A new white paper that will be released by Double Diamond Group on Thursday (Oct. 20) argues that the payment facilitator market holds significant potential for independent software vendors looking to generate new revenue.

The big names operating as payment facilitators already have used the PF model to garner a significant chunk of payment processing volume. According to the paper, large companies such as PayPal. Stripe and Square already collectively process hundreds of billions of dollars a year in gross payment volume. This number has the potential to go much higher as other companies enter the market.
