The Deko payment gateway extension allows you to easily add finance options to your Magento site. Finance calculators are automatically inserted into the product page, cart and checkout and can be added anywhere on the site using the pre-made xml declaration provided in the integration documentation. You are easily able to define the rates available along with the minimum credit amount in Magento's admin panel. You can view a fully working demo at http://dekopay.syncro-it.co.uk
. An Installation service is available if you don't feel confident installing the extension yourself.
