Klarna Payments for WooCommerce brings Klarna's full Buy Now, Pay Later (BNPL) suite — Pay now, Pay later, and Slice it / Pay in 3-4 instalments — into your WooCommerce checkout, with on-site promotional messaging on product and cart pages that tells shoppers their instalment options before they reach checkout.
Registers a native WooCommerce payment gateway via the WC_Payment_Gateway API, surfacing Klarna's hosted payment categories (Pay now, Pay later, Slice it / Pay in 3-4) directly in checkout
On-site promotional messaging on product, cart and category pages using Klarna's official messaging library, placed via WordPress hooks so it inherits your theme styling
Full EMD (Extra Merchant Data) and order-line payload: line items, SKUs, tax rates, shipping, discounts and customer profile passed for accurate risk assessment and higher approval rates
Capture, refund and partial-capture lifecycle mapped to WooCommerce order status transitions (woocommerce_order_status_completed, woocommerce_order_refunded) — managed entirely from wp-admin
Multi-market support: per-region Klarna credentials, currencies and instalment products, with the correct payment options shown by billing country
HPOS-aware: reads and writes order data through the WooCommerce CRUD/data-store layer so it works with High-Performance Order Storage (custom order tables) and the legacy posts table
This is a build-to-order plugin, not an instant marketplace download. ECOSIRE builds it against your live theme and checkout, installs it on your WordPress site, configures your Klarna merchant credentials (Username/Password or Client ID per region), and supports it after go-live. We register it as a proper WooCommerce payment gateway via the WC_Payment_Gateway API and hook the Klarna Payments session into your checkout flow.
Under the hood we pass complete order-line data and EMD (Extra Merchant Data) — line items, tax rates, shipping, discounts and customer profile — so Klarna can run accurate risk assessment and approve more orders. We wire the full capture / refund / partial-capture lifecycle to WooCommerce order status transitions (woocommerce_order_status_completed, refund hooks) so your finance team manages everything from wp-admin without logging into the Klarna Merchant Portal.
The build is HPOS-aware (WooCommerce High-Performance Order Storage / custom order tables) and works alongside the classic posts table. It supports multi-market Klarna — different credentials, currencies and instalment products per region — and is WPML / multisite-friendly so messaging renders in the right locale. We respect Klarna's on-site messaging library placements rather than hard-coding banners, so updates from Klarna flow through cleanly. Every install is smoke-tested in Klarna's playground before we touch live keys.

A US merchant moving to WooCommerce who had Klarna BNPL before and refuses to lose it. Wants Pay in 4 and financing live with the same approval rates, plus captures and refunds managed from wp-admin.
Runs one WooCommerce store serving Australia and several EU countries with different currencies. Needs region-specific Klarna credentials and instalment products shown by billing country, with WPML-localized messaging.

This is a build-to-order plugin, so there is no instant download. Typical delivery is 3 to 7 business days from when we receive your Klarna playground credentials and WordPress/WooCommerce access. We build the gateway against your actual theme and checkout, install and configure it on your site, test the full purchase/capture/refund flow in Klarna's playground, then cut over to your live keys after your sign-off. Complex multi-market or block-checkout setups may add a few days — we confirm the timeline before starting.
Every build includes a defined post-launch support window for bug fixes and configuration help. Because the plugin is custom to your site, updates are handled by ECOSIRE rather than auto-pushed from a marketplace — when WooCommerce, WordPress or Klarna's API changes (for example a new HPOS requirement or a messaging-library update), we update your plugin under a maintenance arrangement so it keeps passing Klarna's certification. We agree the scope and duration of support in writing before delivery.
Yes. We build against the WooCommerce CRUD/data-store layer rather than reading wp_posts directly, so the plugin is compatible with High-Performance Order Storage. We support both the classic shortcode checkout and the newer Checkout block — tell us which your store uses (or both) and we target it during the build. We verify HPOS compatibility as part of installation.
Yes. The plugin supports per-region Klarna credentials, currencies and instalment products (Pay in 3, Pay in 4, financing) so the right options appear based on the shopper's billing country. This is one of the most common reasons merchants come to us instead of a one-size-fits-all plugin — multi-market routing and locale-correct messaging are configured as part of your build.
Yes, and it matters. We pass complete order-line data (line items, SKUs, tax, shipping, discounts) plus Extra Merchant Data and customer profile in the Klarna session payload. Accurate, complete data is what lets Klarna run a proper risk assessment and approve more orders — incomplete payloads are a common cause of declined or failed Klarna sessions, so we make sure yours is right.
