Yes you can! You can send the customer a payment link by e-mail. This can be done in 2 different ways.
1. You create a payment button and mail the URL link to the customer by e-mail.
See the article 'How do I create a payment button'.
2. You send the customer an invoice + payment link.
The customer receives an invoice as an attachment and an iDEAL payment link in the e-mail.
See the article about the module 'Invoicing'.
