Key Features
Native Odoo payment provider: extends payment.provider with a 'klarna' code and dedicated payment.transaction flow, so Klarna appears alongside card and bank acquirers in eCommerce, Sales portal and invoicing
Three purchase modes at checkout — Pay now, Pay later (invoice), and Pay in installments (Pay-in-3/4) — surfaced as selectable Klarna methods on the payment step
On-site promotional messaging widget rendered via QWeb/OWL on product and cart pages, driven by the live cart total, configured locale and currency
Redirect to Klarna Hosted Payment Page (or embedded session) with return handled by a dedicated Odoo controller that syncs transaction state on landing
Webhook reconciliation controller that verifies Klarna callbacks, matches by transaction reference, and moves the transaction to authorized/done/cancel/error even when the shopper drops off
Order management from inside Odoo: capture-on-shipment, partial and full refunds, and cancellation posted back to Klarna's Order Management API, logged to chatter
Multi-currency EU support (EUR, SEK, DKK, NOK, GBP, PLN and more) with per-country Klarna method availability rules
Test and production credential toggle on the provider record, with secrets referenced via ir.config_parameter and never exposed in the DOM
Automatic invoice / sale.order state alignment — successful authorization confirms the order and lets your standard account.move workflow proceed unchanged
Access control via ir.model.access.csv plus record rules restricting capture/refund/cancel actions to authorized accounting or sales roles
Automated actions (server actions / scheduled ir.cron) to reconcile stale 'authorized' transactions and flag mismatches for review
Structured logging and an audit trail of every Klarna request/response on the transaction, so failed authorizations are debuggable, not silent
Fraud- and eligibility-aware handling: gracefully falls back to other configured providers when Klarna declines or is unavailable for the shopper's country/currency
Optional XML-RPC/JSON-RPC exposure so external OMS or POS systems can trigger captures and read Klarna transaction status
Works on Odoo 17, 18 and 19, Community or Enterprise, with the provider styled to match your website theme
About this Product
Give your European customers the Klarna options they now expect at checkout — pay now, pay later, or pay in installments — without leaving Odoo. This is a build-to-order module engineered by ECOSIRE and installed on your Odoo 17, 18 or 19 instance (Community or Enterprise). It is not an instant apps.odoo.com download; we build it to fit your acquiring setup, your regions and your reconciliation workflow, then hand you the code.

Order management from inside Odoo: capture-on-shipment, partial and full refunds, and cancellation posted back to Klarna's Order Management API, logged to chatter
At its core the module is a native Odoo payment provider. It extends payment.provider with a klarna code and its own payment.transaction handling, so Klarna behaves like any other acquirer across eCommerce checkout, the Sales portal ("pay online") and invoicing. Customers are redirected to Klarna's Hosted Payment Page (or an embedded session, depending on your plan), authorize the order, and land back on the Odoo confirmation page with the transaction state synced. Because it uses the standard provider abstraction, your existing sale.order → account.move flow, sales teams and reporting stay exactly as they are.
Under the hood we implement the Klarna Payments and Order Management APIs against your credentials, stored on the provider record and referenced by ir.config_parameter where appropriate. Server-to-server calls are made from Python controllers; every state change from Klarna arrives on a public webhook controller that verifies the payload, matches it to the right payment.transaction by reference, and moves the transaction to authorized, done, cancel or error. That gives you truthful order states even when a shopper closes the tab mid-flow — no more "paid in Klarna, pending in Odoo" mismatches.
On-site messaging is included: a QWeb/OWL promotional widget renders Klarna's "3 interest-free payments of €X" placement on product and cart pages, driven by the live cart total and your configured locale and currency, so the offer your shopper sees matches what Klarna will actually approve. Merchant operations are first-class too — capture on shipment, partial or full refunds, and cancellations are exposed as buttons and server actions on the order/invoice, writing back to Klarna's Order Management API and logging the result to the chatter.
The build covers multi-currency EU operation (EUR, SEK, DKK, NOK, GBP, PLN and more), per-country method availability, test/production toggle, and access control via ir.model.access.csv plus record rules so only authorized users can capture or refund. You get the full module source, a configuration handoff, admin documentation and a support window — delivered in 2–4 weeks and supported afterward.

