My first financial services client used CPA Charge for processing payments. I advised him to open up a Stripe account, however, it's nowhere near as simple for him to do the very things he was already doing with CPA Charge. I wasn't aware that this platforms is very well know amongst the financial service industry. I also found out because of this old request: https://ideas.gohighlevel.com/invoice/p/add-an-affinipay-integration-lawpay-medpay-clientpay-cpa-charge that CPA Charge's parent company has a developer platform for their integration: https://developers.affinipay.com/reference/api.html
