Companies Using Klarna Checkout

The one payment method where America is not the biggest market

Every payment technology we have profiled shows the same geographic shape: the United States first, usually by a wide margin, with the United Kingdom and Canada trailing. Shop Pay is 48.70% American. Klarna Checkout is not.

The United Kingdom leads at 20.78% of matched merchants, Germany follows at 16.93%, Italy takes 8.19%, and the United States ranks fourth at 8.14%. France, the Netherlands and Spain follow, with Klarna's home market of Sweden at 3.87%. On our data this is a European payment network that also operates in America, rather than a global one headquartered in Stockholm.

That distribution has a regulatory explanation as much as a commercial one. Instalment credit at the point of sale sits inside consumer credit rules that differ sharply by jurisdiction, and Klarna built its merchant base market by market across Europe over more than a decade. The American footprint is real but comparatively recent, and the crawl shows it has not yet caught the European core.

The United States is Klarna Checkout's fourth-largest market, behind the UK, Germany and Italy. No other payment method we track has that shape.

Two Klarna entries, and only one of them is Klarna

Anyone comparing this page against our buy-now-pay-later data will find a contradiction worth explaining, because it is a measurement artefact rather than a fact about the market.

Our corpus carries a separate, narrower Klarna entry filed under Buy Now Pay Later. It matches a single signal, the Klarna Payments SDK, and reaches roughly 900 domains. This page's entry matches six independent signals, including Klarna's session cookies, two JavaScript objects, the checkout button element and a content security policy naming Klarna's own hosts, and reaches 191,675. The two sets share only 215 domains.

The consequence is that any ranking built on the narrower entry understates Klarna by more than two orders of magnitude, and a buy-now-pay-later comparison drawn from it would put Klarna far below competitors it plainly outweighs. The figure on this page is the one that reflects Klarna's deployed merchant base.

A small-merchant product with famous logos on top

The named list opens with Airbnb, Decathlon, Lululemon, Coach, Tommy Hilfiger, Forever 21 and two American auto-parts chains. The distribution underneath tells a different story: 78.88% of matched merchants have ten or fewer employees, 93.74% have fewer than fifty, and only 0.59% exceed a thousand.

Both are true and the combination is the point. Klarna's commercial position rests on a very long tail of small direct-to-consumer retailers, while its brand recognition rests on a short list of large ones. For anyone using this list to sell, those are two entirely different segments with different budgets, buying processes and needs, and treating the 47,662 identified merchants as one audience would be a mistake.

The basket is discretionary, and that is the whole business

Retail leads at 19.54%, with apparel and fashion at 10.71% and luxury goods and jewellery at 3.97%. Personal care manufacturing takes 3.05% and sporting goods 2.35%. Together the discretionary consumer categories exceed 39% of matched merchants.

What is absent matters as much. Groceries, utilities and essential services barely register. Instalment payment changes a purchase decision when the basket is large and the purchase is optional, which is precisely the fashion, beauty and sporting goods profile the data shows. A merchant selling weekly essentials has no reason to offer it, and the distribution reflects that with unusual clarity.

Mastercard and Visa each appear on 93.40% of Klarna Checkout storefronts. Payment methods are not alternatives to one another, so this page publishes no switching table.

Why there is no migration section

The obvious analysis for a payment page is which providers merchants move between, and we do not publish one here for the same reason we did not for Shop Pay.

Mastercard and Visa each appear on 93.40% of Klarna Checkout domains, Apple Pay on 91.53% and American Express on 83.91%. A checkout page presents these together, and enabling one does not disable another. Any corridor computed from this data would be counting stores that stopped trading, or pages our crawler rendered differently on a later visit, and labelling it competitive displacement. That matches our earlier review of payment corridors across 51 pairs, in which 50 proved to be coexistence and none were migrations.

This is a Shopify story

Shopify appears on 95.76% of Klarna Checkout domains and Cloudflare on 97.65%, the latter being Shopify's own infrastructure rather than a merchant choice. Klarna Checkout is, in practice, a Shopify app installation for the overwhelming majority of these merchants.

Facebook Pixel on 47.38% completes the picture, and it is the most useful row for anyone selling into this list. These are performance-marketing-driven direct-to-consumer retailers acquiring customers through paid social, where instalment options lift conversion on higher-value baskets. Google Tag Manager at 53.86% and Google Analytics at 53.37% both sit below our corpus norm, which is the familiar Shopify pattern of merchants relying on built-in reporting. TechnologyChecker.io publishes 191,675 as a floor on live deployments, and the jump from 88,845 in June reflects our detection reach widening across those months rather than the merchant base doubling.
