Any ideas how I can start to build a stored value platform like PayPal

Hi - I want to put together a stored value solution similar to PayPal. This means that account holders would be able to use various payment systems including credit cards to buy credits on their accounts. These credits would then be used to transfer to online merchants just like PayPal.

I know that Woocommerce plugins can enable the payment methods I need, but is there a widget that will give me a form of stored value account system? And are there ready made solutions for integrating with retailers websites so that money can be transferred from their stored value account to make purchases?

Or am I being too ambitious with Wordpress? :slight_smile:
