Jane Atherton


Having joined the audit and accounts team at our parent company Simmons Gainsford in 2009, I became Director of Fl3xiBooks following our launch in early 2017.

My expertise lies in developing and maintaining financial systems and company records and building meaningful and long-lasting relationships with clients.

Grant Gibson


I’ve been at our parent company Simmons Gainsford for the best part of 20 years, working within accounts and audit. I started to get involved in Fl3xiBooks around 5 years ago, where I currently oversee our London team.

My outside interests include football (both watching and managing a team at youth level) but most importantly I love to spend time with friends and family.

Jessica Ridler-Baer


I joined Fl3xiBooks in April 2023 from a firm in London, where I provided outsourced finance functions to E-commerce and tech start-ups.

In my current role I work with clients that need additional insight to their businesses, looking at process improvements and technology implementation to improve overall efficiency.

Claire Simmons

I started at our parent company Simmons Gainsford in 2015, having previously worked in Local Authority, Insurance and Tourism. I moved to the Fl3xiBooks team as an Assistant Manager in August 2019.

When not at work, I spend a lot of my time watching real life crime documentaries ( I am slightly obsessed!)

Tracey Hudson


My day-to-day duties include finding and fixing problems and training and assisting others with bookkeeping and software.

My superpower is being a Grandma and I will always choose cheese over meat!

Joy Carter

Senior Bookkeeper

The part of my job I particularly enjoy is producing Management Accounts.

In my time away from work I am a Cub Scout Leader and find it rewarding to see the youngsters enjoy outdoor activities (even in the rain!)

Paul McNally

I have been working in accounts and finance since 1998, filling various roles before settling into Bookkeeping in 2012.

Outside of work I take a keen interest in most sports particularly Football, F1 and cricket. I am also a qualified cricket umpire and coach.

Megon Wilkinson


Bookkeeping has been a perfect career match for me and I thoroughly enjoy the work!

Kerry Gibb


I take pride in my communication skills and building client relationships is important to me to provide a high quality service.

I joined the Fl3xiBooks team at their London office in January 2022.

In my spare time I enjoy going to the gym, playing football and going out to eat. The most interesting place I’ve visited is Bali.

Heather Maritz


I have worked as a bookkeeper in the UK for the past 3 years. I thoroughly enjoy working with a variety of clients.

My hobbies include reading, woodcarving, cross-stitch and anything new in crafts. I enjoy giving them a bash and see how they turn out!

Mehreen Maqsood


I initially joined Fl3xiBooks as an Apprentice in October 2021, before moving into a full-time position as a Bookkeeper in January 2023.

When I’m not at work I enjoy playing video games, especially competitive FPS games!

Mason Dowle


I started at Fl3xiBooks in July 2022, and I thoroughly enjoy the work. I am also studying for my AAT Level 4 Advance Diploma in Professional Accounting.

Outside of work, my interests include playing rugby for my local team and watching football on the weekends.

Our story so far...


After successfully growing a bookkeeping team within Simmons Gainsford, the decision was made to create a business (Fl3xibooks) within the SG Group. This business would be run by accountants but serviced entirely by bookkeepers, with a focus on providing a bespoke service to clients giving ongoing contact with their dedicated team members.


Three senior bookkeepers and one apprentice are recruited to join our existing team of five.


A new apprentice joins the team. Later on in the year our first apprentice moves to SG to continue their career in accounts and audit.


We hire two more bookkeepers and an assistant manager joins us from SG.


Our third apprentice joins us. Later in the year our second apprentice moves to the SG to continue their career in accounts and audit.


Our fourth apprentice joins us as we decide to double our apprenticeship scheme. We are now a team of thirteen!


Outsourcing manager joins us – this is a newly-created role. We are now a team of fourteen!

Join our team

We pride ourselves on the highly flexible and personal service we provide to our clients, none of which would be possible without the dedication of our wonderful team. If you’re interested in starting or continuing your bookkeeping career with us, we would be delighted to hear from you.
