They handle paying vat and sales tax for you. Your customers purchase from them. You make a single b2b invoice to paddle. That said their API is very basic and their UX is not on par with what you can. A lot of operations are not possible (eg. Letting users change their billing details, such as company or personal, vat number, etc) They also won't migrate your credit card data if you're too small. www.getrevin.com looks like a much better alternative: they basically create a stripe account and add you to it. You integrate with your their stripe account and they pay you, same as paddle.
