Xero Bridge by Parex

This was actually set up by my colleague who has a lot of knowledge regarding system integration so can't speak as to how easy/hard it was to put in place, however, since it has been set up it has been running perfectly well. I recently had to contact their software support team, as i thought i had changed a setting which would cause problems, and was pleasantly surprised that i was contacted within a couple of hours. Kumar emailed me and took me through the situation step by step which was very helpful. Would recommend.
