Abacus Jack Team

Based in Durham, with clients across the UK.

Abacus Jack was founded in 2015 by Andy Thomas.  Andy has around 20 years experience in technology, digital payments, finance, accountancy, and consultancy. This combined experience led to a series of questions around why accounting and payments technology was not more accessible to smaller businesses, and why bookkeeping was not simpler and more affordable, particularly for the smallest of businesses. Afterall, all businesses are required to keep business records and pay tax in the same way, regardless of size.

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 50,000 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.
