Mollie

Can your business offer the payment methods your customers use?

Mollie lists businesses based in the European Economic Area, Switzerland and the UK. It asks for an IBAN, an international bank account number, or a UK bank account. Check which methods are available for your business and customers before you build around one.

Your business sells the product and Mollie handles the payment. Register your sales website, complete business verification for payouts and check each required method’s status. Card payments, Klarna and SEPA Direct Debit can require additional checks.

What should customers see if they come back before payment is confirmed?

Show a waiting message with the order still unpaid. Mollie can return a visitor to your site before its status notification arrives. Your server can check the payment directly with Mollie and release the purchase when it confirms the payment is paid.

For a paid workshop, create a payment from your app’s order, save Mollie’s payment reference and send the customer to the checkout address Mollie returns. When Mollie calls your webhook, the address where your server receives updates, look up that payment from your server. Match it to the order and confirm the amount and currency before granting workshop access.

Why can a refund be queued after you request it?

Mollie takes the refunded amount from your balance. A refund can wait there for enough money. Refunds have a status of their own, so the original payment can still appear paid while a refund is being processed. Check support for the original payment method. Some gift cards and other methods cannot be refunded through Mollie.

If your app sends a refund request but the connection times out before it gets an answer, keep the refund marked as uncertain and turn off automatic retries for that request. Look up the original payment’s refunds in Mollie’s dashboard or have your server check them with Mollie. If you still cannot tell whether Mollie created it, leave the request for review instead of sending another one.

How can you see whether your workshop access follows the payment?

Before opening checkout, confirm that the app copy uses Mollie’s test API key and that its actual return address, webhook address, orders, workshop access and email all point to disposable services. Use a fictional workshop and the hosted test checkout. If you cannot confirm the setup, map the outcomes on paper and inspect the configured destinations without submitting.

1. 1
   Make one test payment succeed

   Choose a paid test outcome. Confirm the provider’s test status and check that the matching fictional account receives one workshop pass. A visit to the return page alone should leave an order waiting until the app knows its status.
2. 2
   Keep an unsuccessful purchase closed

   Create a separate test order and choose a failed or canceled outcome. Check that no pass appears for that order and that the paid sample still has its pass.
3. 3
   Compare the payment and refund

   Use the paid test payment’s change-state page to simulate a refund. Verify the refund in the test records and check your app applies the workshop’s refund rule. A refund record and access removal are separate things to confirm.

When does a sale show up in your bank records?

There are two waits to check. First the payment method has to make the money available in your Mollie balance. Then your payout schedule and bank determine when it reaches your account. Use the dashboard’s estimated next payout to plan for that gap.

Standard online rates depend on the country, payment method and card type. On November 12, 2026, Mollie’s UK table listed 1.20% plus £0.20 for an online UK domestic consumer Visa or Mastercard transaction. That is a UK example. Check your local rate and any payout or conversion charges that apply.

Download the balance or settlement report for bookkeeping and keep your own orders and access records. Mollie says its exports exclude PayPal transactions and refunds. If you enable PayPal, collect those records separately when reconciling sales.
