You work directly with a Chartered Accountant with 30+ years' experience — not a junior, not a recruitment placement, and not a rotating team. Engage me as your interim or fractional CFO, Financial Director (FD) or Financial Manager (FM): the person you speak to is the person who does the work, hands-on from day one.

CA(SA) Principal-Led No Hand-Offs Senior & Strategic

What I do

Services

Hands-on financial leadership tailored to the realities of running an SME — engaged for a project, a turnaround, or an ongoing fractional arrangement.

Interim & Fractional CFO

Step-in financial leadership when you need it — covering a gap, supporting a growth phase, or providing the senior oversight a full-time hire can't yet justify.

Business Plans & Capital Raising

Investor-ready business plans and funding strategies, drawing on 30+ years of banking and capital relationships to position your raise for success.

Financial Forecasts & Needs Analysis

Robust models and cash-flow forecasts that show what's coming, quantify your funding needs, and give you the numbers to plan with confidence.

Process Re-engineering & Workflow Automation

I specialise in identifying cost-saving opportunities — redesigning finance processes and automating workflows so your business runs leaner and faster.

Due Diligence — Buying & Selling Businesses and Assets

Independent, rigorous due diligence on acquisitions, disposals and management buy-outs — so you understand exactly what you're buying or selling.

Distressed & Turnaround Advisory

Practical support for businesses under pressure — stabilising cash, restructuring, and finding the path back to a sustainable footing.

About

Larry Sack, CA(SA)

I'm a Chartered Accountant with over 30 years of experience across banking, financial services, startups, privately owned businesses, and distressed opportunities. I founded interimCFO.biz to bring that depth of experience to SMEs who need senior financial firepower without the overhead of a full-time appointment.

My approach is hands-on and practical. Whether you're raising capital, tightening up your forecasts, re-engineering how your finance function works, or weighing up a transaction, I work alongside you to get it done — and to leave your business stronger than I found it.

Frequently Asked Questions

The questions business owners usually ask before getting in touch.

How are engagements structured and billed?

Flexibly — by the day, on a monthly retainer, or for a defined project. You pay only for the time you need, with no long-term employment commitment. We agree the basis up front so there are no surprises.

How much of your time would I get?

That depends on your needs — anything from a few days a month for ongoing oversight, to a more intensive block during a capital raise, transaction, or turnaround. It can scale up or down as things change.

Do you work remotely or on-site?

Both. I'm based in Cape Town and work with clients across South Africa and internationally, combining remote work with on-site time where it adds value.

What size and type of business do you suit best?

Small and medium-sized enterprises that need senior financial leadership but aren't yet at the stage of a full-time CFO — particularly those raising capital, buying or selling a business, or working to get a firmer grip on cash and costs.

Do you provide bookkeeping, payroll or recruitment?

No — and that's deliberate. My focus is senior, strategic CFO work: capital raising, forecasting, due diligence, process re-engineering and turnaround. It keeps the value high and the relationship direct. I'm happy to work alongside your existing bookkeeper or accountant.
