High Level should create their own payment gateway that is native to the software both for for-profit and non-profit organizations. Within this system there is a reasonable base percentage fee that can be added on to. This is a similar concept to High Level creating LC phone and email with rebilling capabilities. For Profit capabilities should add on CC/ACH fees into taxes. For Non-Profits this should come with the ability for customers of SAAS clients to choose ability to add on CC/ACH fees to the Donations/choose your own price or to leave it off so the SAAS client pays that fee. High level users should be able customize, white-label, and resell this payment gateway as stand alone SAAS function or as an integrated capability within their SAAS offer.
