Mollie Payments and Recurring for WHMCS
Take every payment method in your Mollie account in WHMCS, from iDEAL and Wero to Bancontact and cards, and charge renewals automatically through Mollie mandates.
What will the Mollie gateway do?
It connects WHMCS to your Mollie account with all the payment methods you have switched on there. At checkout the client picks a method and pays on Mollie's page. For card or bank payments that allow it, that first payment also creates a mandate, and WHMCS then charges each renewal invoice automatically. Refunds start from the WHMCS invoice, and Mollie's webhooks update the invoice once, even when Mollie sends the same notice twice.
This product is built to order: you get the license key at purchase and the download within 15 business days.
Why do WHMCS sellers in Europe need it?
iDEAL, the main way people in the Netherlands pay online, is moving to Wero, with merchants switching from the last quarter of 2026. Mollie lets you turn Wero on in its dashboard, so a gateway that shows whatever methods your Mollie profile has follows that change without a new module.
What does WHMCS already do, and what does this add?
WHMCS includes an "iDeal via Mollie" gateway for one-time iDEAL payments. It does not offer Mollie's other methods, automatic renewals or refunds from WHMCS. Older third-party Mollie modules on the Marketplace list WHMCS 8 as their latest tested version. This gateway adds all enabled methods, mandates for renewals, refunds and stored payment methods on WHMCS 8.13 and 9.
What is included?
| Part | What you get |
|---|---|
| Methods | Every method enabled in your Mollie profile, such as iDEAL, Wero, Bancontact, cards, SEPA bank transfer and Przelewy24 |
| Renewals | A mandate from the first payment, used to charge renewal invoices automatically |
| Stored methods | The mandate shown as a payment method in the client area, removable by the client |
| Refunds | Full and partial refunds from the WHMCS invoice |
| Webhooks | Each payment applied once, with a log of every notice |
Who is it for?
Hosting companies and software sellers in the Netherlands, Belgium, Germany, France, Poland and Italy that use Mollie or want to.
What do you need, and what are the limits?
Requirements: WHMCS 8.13 or 9.x (I confirm your exact version at purchase), PHP 8.1 or newer, and a Mollie account with an API key. Renewals from bank payments need SEPA Direct Debit switched on in your Mollie profile.
Limits: not every method can create a mandate; clients who pay with one that cannot receive the renewal invoice by email as usual. Mollie's documentation does not yet cover recurring payments through Wero. Mollie's own fees apply.
It costs $99 once for a lifetime license with twelve months of updates and support, the license key at purchase and the download within 15 business days, and a seven-day refund window.

Frequently asked questions
Does it support Wero?
For one-time payments, yes: once Wero is switched on in your Mollie dashboard, it appears at checkout. Mollie's documentation does not yet cover recurring payments through Wero, so renewals for those clients use the invoice email until it does.
How do automatic renewals work?
The first payment by card or a bank method that supports it creates a Mollie mandate. When WHMCS creates the next invoice, the gateway charges it through that mandate. Clients can remove the stored method in the client area at any time.
When will I get it, and what if you can't deliver?
You get the license key at purchase and the download within 15 business days of purchase. If I do not deliver it in that time, you get a full refund. Otherwise the store's seven-day refund window applies.