Who this is for
European D2C / eCommerce retailer
Runs an Odoo Website Shop selling into the Nordics, DACH, Benelux or UK and knows Klarna 'Pay in 3' at checkout lifts conversion and average order value. Wants the option live natively in Odoo without bolting on a separate storefront.
Head of Finance / Accounting manager
Needs Klarna settlements, captures and refunds to reconcile cleanly against account.move and bank statements. Cares that webhook-driven transaction states are truthful and that capture/refund rights are locked down by role.
Odoo functional consultant / integration partner
Implements Odoo for a merchant and needs a payment provider that follows the standard payment.provider/payment.transaction pattern, ships as a proper addon, and works across 17/18/19 without hacking core — so it survives upgrades.

How Klarna BNPL Gateway for Odoo (Europe) Compares
| Criterion | ECOSIRE | Custom Build | Competitor | Odoo Native |
|---|---|---|---|---|
| Native Odoo payment provider (payment.provider / payment.transaction), survives upgrades | Built as a standard provider addon for 17/18/19 | Depends entirely on the developer's discipline | Usually yes, but tied to that vendor's release cadence | |
| Klarna pay-in-3 / pay-later / financing at checkout | All three modes, mapped per country/currency | Whatever you scope and pay to build | Often only some modes, region-limited | |
| On-site promotional messaging widget (live cart total, locale-aware) | Included via QWeb/OWL on product and cart pages | Extra build effort, frequently skipped | Sometimes; often static or not cart-aware | |
| Webhook reconciliation for truthful transaction states | Verified webhook controller + scheduled reconciliation action | Commonly the piece that gets under-built | Varies by vendor quality | |
| Capture / refund / cancel from inside Odoo via Order Management API | Buttons/server actions with role-based record rules | Only if explicitly scoped | Sometimes; refund coverage varies | |
| Multi-currency EU coverage (EUR, SEK, DKK, NOK, GBP, PLN…) | Configured to your target markets | Whatever you build | Often a fixed subset | |
| Fit to your acquiring setup, roles and reconciliation workflow | Scoped and tailored to your business | Fully bespoke but you carry all risk | One-size-fits-all configuration | |
| Delivery, install, docs, training and support included | Built, installed and supported by ECOSIRE | Only what your contract covers | Self-serve; support is add-on/limited |
Frequently Asked Questions about Klarna BNPL Gateway for Odoo (Europe)
+How long does delivery take, and what happens after I purchase?
This is a build-to-order module, not an instant download. Typical delivery is 2–4 weeks depending on your Klarna acquiring setup, target countries and currencies. After purchase we schedule a short scoping call, collect your Klarna sandbox/production credentials and requirements, build and test the addon against your Odoo version, install it on your instance, verify live test transactions, then hand over the source code and documentation.
+What support and updates do I get after go-live?
You get a defined post-delivery support window covering bug fixes, configuration help and Odoo/Klarna compatibility questions. Because you receive the full module source, you own the code outright. We can also arrange an ongoing maintenance agreement to keep the module aligned with future Odoo releases (17→18→19) and Klarna API changes.
+Which Odoo versions and editions are supported?
Odoo 17, 18 and 19, on both Community and Enterprise. The module is built as a standard payment provider extending payment.provider and payment.transaction, so it integrates with Website eCommerce checkout, the Sales portal 'pay online' flow and invoicing without modifying Odoo core.
+Do you host it, or does it run on my own Odoo?
It runs on your Odoo instance — Odoo Online (SaaS) generally cannot run custom addons, so this targets Odoo.sh, self-hosted, or ECOSIRE Managed Hosting. If you're on Odoo Online we'll advise on the migration path during scoping.
+Which currencies and countries can Klarna handle here?
The module supports multi-currency EU operation (EUR, SEK, DKK, NOK, GBP, PLN and others) with per-country method availability, since Klarna's available options (pay-in-3, pay-later, financing) differ by market. Your final country/currency matrix is confirmed during scoping and mapped to the on-site messaging and checkout logic.
+What if a customer's payment fails or they abandon Klarna mid-flow?
Transaction state is driven by Klarna webhooks, not just the browser redirect. A verified webhook controller matches each callback to its payment.transaction by reference and sets authorized/done/cancel/error accordingly, and a scheduled reconciliation action flags stale transactions. If Klarna declines or is unavailable for the shopper, checkout gracefully falls back to your other configured providers.
+Can we capture, refund and cancel Klarna orders from inside Odoo?
Yes. Capture-on-shipment, partial/full refunds and cancellations are exposed as buttons/server actions on the order and invoice, posting back to Klarna's Order Management API and logging the result to chatter — with access restricted to authorized roles via record rules.
