  • I rate Pinnacle very highly.  My experience with them has been that they can provide our book-keeping and statutory requirements at a reasonable cost, but also have the back up of specialist accountants and advisors when necessary. Pinnacle have been pro-active in pointing out ways in which we can be more efficient with our financial affairs resulting in significant benefits. All in all an excellent service and one which I would highly recommend!

  • We are very happy with the services we have received from Roger and the team. They were instrumental in selecting, establishing and training our staff in the online accounting software Xero, which is user friendly, easy to navigate and we can access our accounting records anywhere on the globe, as long as we have internet access. We appreciate their pro-active approach to identifying the best solutions to maximize out tax liabilities and are always very willing to assist when we need solutions. In short they provide a great service and always make you feel welcome, we look forward to continuing with their services in years to come.
