Helping small businesses in Oxfordshire and Berkshire


We are a team of chartered certified accountants who specialise in providing financial support to small businesses, start-ups and private individuals. We’re located near Abingdon and work with clients throughout Oxfordshire and Berkshire. We provide a caring, friendly, yet professional, service that puts the best interests of our clients first.


Inca was founded after Lesley and Graham Carson both experienced ‘issues’ as clients of other accountancy practices.

(Graham ran a £60 million turnover business supplying SIM cards to the mobile phone industry while Lesley ran the finances in Europe for a leading Customer Relationship Management systems provider, listed on the US NASDAQ exchange.)


From the outset Inca’s focus was to help and support small businesses. To make that happen, the company ethos is to build open, honest and long-term relationships with clients, based on a genuine desire to help.

Every year we set aside 5% of our profits for local charities and good causes.

The Inca team gets together and selects four local charities that are important to them. Each of those charities receive 1% with the remaining 1% kept aside for any ad-hoc causes the team wish to support. Since 2012, our donations have totalled just under £23,000, and our goal is to donate a further £50,000 over the next five years.

Saving lives

As part of the B1G1 global scheme, every time we’re referred to an individual or business that goes on to become a client, we say thank you by purchasing a mosquito net for a child in Kenya.

Since 2013 we have already purchased 143 nets and in 2016 we decided we wanted to help even more children and now we purchase a net for every single new client joining our community.

Malaria is the biggest killer of children under 5 years of age in Kenya. By 2020 with your support we will have helped save the lives of over 700 children.

“I have run a business for 5 years and have been disappointed with other accountants in the past: many like to bill you for every query, while making you feel like a second-class citizen as a small business. It was a breath of fresh air to discover Inca – Graham and the team provide an excellent personal service, and have always been happy to answer phone and email queries at no extra cost. Highly recommended.”
