About this Product
Klarna BNPL for Shopify brings the world's largest buy-now-pay-later provider to your storefront with Pay in 4 interest-free installments and longer-term Pay Monthly financing — the lever mid-to-higher-ticket stores use to lift average order value and rescue carts that stall at the price tag. You stay paid upfront in full; Klarna assumes the credit and fraud risk on every approved order.
Why Choose Klarna BNPL for Shopify

Klarna **Pay Monthly** longer-term financing for higher-ticket carts
On-site **BNPL messaging widgets** on product detail pages showing per-installment pricing

This is not an instant App Store install. ECOSIRE builds the integration to order, wires it into your specific theme and checkout, and hands you a tested, production-ready setup. We connect your Klarna Merchant account to Shopify, register Klarna as an additional payment method, and place on-site messaging widgets ("As low as $X/mo with Klarna") on product and cart pages so shoppers see installment pricing before they reach checkout — where it actually moves conversion.
Under the hood we use the Shopify Admin GraphQL API and a custom Theme App Extension (app embed + app blocks) so the messaging components survive theme updates instead of being hard-coded into Liquid. Order and refund webhooks keep Klarna settlement and your Shopify order records in sync, and we expose conversion/AOV reporting so you can see BNPL's real revenue impact rather than guessing.
We handle multi-market support across US and EU — Klarna's product availability, currency, and consumer-credit messaging rules differ by country, so each market is configured to display the correct plan and legally-required disclosures. Built for Shopify Plus and standard Shopify, installed by us, and supported after launch. You provide the Klarna merchant credentials and theme access; we deliver a clean, conversion-focused BNPL experience.

Frequently Asked Questions about Klarna BNPL for Shopify
+How long does it take to build and install?
A standard single-market build typically delivers in 5 to 10 business days from the point we receive your Klarna merchant credentials and theme access. Multi-market US and EU setups, custom widget placements, or Shopify Plus checkout customizations add time. We confirm an exact timeline in writing before we start — this is a build-to-order service, not an instant download.
+Do I need my own Klarna merchant account?
Yes. Klarna underwrites the consumer credit and pays you upfront, so the commercial agreement is between you and Klarna. You sign up for a Klarna Merchant account and provide us the API credentials; we handle all the Shopify-side integration, configuration, and on-site messaging. We can advise during your Klarna onboarding if needed.
+What ongoing support and updates are included?
Every build includes a post-launch support window for bug fixes and adjustments. Because we use a Theme App Extension rather than hard-coded Liquid, the messaging widgets generally survive Shopify theme updates. For ongoing changes — new markets, Klarna product updates, redesigns — we offer a maintenance arrangement billed separately. You are never locked out; we hand over full documentation.
+Will I really get paid upfront, or do I wait for the customer's installments?
You are paid the full order amount upfront (less Klarna's merchant fee) once Klarna approves the order. The customer pays Klarna over time in Pay in 4 or Pay Monthly installments, and Klarna — not you — carries the credit and fraud risk. The integration records the order and settlement in Shopify so your reporting stays accurate.
+Does it work for multiple countries and currencies?
Yes — we support multi-market configuration across the US and EU. Klarna's available plans, currencies, and legally-required credit messaging differ by country, so we configure each storefront to show only its eligible Klarna products and the correct disclosures. If you operate beyond US/EU, tell us your markets and we'll scope Klarna availability for them.
