Cover Letter

Dear Hiring Manager, I am writing to express my interest in opportunities within Business Development, Account Management or Commercial Sales. With more than 20 years of experience across B2B sales, commercial development and client relationship management, I have built a strong track record of generating new business, developing long-term customer relationships and consistently exceeding revenue targets. Throughout my career I have worked across several sectors including large format print, manufacturing, commercial services, construction and specialist consultancy. Most recently, my experience has been within specialist tax consultancy businesses focusing on areas such as R&D tax credits and embedded capital allowances. These roles provided excellent commercial experience and also gave me the opportunity to step into leadership and management responsibilities. While I valued the opportunity to develop those skills and challenge myself professionally, it also reinforced where I deliver my strongest results - within front-end business development, relationship management and winning new business opportunities. I have always been most successful when focused on building commercial relationships, identifying opportunities, developing pipelines and driving revenue growth directly. This was particularly evident during my long-term success with William Smith Group, where I developed accounts significantly and secured major commercial contracts. I am now looking for a long-term opportunity where I can continue to utilise my strengths in business development and customer relationship management, while contributing positively to a commercially focused and growth-oriented business. I believe my experience, resilience, commercial awareness and ability to build strong client relationships would allow me to make a positive contribution to your organisation. Thank you for taking the time to consider my application. I would welcome the opportunity to discuss how my experience and approach could support your business. Yours sincerely, Gwydron Siswick
