It has been my pleasure to have known Karen, Diane and the COS team for nearly ten years now. We first met due to my work with The Federation of Small Businesses and COS have been an important supporter of the organisation.

In all my dealings with COS I have found them to be highly professional and diligent throughout. Furthermore, they have positioned themselves as an integral part of the business community in the Manchester area due to Karen and Diane’s ever-present high profile.I would also go on to say that as a company they are very well respected by the Manchester businesses as bookkeepers and experts in their field.
