    Fantastic Customer Care

  • Pinnacle have been my accountants for 2 years and I am very pleased with their 1 to 1 attention. If I have any problems or queries, they are quick to get back to me to resolve any worries or issues I may have. I am not an accountant and the team are great at explaining some of the terminology in plain English! Pinnacle make accounts, tax returns and VAT very easy and not a worry so I can get on with the work in hand. Thanks so much Pinnacle.

    One to One Attention

  • 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!
