About My Controller
My Controller is an accountancy and tax practice with offices in Windsor and Harrow, supporting businesses across the Thames Valley. The firm describes itself as a modern practice and says it plans to expand its coverage to new locations soon. It was established in 2003, moved into its central Windsor office in 2013, and opened its Maidenhead and Harrow offices in 2016.
The firm offers a range of services for businesses and individuals. For companies, these include bookkeeping, payroll and pensions, VAT, management accounts, year-end accounts, cash flow forecasting and support for start-ups. For individuals and sole traders, it lists Self Assessment, Making Tax Digital and Construction Industry Scheme (CIS) services, along with IR35 advice for contractors. It also offers tax planning, business planning and exit planning as advisory work.
My Controller says it tailors its services to each client's needs, working with businesses from start-ups through to larger enterprises, and uses cloud-based systems where they add value. Its distinctive offer is the Pathway to Profit programme, which sits alongside a Business Academy and all-inclusive monthly packages. The founders, who say they built finance careers before setting up the firm, describe the aim as helping small and medium-sized businesses reach goals that suit them, such as growing profits or achieving a better work-life balance.
Client testimonials on the website praise the team for taking the administrative burden off owners, interpreting financial figures and acting as a trusted part of the team.
