About us 

Hi I’m Sasha Dunn and Numerico is a two partner family business which I started from scratch over 12 years ago now.  Our number one priority is in delivering an excellent service to our clients to maintain our reputation. We are proud of our work, we care for our clients many of who have been with us for many years and recommend us to their friends and colleagues.

For many people, even the word ‘accounting’ makes them yawn it sounds so dull and boring.  But I really love my work. It makes me very happy knowing that I am helping others keep on top of their finances and planning for the future.

So, (with apologies to Monty Python) if you’re looking to charter an accountant to balance your books and give you peace of mind, then get in touch and sail the wide accountancy with Numerico.
