"Growth, Success, and Expert Guidance"

"Jonathan has looked after me since the late 1990’s when I first established my own company, and has been instrumental in helping me grow, advising me all the way through the company’s lifecycle to include becoming a £35m company and my recent exit from the company involving a Company Purchase of Own Shares. Jonathan has always looked after my personal taxes throughout too."

"10 Years of Trusted Tax & Audit Support"

"We have been using Rebecca and Jonathan for nearly a decade as auditors, accountants and tax advisers including complex Capital Allowances computations. We are a subsidiary of an overseas global company and Calculo have had considerable interaction with our parent company auditors for many years. Calculo have also given me proactive personal tax advice and assisted me in my share disposal to include valuations and maximising my family tax position. They have always been very helpful and the advice given over the years has proven to be 100%."

"Timely & Trusted Financial Reporting for AIM Compliance"

"We have worked with Vikki Marzana and the team for our outsourced accounting and payroll provider since we first listed on AIM in 2017. Vikki Marzana has been our primary point of contact throughout that time and has consistently provided us with an excellent service. She is always available for questions and produces our monthly management accounts promptly and reliably. She is always of great assistance in our annual audit process, both during the planning and systems review pre year end and the post year end audit field work. This has enabled us to publish our annual accounts within 2 to 3 months of year end. As a public company, this is invaluable for investor confidence."

"Professional, High-Standard Audits – Every Time"

"Jonathan and the team had been recommended to me by a local law firm as we had been looking for new accountants to conduct our annual Audits. From initial contact both Rebecca and Jonathan have been verry helpful and professional throughout. The team at Calculo completed our audits rapidly and to the highest standards on time every time. We look forward to many more years working together for our audits and financial advice."

"More Than an Accountant – A True Partner"

We've been working with Vikki at Calculo for some time now, and the support she has provided has been truly outstanding. She has consistently gone above and beyond to help us with our general and annual accounts, ensuring everything is accurate, timely, and stress-free.

Vikki also manages our payroll with great efficiency and attention to detail, giving us complete confidence that everything is handled correctly each month. Most notably, she has been instrumental in guiding us through the complex process of selling our company. Her expertise, responsiveness, and clear communication have made a huge difference during what could have been a very stressful time.

We can’t thank her enough for her professionalism and the high level of service she delivers. Highly recommended!
