I have been working with Artifin Accountants for many years and I am extremely satisfied with their service. They are professional, reliable and always available to answer questions or provide clear advice.
What I value most is their attention to detail and their ability to explain complex tax and financial matters in a simple and practical way. They have helped me manage my accounts efficiently and with complete peace of mind.
I would highly recommend them to anyone looking for a trustworthy and knowledgeable accountant.
Special thanks to Mr Rahim!

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

We are a cattle feed manufacturer based in Sangli, and BSMART has been a valuable consulting partner for us. Their team helped us with entity structuring, inventory control, production process accountability, and financial process strengthening.
They understood our manufacturing business well and gave practical, actionable guidance to improve systems, reporting, and decision-making. We would highly recommend BSMART to SMEs and manufacturing businesses looking for a reliable partner for all kinds of business consulting, financial consulting, and process improvement support.

Over the years, I’ve had the chance to see how BSMART operates, and what stands out is the clarity and intent they bring to their work. The team comes across as highly professional financial consultants with deep expertise in fundraising. What I appreciate most is their client centric mindset. The solutions feel thoroughly thought through and tailored to each situation.
Overall, their approach feels practical and well rounded. I would definitely recommend them to anyone looking for structured and reliable financial guidance.
