Mollie Payments for WooCommerce (Pro)

Key Features

Each Mollie method registered as a native WC_Payment_Gateway so iDEAL, Bancontact, SOFORT, Giropay and EPS render directly on the WooCommerce checkout

iDEAL bank-selector and Bancontact handled with method-specific availability rules by billing country, store currency and cart total

SEPA Direct Debit plus SEPA credit transfer (bank-transfer) with mandate handling and pending-order status until funds clear

Klarna and in3 buy-now-pay-later surfaced through your existing Mollie contract — no second BNPL integration

Hosted Mollie checkout (PSD2/SCA-compliant redirect) or embedded Mollie Components card fields rendered inside your own checkout page

Mollie webhook bound to a dedicated WooCommerce REST API endpoint so payment status updates even if the shopper abandons the redirect tab

WC-Cron reconciliation job that re-queries the Mollie API for any late or missed webhook so no paid order is left on hold

Refunds, partial refunds and manual captures driven from the WooCommerce Edit Order screen via the Mollie Orders/Payments API

HPOS / custom-order-tables ready and verified against both block-based and classic shortcode checkout

WPML and WordPress multisite aware — method titles and descriptions translatable, per-site Mollie API keys

Test-mode vs live-mode toggle in wp-admin with separate Mollie API keys and a guided go-live verification

Order-status mapping (pending, on-hold, processing, completed, failed, cancelled) configurable per method via WordPress filters

About this Product

European checkout fails when your only options are Stripe and PayPal. Dutch shoppers expect iDEAL, Belgians expect Bancontact, Germans reach for SOFORT, Giropay and EPS — and skip the cart when those buttons aren't there. This is a build-to-order WooCommerce gateway: ECOSIRE builds, installs and configures a Mollie-powered payment plugin directly on your WordPress site, then supports it. There is no marketplace download — you buy the build, we deliver it onto your store.

The plugin registers each Mollie method as a proper WC_Payment_Gateway subclass so methods appear natively on the WooCommerce checkout, respect your payment-method ordering, and honour per-method availability rules (country, currency, cart total). We wire Mollie's webhook to a dedicated WooCommerce REST endpoint so order status stays in sync even when a customer closes the tab mid-payment — the WC-Cron fallback reconciles any webhook the bank delivers late.

You get hosted checkout (redirect to Mollie's PSD2-compliant page) or Mollie Components (embedded card fields rendered inside your checkout, no full redirect). SEPA Direct Debit, credit transfer, and Klarna / in3 BNPL through your existing Mollie contract are included. Refunds, partial refunds and captures are driven straight from the WooCommerce Edit Order screen via the Mollie API — no logging into a separate dashboard.

Everything is built HPOS-ready (custom order tables), tested against your active theme and checkout (block or classic/shortcode), and WPML / multisite-aware if you run multilingual or multi-store. You own the code on your server. ECOSIRE handles the build, the Mollie API onboarding handshake, go-live verification, and ongoing support.

What you get

A custom Mollie gateway plugin built and installed on your WordPress / WooCommerce site

Mollie API onboarding handshake configured — live and test API keys wired with the webhook endpoint registered

Selected payment methods (iDEAL, Bancontact, SOFORT, Giropay, EPS, SEPA, Klarna/in3) enabled and ordered on checkout

HPOS, theme and block/classic-checkout compatibility verified on your actual store

A documented go-live test: real test-mode transaction, refund and webhook sync confirmed end to end

Short admin handover doc covering wp-admin settings, refunds from Edit Order, and test/live toggle

Defined post-launch support window for fixes, WooCommerce/WordPress compatibility and questions

Who this is for

Dutch / Belgian WooCommerce merchant

Runs a NL or BE store losing carts because iDEAL and Bancontact aren't offered. Needs the methods local shoppers trust as native checkout buttons, not a clunky redirect afterthought.

German DACH online retailer

Sells into Germany and Austria where SOFORT, Giropay, EPS and SEPA bank transfer dominate. Wants one Mollie integration covering all of them plus Klarna BNPL instead of stitching several plugins together.

Agency or developer serving EU clients

Builds WooCommerce stores for European clients and needs a clean, HPOS-ready, WPML-aware Mollie gateway delivered and supported, without burning internal hours on gateway plumbing and webhook edge cases.

Frequently Asked Questions about Mollie Payments for WooCommerce (Pro)

How long until it's live on my store? What's the delivery lead time?

This is build-to-order, not an instant download. After purchase and a short kickoff to collect your Mollie account access and staging/site details, typical delivery is around 5 to 10 business days depending on how many payment methods you need and your checkout complexity. We confirm a firm date at kickoff and deliver onto your WordPress site, not as a marketplace ZIP you self-install.

What happens after launch — do I get support and updates?

Yes. Every build includes a defined post-launch support window for bug fixes, plus compatibility maintenance as WooCommerce, WordPress and the Mollie API evolve. Because the plugin is installed on your own server you own the code; ECOSIRE provides the ongoing fixes, SCA/PSD2 compliance updates and method changes. Longer-term support and retainer options are available if you want continuous coverage.

Do I need my own Mollie account?

Yes — you sign your own contract with Mollie and own the merchant relationship, settlements and pricing. We use your live and test API keys to configure the gateway. The methods you can offer (iDEAL, Bancontact, Klarna, in3, etc.) depend on what Mollie has activated on your account; we enable and order whatever is approved.

Will it work with HPOS and the new block-based checkout?

Yes. The gateway is built HPOS-ready against WooCommerce custom order tables and we verify it on your actual checkout, whether you run the block-based Checkout or the classic shortcode page. We test the redirect (hosted) and embedded Mollie Components paths against your live theme before go-live.

How do refunds and webhooks work?

Refunds and partial refunds are issued straight from the WooCommerce Edit Order screen via the Mollie API — no separate dashboard login. Payment status is kept in sync by a Mollie webhook bound to a dedicated WooCommerce REST endpoint, with a WC-Cron reconciliation job that re-queries Mollie for any webhook delivered late, so a paid order never stays stuck on hold.
