Walley Payment: Full Checkout Suite for Nordic eCommerce

Walley is the Nordics' second largest payment provider, backed by Norion Bank and serving over 6.5 million active users across Sweden, Norway, and Finland. The company — formerly Collector — offers a modular checkout covering invoice, part-payment, account payment, Swish, Vipps, MobilePay, and card. It serves both B2C and B2B, online and in-store, with an omnichannel approach that connects the checkout experience across sales channels.

For ecommerce merchants in the Nordic mid-market and above, Walley occupies a distinct position: a checkout provider with its own consumer user base, loyalty features, and shipping integration — all backed by a bank. But how Walley performs inside your store depends on the ecommerce platform, the integration architecture, and the delivery work around it.

Where Walley sits in the stack

Walley Checkout is modular. It breaks the checkout into components: identification (recognising returning shoppers across the Walley network), shipping (presenting carrier options based on cart and address), and payment (invoice, card, Swish, part-payment, account). Merchants choose which modules to use and how they appear in the checkout flow.

The identification module is particularly relevant: Walley recognises millions of existing users from other merchants in the network, pre-filling address and payment details. For returning shoppers, this reduces checkout steps significantly. For new customers, validation services handle registration.

Everything outside the checkout — product catalogue, pricing, cart logic, order management, fulfilment — stays with the ecommerce platform and the ERP. The integration between Walley and these systems determines whether checkout performance translates into clean orders and correct settlement.

Walley across platforms

On Shopify, Walley offers a dedicated app with multicurrency support. Nordic merchants on Shopify can sell in SEK, NOK, DKK, and EUR from a single store. The integration handles payment methods per market and connects to Walley's settlement infrastructure.

On Shopware, Walley integrates through the payment plugin layer. Shopware's flexible checkout gives control over how Walley's modules interact with shipping, promotions, and order management. Multi-market configurations can show different payment options per country.

On Norce, Walley connects through the commerce engine's payment layer. Norce's strength in complex product data and B2B flows pairs with Walley's B2B checkout capability, enabling business and consumer buyers in the same store.

On Magento/Hyvä, Walley provides integration for the full checkout module set. Hyvä's lightweight frontend improves page performance around the checkout, while Walley handles the payment and identification flow in its own layer.

Invoice, account, and loyalty

Walley's invoice and account payment products are among the most used in the Nordics. Invoice lets customers pay after delivery — 14 or 30 days. Account payment consolidates multiple purchases into a single monthly statement, with the option to pay in full or split. Part-payment spreads cost over 3–36 months.

For merchants, these payment methods influence average order value and repeat purchase rates. The account model in particular creates a recurring relationship between the customer and the merchant, mediated through Walley. Loyalty features and gift cards extend this further.

The trade-off: these products involve consumer credit, which means Walley performs credit checks at checkout. How this interacts with the checkout UX — approval speed, rejection handling, fallback methods — needs to be designed and tested as part of the implementation.

B2B checkout without registration

Walley's B2B checkout allows business customers to pay by invoice without separate registration or minimum order requirements. The buyer enters company details, Walley performs a credit check, and the transaction proceeds. For merchants with mixed B2C/B2B audiences, this removes a common friction point.

The ecommerce platform needs to correctly pass buyer type context to Walley. If company identification data does not flow into the checkout reliably, B2B payment methods may not appear when they should.

Walley and the ERP connection

Settlement data from Walley — invoice payments, card captures, refunds, account statements — needs to reach the ERP. For Nordic merchants on Fortnox, Visma, or Business Central, Junipeer can handle the middleware layer. Settlement reconciliation is important because Walley handles multiple payment types with different settlement cycles, and the ERP needs to track each correctly.

When Walley fits — and when to complement it

Walley is a strong choice for Nordic merchants — particularly in Sweden, Norway, and Finland — who want a checkout with a built-in consumer user base, invoice and account payment products, and omnichannel capabilities. The modular design lets merchants start with the components they need and expand later.

For expansion beyond the Nordics, complementary providers are often needed. Adyen covers global markets. Mollie adds depth in Benelux and DACH. For dedicated payment orchestration with multiple providers, Briqpay takes a different approach. Klarna is the main competitor in Nordic BNPL with higher consumer brand recognition, though Walley's account model and loyalty features differentiate it for merchants focused on repeat purchase.

Beyond the integration

Connecting Walley is one deliverable. The surrounding work includes platform selection, checkout module configuration, shipping integration inside the checkout, credit check UX design, ERP data flow mapping, QA across payment methods and edge cases, and rollout planning. An omnichannel setup — connecting online and in-store payments through the same provider — adds further integration scope that needs to be planned from the start.
