Centra workflows) and the storefront requirements match what Frntkey delivers (fast Nuxt-based frontend, Storyblok CMS, the Nordic integration set), pairing the two is a reasonable path.

What Frntkey brings to the pairing is the same thing it brings to Norce or Shopware projects: a production-ready storefront in months instead of quarters, a working CMS out of the box, and the Nordic integration set already integrated. The Centra adapter is the added scope.

When Norce might be the better call

For merchants who are evaluating platforms rather than committed to Centra, Norce Commerce is the natural comparison. Both are Swedish, both are API-first, both handle B2C and B2B, and both work well with Frntkey. The differences are real: Centra is stronger in D2C fashion with multi-market inventory; Norce is stronger in mixed B2B/D2C with deep Nordic ERP integration.

If the merchant is a Nordic fashion D2C brand with multi-market operations, Centra fits the profile Centra was built for. If the merchant is a mixed B2B/D2C retailer with Nordic ERP requirements, Norce is the closer fit — and it comes with the productized Frntkey delivery model. The right choice depends on the merchant's operational model, not on which platform has better marketing.

How to move forward

If Centra is committed and Frntkey looks like a fit for the frontend requirements, the conversation is a scoping exercise: what does the Centra adapter need to cover, what's the multi-market model on the storefront side, and how do the Frntkey integrations (Klarna, Voyado, Lipscore) connect through Centra's checkout. Nordic Web Team runs that scoping engagement and delivers the project. Book a demo if this is the path you're considering.
