I don't have to handle VATMOSS (yet), but here is a list of providers/libraries that I found most interesting for my use cases: https://pinboard.in/u:rsto/t:vatmoss https://pinboard.in/u:rsto/t:vatmoss I don't expect to make enough money with my side business that a 3rd party provider would be affordable, at least not one with a fixed rate.
