How do I use Mollie?

After you have registered with Mollie, you can now add an individual paylink to your invoices for your customers.

Please note that it can take around 3-5 working days for your Mollie account to be activated. Only then can you use the paylink function. 

In order to display the Paylink on the invoice, you have to enter the placeholder [Invoice.mollie] when creating your invoice - for example, the Comments field can be used. 

As soon as you have created the invoice, you will find the paylink not only on your invoice, but also on the right-hand side in the invoice detail view. You can copy it at any time and use it in an email, for example. 

You can also provide the payment link to your customers via the customer portal. To do this, you may have to activate the payment in your Billomat account:

  • Navigate to Settings > Administration > Customer Portal.
  • In the Approved Documents and Actions tab, you can click on the box in front of the corresponding option to set that your customers can pay bills and reminders via the customer portal.

How can I let my customers pay with Mollie?

You can now send the link to your customers. You have the option of choosing from the payment options that you have set in Mollie. 

Practical: Since the payment is processed via Mollie, your customers can also pay with payment methods that you do not use yourself.

Note: As soon as your customers have selected the payment method and commissioned the payment, the status in the associated invoice changes to paid so that the invoice is not included in the automatic dunning run. Please note that it may take a few working days for the payment to reach your account.

How can I disconnect from the Mollie add-on? 

To disconnect, simply clicking on the Disconnect button in your Billomat account. This only disconnects the link between Billomat and Mollie - your Mollie account will of course still be available.
