When should a UK D2C brand first consider a fractional CFO?

The signal is rarely revenue alone. It is usually the first time a decision — a fundraise, a debt facility, a channel expansion, a contribution margin problem — feels too big to take with just the founder and the accountant in the room.

For a UK D2C brand the typical range is £3,500 to £7,500 per month. Below that you are buying part-time hours, not strategic capacity. Above that you are paying for active fundraise or exit work.

What does the first 90 days look like?

Month one: full diagnostic and contribution margin rebuild. Month two: integrated three-year model and cash forecast. Month three: a first quarterly board pack, the next-quarter operating plan, and the two or three decisions that should come out of the work.

How do I avoid hiring the wrong CFO?

Ask for two named consumer brand references, ask which stack they have worked in, and ask for a sample of the monthly pack they would produce. Generalist FDs are usually exposed quickly by these three questions.

Retainer for ongoing finance leadership; project for fundraise or exit readiness. Mixing them on a single engagement usually leaves both jobs half-done.

A one-month rolling notice period is the standard. Lock-ins are a red flag.

The UK D2C Founder's Guide to Hiring a Fractional CFO

A practical guide for UK D2C founders on when to hire a fractional CFO, what to look for, what to pay, and how to make the first 90 days produce real outputs.

The signal to hire

The most common pattern is this: a founder is making excellent operational decisions on instinct, has a clean accountant, and the brand is growing. Then a decision arrives that does not yield to instinct. A SEIS round needs an integrated three-year model. A retailer listing needs cash modelling. A second paid channel is underperforming and no one is sure whether to scale it, cut it, or fix the attribution first. At this point a fractional CFO stops being a nice-to-have and starts being the cheapest way to make the next ten decisions well.

The cost of being wrong on a single one of those decisions usually exceeds twelve months of CFO retainer. That is the unit economics of the hire.

What good scope looks like

A monthly close review and founder-readable board pack
Contribution margin maintained by channel and by SKU
An integrated three-year model the founder can edit
A 13-week rolling cash forecast
An inventory financing strategy with the actual facilities modelled
Quarterly review of the operating plan against actuals
Direct involvement in any fundraise, debt, or exit conversation

What this is not: bookkeeping, VAT, year-end accounts, or transactional finance work. Those belong with a specialist ecommerce accountant.

What good cadence looks like

Two to six days a month, depending on phase. A baseline of one monthly close session, one decision-making session, and ad-hoc availability is roughly two days a month. During a fundraise or working capital crunch, weekly contact and a four-to-six-days-a-month cadence is the typical step up. The retainer should reflect the cadence, not the revenue.

Pricing in the UK D2C market

For a consumer-brand fractional CFO with the right specialist background, the market price in the UK is broadly:

£3,500

Lower end of the UK consumer-brand fractional CFO market for ongoing engagement. Below this you are usually buying part-time hours, not strategic capacity.

£7,500

Mid-market for an active engagement with weekly cadence.

£18k–£35k

Fixed-fee project pricing for fundraise readiness, depending on round size and historical state.

The first 90 days

A good fractional CFO produces a complete contribution margin rebuild and a cash forecast in the first month, an integrated three-year model in the second, and a board-ready pack plus operating plan in the third. By day 90 the founder should have a sharper view of which channel funds which channel, which SKUs to scale, and which decision is up next. If by day 90 the output is only a tidier monthly pack, the hire was not the right one.

Questions to ask in the intro call

Which consumer brands have you worked with at our revenue range? Can I speak to two of them?
What stack do you typically work in, and what would you do with mine?
What does month one produce, concretely?
What is your notice period and your fee structure?
What types of engagement do you refuse, and why?
If we were to need a fundraise in six months, how would that change the engagement?

Red flags

A multi-month lock-in
A commission on capital raised
No named consumer-brand references
An unclear scope ("whatever you need") and an unclear price
Subcontracting the work to junior staff
