I couldn't recommend these guys highly enough. They have been brilliant from day one. We had a previous accountant who just messed us around and 123 came in and managed to transition everything over and we are now in a much better place. You are able to have lots of contact with them and they are always there to help improve your company. Very hands-on and I feel they do so much more than what is required. If you are looking for accountants, these are your guys!
