How does the Mollie integration work?

Mollie is a platform that makes it easy for organisations to receive online payments. These online payments can be made via a payment link or a QR code.
Our direct integration with Mollie makes it possible to use this in Robaws.

To set up an integration with Mollie, you need to have an account with Mollie. That is not something we provide.

A fee of € 0.10 excl. VAT is charged for each successful transaction.

Activating the integration with Mollie

To activate the integration with Mollie, go through the following steps:

Navigate to settings > integrations > payment services > Mollie
Click on 'connect with Mollie'
You are redirected to the Mollie login page, where you have to log in with your Mollie credentials.
Once you have logged in, the integration is in place.

You have to set up a payment method in Mollie. If you do not, customers get an error message when they try to pay.

Setting up the payment link and QR code

On a sales invoice you can use replacement codes to generate and display a payment link and/or a QR code.

${paymentLink}: you use this replacement code to display a payment link on an invoice.
${paymentQR}: you use this replacement code to display a QR code on the invoice

Payment link

The payment link is a link the customer can use to be redirected to the Mollie payment page. The invoice can be paid that way.
You can add the payment link via:

The invoice remarks: the payment link is displayed at the bottom of the invoice. You use the replacement code via settings > invoices > settings > invoice remark.
The email: the payment link is displayed in the email you send to the customer. You use the replacement code in the invoice email template.
An HTML section of the invoice: the payment link is displayed on the PDF of the invoice. You use the replacement code in an HTML section of an invoice (e.g. the introductory text)

QR code

The QR code is added to the invoice and can only be scanned with the camera of your smartphone. You are redirected to the Mollie payment page. The invoice can be paid that way.
You can add the QR code via:

The email: the QR code is displayed in the email you send to the customer. You use the replacement code in the invoice email template.
An HTML section of the invoice: the QR code is displayed on the PDF of the invoice. You use the replacement code in an HTML section of an invoice (e.g. the introductory text)

Linking payments to an invoice

There is an option to assign a payment to an invoice as soon as the payment has succeeded. To do so, you activate the 'Assign payment link payments to invoices' function. You do this via settings > invoices > settings.
If you have set a 'paid status', the invoice is given this status automatically and a payment is registered on this invoice.
Separately from this function, a remark is displayed on the invoice by default, stating that the payment has succeeded. You will find this remark in Robaws under the 'remarks' tab.
