Having taken the step back in 2017 to set up my own business it has been one that I have been very lucky with.
Modus came into the picture within the last 12 months due to taking over from the previous accountants I was using as they had decided it was time for them to retire.
I was a little nervous at first however from the first conversation with Samantha and the team at Modus I was given a huge boost and relief as their professionalism and methods of business is phenomenal.
The advice and guidance already given to me by Modus has been amazing and one I truly appreciate and will continue to learn from so in my opinion I owe Modus a massive thank you for the work they do.
I would highly recommend Modus to any company as both the work and professional service they deliver is first class.

I have been working with Modus for about 2 years now. I swapped over from an accountant you had made lots of mistakes in my accounts, and Modus put in the time to rectify everything. They are always available to answer questions. We are a small startup and their rates are very reasonable for the quality of work.

Were a business based in Witney and needed urgent help filing our accounts as we were let down by our accountant. Mark and Sam at Modus were very responsive and managed to file our accounts before the deadline. I can highly recommend Modus, many thanks for your help!

We have only recently moved to Modus but cannot rate, Mark, Sam and the whole team highly enough.
Not only are they getting our accounts and admin in order but they are also helping with long term planning and steering the business in the right direction.
A first class team.

Any financial issues that need resolving these are completed in a very professional manner and within expected time frames.

Decided to switch accountant for my IT Limited company to a local company in Oxford area and found Aries Accountants, who are now Modus. They have now been my accountants for both business and self assessment services for over ten years and I have never encountered any issues during this time. All returns have been submitted to HMRC on time and with no issues. I wish to thank Nick and his team for all their help and support since I first stepped into the doors at Aries to now where they have now grown into Modus.
