A fresh approach to bookkeeping and accountancy

Abacus Jack is about service, ethics and technology.

We take the time to get to know you and your business. This means understanding what your business does, how you prefer to operate, and what you expect from a bookkeeper and accountant.

We will provide you with dedicated support, guidance, and the technology to run your business finances in complete compliance with UK tax law.

Whether it is setting you up to take card payments from your customers, to running your payroll or preparing tax returns and accounts, as HMRC agents for Accountancy Service Provision, we can help with all aspects of your business finances.

Abacus Jack founder, Andy Thomas, has over 20 years experience in business finances and will be your dedicated point of contact. We recognise that every business is different. We help contractors, sole traders, partnerships, and other small businesses. Whether you are looking a few hours support each month, or the complete management of your business finances, we can help you.

Our Technology

Business finances are becoming digital. As a business owner, that means allowing customers to pay you digitally, keeping electronic records, providing regular submissions of data to HMRC, and being able to accurately forecast your tax or cashflow.

This level of record keeping requires simple, effective and reliable software.

We can provide FreeAgent software to all our clients, at no extra cost. It is used by 65,000 UK businesses, and has won ‘Best Small Business Accounting Software 2018’.

We can also provide or work with other accountancy software. Please ask for further details.
