S&W Tech Stack

UK accounting and advisory firm serving mid-market and private clients

Professional Services London, England 1,001–5,000 employees Founded 1881 Privately Held

S&W is a 140+ year-old accounting and advisory practice operating across tax, audit, corporate finance, and restructuring services. Their tech stack is heavily Microsoft-centric (Office, Power Platform, Power BI, Azure) with accounting-specific tools (Xero, Silverfin, Sage 50, QuickBooks), reflecting a traditionally managed professional services operation. Finance-heavy hiring (82 of 117 roles) signals scaling of delivery capacity rather than platform innovation; active projects cluster around M&A tax due diligence, succession planning, and compliance automation, while pain points cite post-merger integration and value realization challenges — typical friction points for a growing advisory firm consolidating client work.
