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.

I highly recommend Cloud Tax Ltd. They are meticulous in their work. They were happy to explain clearly and in non-technical terms the details of my tax return. Also, they are helpful in making other suggestions relating to tax. An absolute pleasure to do business with!

I don’t usually write reviews but every now and then i come across an extremely good service that deserves a mention. Professional, proactive and knowledgeable. Mohit and team went the extra mile and provided more than just the run of the mill services that a lot of accountants provide. I did my due diligence on 2 other accountants at the time and i’m pleased to say that Cloud not only impressed during the initial stages but also on delivery. The other accountants were just an “admin” service. Without sounding arrogant i have enough skills with a calculator and experience of completing online forms to do without them. Mohit and team provide a proper “value added” service with advice to boot.

The folks at the Accountancy Cloud are wonderful to work with. They provide a friendly, personal service. Have given a heads-up on issues before they become problems and always have great communication. What's more, they are perfectly aligned to startup companies. They know the challeneges and go the extra mile by hosting events. Recently I got to attend a startup breakfast they put on at the Shard, where I got to meet some interesting like-minded people. Highly recomended!

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
