Clients work directly with an experienced Chartered Accountant. Where a matter requires additional specialist input, Winglets coordinates with a selected network of professional collaborators in the UK and Italy.
We analyse the problem, understand the business behind it, and bring together the right expertise to find a practical solution.

Why Winglets?
In aviation, winglets are aerodynamic devices fitted at the tips of aircraft wings. Their purpose is to reduce drag and improve overall efficiency and performance.
Winglets Business Solution was created around the same principle: focused, well-designed interventions can make a meaningful difference to the efficiency and performance of a business.
Our role is not simply to report the numbers, but to understand what they reveal about the business and where practical improvements may be possible.
Experience and credibility
Winglets Business Solution Ltd was established in London in 2023, building on Vincenzo D'Onofrio's professional career spanning more than two decades in Italy and the United Kingdom.
His core experience is in business planning, financial modelling, budgeting, investment appraisal and business analysis: understanding how a company works, identifying strengths and weaknesses and helping management evaluate practical options for improvement.
He is an ICAEW Chartered Accountant and remains registered with the Ordine dei Dottori Commercialisti e degli Esperti Contabili di Latina. He no longer practises directly in Italy, while continuing to work with selected Italian professional firms on cross-border matters.
Professional standard
Winglets combines an independent boutique approach with the professional standards and ethical framework associated with ICAEW Chartered Accountants.
