We have now released modules for Prestashop, Magento, Oscommerce and Zencart that are supporting both Klarna invoice and Klarna Account in the Netherlands and Germany. As usual
you will find the modules at our integration guide

NOTE! Both our Zencart and OsCommerce module has been changed so the invoice fee are now entered in the modules inc. VAT instead of excl. VAT. Remember to change your invoice fee accordingly.

If you encounter any bugs, please let us know as soon as possible.
