Testimonial from Amy Kibble

Office Manager at Euan Kellie


“Having had little to no experience in bookkeeping and having learnt on the job there have been many challenging moment, so knowing that the support service at COS is only a phone call / email away has been so reassuring. For me their support has been invaluable.

If I have a query; and I have had many, I have always had a response, if not immediately on the phone, within 24 hours.

Everyone I have had the pleasure of speaking to / communicating with have been very patient and always provide a clear response / solution to my query.”

Testimonial from Jonathan Guy

Managing Director at Aqueous Digital


“We have been using COS for around two years and frankly I don’t know where we would be without them. Mike is a fabulous ‘remote’ member of the team and has been enormously helpful in both sorting our accounting system (and accounts) for us, as well as providing valuable mentoring for our Financial Controller. Highly recommended.”

Testimonial from Abi Wood



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.”

Testimonial from Colette Dalton

Owner of Keeley Consulting


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

Testimonial from Caroline Clarke

Owner of CMC Bookkeeping


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