Abacus Jack Team

Based in Durham, with clients across the UK.


Abacus Jack was founded 2015 by Andy Thomas.

We are a small team with around 20 years experience in bookkeeping, accountancy, software technology, payment technology, taxation and finance. This combined experience led to a series of questions around why bookkeeping services were not more accessible to smaller businesses, and why services were still so manual, paper based, and expensive.

The concept of Abacus Jack was therefore born out of the frustration with the offerings, costs, and restrictions associated with traditional bookkeeping services and in particular the technology (or lack of) which they use.

Since starting the business we have attracted a diverse range of clients and continue to grow our own team, without compromising on the personal and human nature of our service. We have a 100% record of 5 star reviews, and continue to provide a dedicated service to clients.  

We are regulated by the Information Commissioner's Office and comply with the Data Protection Act.  We are also HMRC agents for Company Formations and Accountancy Service Provision, and have recently become an accredited Free Agent partner. This award winning accountancy software is trusted by over 65,000 UK businesses and all our clients have access to their own Abacus Jack Free Agent account, together with our unlmited help and support.

"We aim to make our customers lives better by removing the worry, uncertainly, and burden of bookkeeping and taxation.

What's important to us...

We want you to love working with us, and love contacting us. That's why we uphold the following values:

Honesty - We will always act with honesty and integrity in everything we do for you.

Clarity - We will always be clear about our costs, services, and what you can expect from us.

Energy  - We love what we do and we want this to be reflected in how we deal with our clients. Bookkeeping is fun - right?

Approachable - there is no such thing as a silly question. If you need to ask us something - ask. Running a business can be daunting. We genuinely want to to make your business work and that's why all our client packages place no restriction on how much support we offer.

How to get in contact

We love to hear from new and existing customers. Email, call or arrange to meet us. Just because we operate a digital service, it doesn't mean there isn't a human at the end of the phone, or available to meet.
