Our business was growing and we were aware that we needed not just an Accountant but a company that could provide us with a full professional accountancy service plus all round business advice. John MacMahon & Co. were recommended and that introduction was pivotal to the growth and future success of our business. The input and advice from John McGinn and his team helped us realise what was possible and begin to plan the next steps Without their experience, and expertise we would not have been able to grow our business in the way that we did.
This combined with a very professional and accurate accountancy service enabled us to change the structure of the company which gave us many more opportunities. Alan and Maura McKendry

As a client who has been involved with John MacMahon for almost 30 years I cannot recommend them highly enough. Specifically working with John McGinn and staff who have looked after company accounts, researched and given great business advice in a professional yet friendly manner. If you are a small business, large enterprise or startup - you will find the accounting support you need with John MacMahon & Co

I have been a client of John MacMahon & Co for a number of years and have always found John and his team to be extremely helpful and professional in offering sound advice that has helped me greatly in both running and growing a successful business. The people I was in contact with were always very knowledgeable within their area of expertise, a pleasure to work with and nothing was ever too much trouble. I would have no hesitation in recommending John MacMahon & Co to any prospective business owner that requires a Financial Accountant/Auditor.

John & team at John MacMahon & Co have been invaluable to us during the startup and operation of our business. Their team is polite, professional and approachable and their knowledge of all financial and tax aspects is second to none - all communicated in a way that helps us understand and feel more confident in managing our business.

We spent many years as a client of John McMahon and Co and had two great accountancy technicians during this time which was the reason why we stayed for so long. The company management however overloads its staff with ridiculous workloads meaning that both of the accountants we were assigned to started to drop the ball causing us major problems during critical funding rounds.
We decided to leave when our latest accountant was off on long term sick leave and we couldn't even get a conversation with anyone who could help us leading to issues with unpaid VAT, PAYE and more. This all occurred during a major funding round in the business and was dealt with dishonestly by senior management who made excuses rather than solving the problem.
Senior management also stated on a number of occasions that they would 'work with us' in regards to fees that we felt weren't owed after we had no accountant for nearly 5 months. Instead they sued us for the full balance! If you're a startup company these guys are not for you, they are dangerous to your chances of success. We have moved on to solid provision elsewhere, we would have done years before had our assigned accountants not been so diligent.
If you are an investor taking advice from senior management in this firm that'll be a fantastic way to lose your money! While they market themselves as knowledgable in venture capital and well connected the reality is far away from this claim. If you're a typical small business they're likely okay, but don't believe senior management when they say they're on your side. They're there for the fees and nothing else.
