The firm we wished our clients could hire — so we built it.
Senior Finance Leadership from both sides of the table , channelled into institutional-grade clarity and board-level rigor for ambitious scale-ups across London and the UK.
Good finance stops at a certain size.
As an SME scales past £3m in revenue, its financial demands multiply exponentially. However, most founders are trapped between two unappealing options: relying on a traditional year-end compliance accountant who looks backward, or hiring a full-time CFO before the business can absorb that overhead.
Ruddham eliminates this dilemma. We deliver senior, Big 4 accounting firms-trained Chartered Accountant CFOs on a fractional basis (2 to 8 days per month). You get board-grade pack delivery, 13-week cash forecasting, and transaction readiness at a fraction of the cost.
What We Believe
The uncompromising operating principles that guide every client engagement.
Clean data before clever analysis
Complex 3-statement models built on un-reconciled trial balances are dangerous illusions. We fix core ledgers first.
The person you meet does the work
No pitch-and-switch. Your account is owned and managed directly by Chartered Accountant, Big 4 accounting firms-trained professionals.
Say the uncomfortable thing
If a product line is losing money or a project timeline is unviable, we lay out the cold numbers without corporate spin.
Proportionate, always
We right-size our engagement days to match your company size. Zero unnecessary overhead or bureaucratic bloat.
Radical Fee Transparency
"We never charge markups on software tool recommendations, we do not take hidden referral commissions from banks or ERP vendors, and we never tie clients into long-term lock-in agreements. If our fractional finance leadership doesn't pay for itself in operational efficiency and board clarity, you can cancel at 30 days' notice."
