What is the Mollie billing integration?
The BillingServ Mollie integration adds Mollie payment methods to your customer checkout. Mollie handles the payment flow, while BillingServ keeps the amount, currency, customer, invoice and order reference together.
Available methods are checked against the payment amount, currency and billing country, so customers see the Mollie options that are enabled for the checkout in front of them.
One gateway, more ways to pay
Use Mollie Components for secure card entry, or offer iDEAL, SEPA bank transfer, Bancontact and Klarna where Mollie makes them available for the transaction.
Mollie callbacks prompt BillingServ to retrieve and validate the payment result. Paid invoices and transaction records update without your team matching gateway references by hand.
Mollie payments connected to the full billing cycle
Give customers familiar payment choices without separating payment collection from invoicing and account management.
Cards through Mollie Components
Collect card details through Mollie tokenisation and keep sensitive card entry out of your BillingServ forms.
iDEAL payments
Offer Dutch customers iDEAL when it is enabled and available for the invoice currency and amount.
SEPA bank transfer
Give eligible customers a bank transfer route while the invoice remains connected to the Mollie payment.
Bancontact and Klarna
Add Belgian bank payments and flexible Klarna payment options through the same configured gateway.
Saved cards
Customers can save a card, select it again for a later payment and remove it from their payment methods.
Verified payment updates
BillingServ validates the payment ID, customer, amount, currency and method before recording a successful result.
Connect Mollie once, then take payments from BillingServ
Setup is kept inside your payment integration settings and customer checkout.
Add your Mollie details
Enter your Mollie API key and profile ID, then add the BillingServ webhook URL in your Mollie settings.
BillingServ checks availability
The checkout asks Mollie which enabled methods support the invoice amount, currency and billing country.
The customer pays
They choose an available method, complete the Mollie flow and can save a card for later when using card payment.
The invoice is updated
BillingServ verifies the callback and records the confirmed payment against the correct customer and invoice.
Mollie handles the transaction. BillingServ handles what comes around it.
A gateway is good at moving money. Your billing platform still needs to know what was sold, which invoice was paid and what the customer should see next.
The Mollie integration keeps those responsibilities connected without blurring them. Customers get the payment method, while your team keeps a usable billing record.
Local payment methods
Offer supported European methods through one Mollie connection instead of maintaining a separate billing workflow for each one.
Cards for returning customers
Valid Mollie card mandates can be selected again, reducing repeat data entry for future payments.
Test before going live
Use Mollie test mode to check your checkout and callback setup before taking live payments.
Records that match
Payment validation checks the invoice context before BillingServ marks a transaction as paid.
Mollie integration questions
What BillingServ customers need to know before connecting Mollie.
What payment methods does the BillingServ Mollie integration support?
The current release supports credit and debit cards, iDEAL, SEPA bank transfer, Bancontact and Klarna. The methods shown at checkout depend on what is enabled in Mollie and available for the payment amount, currency and billing country.
Can customers save a card with Mollie?
Yes. Authenticated customers can save a card, choose a valid saved card for a later payment and remove it from their BillingServ payment methods.
Does BillingServ store raw Mollie card details?
No. Card fields use Mollie Components to tokenise the card. BillingServ works with the resulting Mollie customer and mandate references rather than storing the raw card number.
Can a saved Mollie card be used for repeat payments?
Yes. BillingServ can submit a later payment using a valid Mollie card mandate selected for that customer.
How does BillingServ confirm a Mollie payment?
BillingServ receives the Mollie callback, retrieves the payment and checks its payment ID, customer, reference, amount, currency and method before recording it as paid.
Can I test the Mollie integration before taking live payments?
Yes. The integration supports Mollie test mode so you can check card tokenisation, payment methods and webhook handling before switching to live credentials.
What do I need to connect Mollie?
You need an active Mollie account, a Mollie API key and a Mollie profile ID. BillingServ provides the webhook URL to add to your Mollie configuration.
