Meet the Team

Meet the husband and wife team behind ClearSum Accounting


Harry and Abi work together to provide clear, calm and reliable accounting support for small businesses.

Harry Whittington

Founder

Harry founded ClearSum Accounting after more than a decade working in finance and accounting roles, including as Finance Director of a £15m turnover pharmaceutical business.


As a CIMA Chartered Accountant, Harry covers all compliance elements of accounting and prides himself on translating complex financial matters into plain English without the jargon.


Outside of work, Harry is a keen traveller with a long-term goal of visiting every continent (yes, even Antarctica!). He also enjoys staying active, whether that is a game of padel or time out on the golf course.

Abi Whittington

Operations Manager

Abi joined the ClearSum Accounting team in December 2025 as Operations Manager, bringing experience from coordination, compliance, resourcing and quality assurance roles.


With a strong eye for detail, Abi enjoys planning and organisation and holds a Lean Six Sigma Green Belt, helping her streamline processes to create better efficiencies at work (and sometimes at home too!).


Outside of ClearSum, Abi enjoys travelling with Harry, discovering new local restaurants, cooking, shopping and getting stuck into a good book. On a sunny day, you will likely find her walking in the park with a coffee and an audiobook.
