What people say about us

“It was so, so useful!  I did a Payroll Management Diploma last year but your webinar explains things much more clearly.”

“Thank you for a really great day yesterday, I felt that I really learnt a lot and that’s down to the way you [Diane] taught us.”

“COS has been Aquacut Limited’s bookkeeper and trusted advisor for a number of years and have been a vital partner during our exciting journey as we developed our business.

When I bought the business seven years ago, COS were the bookkeepers at that time.  We wished to transition from a one-user, dated accounting system to one based ‘in the Cloud’ and COS were important in advising us of our options and holding our hands during the transition.

Our business is over four times as large as it was seven years ago.  Our company has developed into e-commerce and entered new markets.  COS has been professional advisers, with great feedback and recommendations as well as responding professionally and quickly as we explored together various systems we could adopt.  I’m confident we would have struggled without COS support as they have been there for us, every step of the way.Karen and her team are professional, but user friendly in their approach to business. I cannot recommend them highly enough.”

“I have worked with COS Bookkeeping for over ten years and have always found them to be knowledgeable and efficient. They provide a great deal of support to our mutual clients not only in terms of bookkeeping but also the industry and software knowledge they use to assist clients run their businesses more efficiently.”

“COS Bookkeeping have for many years been a huge support to Allens and our clients. They provide superb service and the quality of the training is top notch. They are consistent, extremely professional and, unsurprisingly, in great demand. I would not hesitate to recommend Karen and her team, and have done many times always with the best outcome for my clients. Karen is passionate about her work as well as being a great communicator with clients on all levels. She deserves her success.”

“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 Diana’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.”
