You lead the business.
I’ll lead the finance.

Fractional Head of Finance for SMEs who have outgrown their bookkeeper but aren’t ready for a full-time CFO. I take full ownership of your finance operations so you can focus on scale.

I help founder-led businesses (£1m–£20m turnover) find exactly where their margin is leaking and how to protect their cash — in days, not months.

Reach out when the numbers don’t feel right:

The Paper Gap: Your P&L shows profit, but your bank account feels tight.

The Tax Surprise: VAT or Corporation Tax deadlines feel like an emergency every time.

The Scaling Trap: You’re winning more work, but the cash pressure is increasing.

The “Accountant” Silence: Your accountant says “it’s normal”, but you know your business shouldn’t feel this heavy.

The Safe Exit: You’re unsure how much you can actually take out of the business today without risking next month.

If even one of these feels familiar, a short conversation is usually enough to regain clarity.

Who ISM works with

ISM is a good fit if you:

  • run a founder-led business (£1m–£20m turnover)
  • already have an accountant, but still feel uncertain
  • notice cash feels tighter despite “okay” reports
  • are making decisions with more risk than before


ISM is a good fit if you:

  • early-stage startups
  • bookkeeping or compliance support
  • businesses looking for tax advice or filings

ISM does not provide regulated accounting, tax or investment advice.

What you get from ISM

ISM provides

  • independent financial judgement
  • calm cashflow sense-checking
  • decision support when timing, risk, and costs collide

ISM does not

  • bookkeeping or transactional finance
  • VAT, accounts filing or tax advice
  • replacing your accountant

When the reports exist, but the clarity doesn’t.

You’ve built a successful business, but the financial weight is starting to feel heavier. Reach out if:

  • The Paper Gap: Your P&L shows profit, but your bank account is empty.
  • The Tax Surprise: VAT or Corporation Tax deadlines feel like a recurring emergency.
  • The Scaling Trap: You’re winning more work, but the cash pressure is only increasing.
  • The “Accountant” Silence: Your accountant says “it’s normal,” but you know your business shouldn’t feel this fragile.
  • The Safe Exit: You aren’t sure exactly how much you can safely take out today without risking next month.Calm, independent financial judgement — not tied to selling services

How it works

ISM engagements are focused and advisory in nature.
We typically begin with a one-off diagnostic conversation designed to clarify what matters most next.

You’ll leave with clarity, priorities, and a calm plan — not more spreadsheets.

There is no obligation to continue beyond the initial conversation.

Start a conversation

Good financial decisions rarely come from more data. They come from understanding what deserves attention, what can safely wait, and when to slow down before committing.
