Accounting Review from Dmitrii Legetskii
This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

Elisa Ramundo’s's Review Sourced from Google
Had an initial consultation with the firm after sending them detailed documentation. While the accountant was professional and courteous during our call, I was later informed they had no capacity for new clients and wouldn't be able to take on work until Spring 2025. This information should have been communicated before scheduling the consultation and requesting documents. While I appreciate their eventual honesty, this approach wasted time for both parties and doesn't reflect well on their business practices. Scheduling consultations when you know you can't take on new clients is not good client service.

Uptown Body Contouring's Review Sourced from Google
Misleading, dishonest and greedy. I was originally told my tax preparation would be£1750. I then received a bill for £2500 for a seven page boiler plate generic memo regarding tax advice -which amounted to a newsletter. After over a year of receiving harassment emails and bills, I paid the £2500 and never use them for tax preparation, for fear of further “advice” and trumped up fees. A good decision on my part to not throw good money after bad. In summary, I paid £2500 just to part ways. I feel like a fool for being ripped off

Holly has been a great help recently both in terms of my business and personal affairs. I am in the process of making some business structure changes in my private dental practice and she has assisted me with all the lengthy paperwork, ensuring that everything is in order. In addition, she has assisted me in researching properties and locations. I would not hesitate in recommending her services as her support has been invaluable to me at this extremely busy time and has allowed me to focus on my patients.Highly recommended +++++

Terri has been an incredible SmartPA assistant for our family over the past 18 months. Her support has been invaluable in managing our busy work and home administrative tasks. Throughout our travels across Europe, the US, and Canada, as well as during our recent move to a new house and country, Terri has been there for us every step of the way. In particular, I have appreciated that Terri has used great judgment in assessing options on all fronts and hasn't just gone for the easy road of blindly following orders. I have trusted her as a "second me" and that has been so helpful. We couldn't have done any of this without her!
