What people say about us

The webinar hosted by Karen was, as always, very informative and whilst Karen presents in a very friendly manner she is extremely professional and knowledgeable. I wouldn’t hesitate to recommend COS.”

Having used Xero and Sage for many years, I’ve just taken on a client who wants to use Quickbooks. As this was my first client on the platform rather than stumble my way around, I decided to get some help with the navigation of it. As always Karen was happy to help and to share her in-depth knowledge and expertise with me. After just an hours meeting my confidence with the new platform rocketed. COS have a way of making their members feel part of a wider support/mentoring network, which in my opinion makes being self-employed less daunting and isolating. Thank you so much

“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.”
