Sayer Vincent

What Sayer Vincent does

Sayer Vincent is a London-headquartered limited liability partnership (LLP) providing audit, assurance, tax advisory, and consulting services exclusively to charities and social purpose organisations in the United Kingdom. Founded circa 1992 and registered in England and Wales under company number OC390403, the firm employs 101-250 people and addresses sector-specific compliance requirements including the Statement of Recommended Practice (SORP), Charity Commission guidance, Gift Aid, VAT, grants and contracts, and reserves policy development. Its service portfolio spans six core lines: external audit, USAID and grant audits, tax advisory and compliance, mergers and due diligence, internal audit and risk, and training and facilitation.

The firm operates as a partner-owned LLP with no parent company, private equity backing, or external institutional investment disclosed. Revenue is generated through professional service fees for engagements across the six service lines, targeted at a single UK vertical (charities and social purpose organisations). Its go-to-market is built on direct outreach, referrals, sector events, and a content-driven marketing approach comprising an extensive free resource library (guides on auditing, financial management, VAT, Gift Aid, governance, reserves, and SORP), a monthly newsletter, regular webinars, and the annual Charity Accountants' Conference delivered in partnership with the Directory of Social Change. Distribution is single-country (United Kingdom), and the delivery model is human-capital-intensive: named partners and senior managers author content, host training, lecture at Bayes Business School, and lead client engagements. No proprietary technology platforms, software products, or AI/ML capabilities are disclosed.
