    "Sharon was a vital part of my business operation for over a decade. She bought so many positives to the business, not least a relaxed and chirpy persona around matters of finance that are so often a dull subject matter. She was extremely diligent in her work and held herself and the finance team to the highest standards. At the same time, she wasn't stuck in her ways. She was constantly looking to improve her offering, add in the latest technology, or take on board ways I wanted to adapt how we managed things. From P&L's, to wages, to bad debts, to customer payments, invoicing and beyond I couldn't recommend Sharon highly enough to SME's who want their finances maintained in a stress free, easy to understand and compliant fashion".

    Mike Cole

    Former CEO Imagine Property Group

  • "We can wholeheartedly recommend Calculus Accountancy Services particularly for small businesses. They are conscientious and thorough in the work and have provided us with all of the essentials for bookkeeping including timely invoicing and follow-up, VAT submissions, as well as providing the necessary information on the company accounts monthly and in time for the end of your reporting".

    Dr Robert M Miller

    Artemida Pharma Limited

  • "Our previous accountant retired and over time we grew increasingly unhappy with the service we were receiving from the company that took over his business. We started looking for a new accountant and Calculus was recommended to us. We met with Sharon to discuss our needs and were impressed by her professionalism and advice to get our accounts back on track. We have now been with Calculus for just over a year and it is the best decision we made. Sharon helped to get our books in order and sort out our VAT registration. Calculus are always quick to respond to any queries we have and submit our VAT and tax returns in a timely manner. We are happy to recommend Calculus Book-Keeping Services".

    Debbie Prizeman

    Martin’s Heating Services

  • "I began using Sharon's services at Calculus Bookkeeping when I first launched my business over 11 years ago and I can say without hesitation that it was one of the best decisions I’ve ever made. From the very beginning, Sharon has handled all of my bookkeeping and payroll with incredible precision and reliability. Thanks to her support, my business has grown steadily—almost doubling in size year on year—and now proudly employs over 20 staff. This kind of growth simply wouldn't have been possible without the confidence and peace of mind that comes from having a first-class financial partner behind the scenes. What sets Sharon apart is not just her technical expertise, but her genuine care for her clients. She takes the pressure off by ensuring every detail is managed correctly and in full compliance with the latest regulations. This has allowed me to focus on running and expanding the business, knowing the financial side is in safe hands. I truly cannot recommend Sharon highly enough. Her professionalism, integrity, and commitment to her clients make Calculus Bookkeeping a vital asset to any business, large or small".

    Peter Barber

    London Waterproofing Solutions

  • "As a business owner, having someone I can trust with the financial heartbeat of the company is absolutely critical. Sharon at Calculus has not only filled that role but elevated it. She blends strategic financial oversight with day-to-day practicalities, ensuring our books are watertight. What truly sets her apart is how tailored and agile her approach is. Sharon understands the pressures of running a business and adapts seamlessly to our needs without ever losing focus on the bigger picture. She is more than just an adviser she and her team have become an integral part of our business journey. I would highly recommend her to any business looking for solid financial support with a personal touch".



    Dagmar Stewart

    MD Imagine Living

  • "I have been associated with Calculus and the team for 8 years now and their services have been invaluable to my business. The provide excellent accounting services and always on hand for any questions or advice. I wouldn't hesitate to recommend them to family and friends. Thanks again Calculus!"
