Established in 2024, Calculo employs 27 staff under the leadership of Jonathan Walton and Rebecca Craker.
Its services include audit and assurance, accounts, tax, payroll, outsourced accounting, and business advisory.
According to a statment, the business specialises in service charge accounting.
The business will operate as Calculo Tax Audit, part of the Shaw Gibbs Group. Existing staff and client relationships will stay central to the firm.
Calculo clients will continue to work with their local contacts while obtaining access to Shaw Gibbs’ corporate finance, specialist tax, and audit resources.
Its employees will join the wider organisation, receiving access to a broader professional network and training programmes.
Craker said: “Our clients value accessible, proactive advice from people who understand their businesses, and preserving that approach was very important to us.
“Joining Shaw Gibbs allows us to continue providing that personal service while giving our clients access to a much wider range of specialist expertise and creating exciting opportunities for our team.”
The deal broadens Shaw Gibbs’ reach across Oxfordshire, Buckinghamshire, and the wider Thames Valley, complementing its existing office in Oxford.
The transaction forms part of Shaw Gibbs’ ongoing geographic expansion across the UK and Ireland.
Shaw Gibbs CEO Peter O’Connell said: “Calculo is a high-quality practice with strong local relationships, an experienced team and an approach to client service that aligns closely with our own.
“Its presence in High Wycombe and Bicester is a natural fit with our Oxford base and strengthens our presence across the Thames Valley. I’m delighted to welcome Jonathan, Rebecca and the whole Calculo team to Shaw Gibbs.”
Last month, Shaw Gibbs acquired White Hart Associates, a professional services firm specialising in the travel industry.
