I don't know how their service works. Do they pose as a 'gateway company' between you and your customers or are they just a payment gateway? If it's the latter, then the hardest problems still stand since accounting and invoicing is still something that you have to do. It would be great to have a service that resells your goods/services and takes care of all that stuff so you can send a single invoice to them every month and that's it, but frankly, I'm not sure of the legal part of that.
