Is it possible to process credit cards and have the payments go to another company's merchant account? For example, let's say that you add 5 donate buttons on your website, with proceeds going to 5 different charities. Rather than creating a trust fund to hold the money going into your account so that you can disburse the funds (and not be taxed as income), I'm wondering if you can simply add processing code such that each button has funds going to different merchant accounts (none of which are yours!). I've asked paypal if they support this, and they don't. But I am having a hard time figuring out if credit card merchant accounts allow this.
PayPal Adaptive Payments supports this scenario. Adaptive Payments is an API, and would require some processing code to implement. It's more complicated than their existing Donate buttons (copy/paste some HTML).
