Fractional CFO for D2C and Shopify Brands

Fractional CFO services for UK D2C and Shopify brands. Channel-level unit economics, cash runway, inventory financing, and a board pack written for founders.

The job a D2C fractional CFO actually does

A UK D2C brand has three financial problems and they are all entangled. The first is contribution margin: how much does an order actually make once you have paid for product, returns, fulfilment, payment processing, the right share of paid acquisition, and the long tail of platform fees nobody tracks. The second is cash: how much of the business is locked in stock, in transit, in supplier prepayments, and in the gap between paying for inventory and collecting from the customer. The third is growth: where the next £1 of marketing should go, and which channel is quietly subsidising another.

A fractional CFO owns these three problems. Day to day that means a clean monthly close, an integrated three-year model, a weekly cash view, contribution margin tracked by channel and by SKU, and a founder-readable board pack. Decisions in the room rather than reports in your inbox.

What is in scope

  • Monthly close oversight. We review your accountant or bookkeeper's work, push back on anything that does not reconcile, and own the numbers that go to the board.
  • Contribution margin rebuild. Channel, SKU, and customer cohort. From Shopify, the payment processor, A2X, the 3PL invoice, the returns log, and the ad platforms.
  • Cash runway and 13-week cash forecast. A model the founder can edit themselves, with sensitivity around stock arrivals and ad spend.
  • Inventory financing strategy. Outright purchase, supplier terms, asset-based lending, revenue-based finance, or invoice finance — modelled against the cash position.
  • Pricing and promotion. Modelling promotional mechanics against true contribution margin before commitment.
  • Board pack and investor reporting. Monthly. Written for the founder, useful for the board.
  • Fundraise and exit readiness. Engaged separately when the moment arrives.

The tools we work in

We integrate into your existing stack. The typical Oro client runs Xero or QuickBooks for accounting, A2X for sales-channel reconciliation, Shopify with native or Triple Whale / Northbeam / Lifetimely for attribution, Klaviyo for email and SMS revenue, Cin7, Unleashed, or Inventory Planner for stock, and a 3PL or in-house fulfilment provider with monthly invoicing. We do not require you to switch stack. We do require clean data going in.

Cadence and price

Retainers run from £3,500 to £7,500 per month for ongoing fractional CFO work. The driver is the rhythm of the engagement, not your revenue line. A monthly close, a quarterly board, and a single decision-making session a month is the low end. A weekly cash call, an active fundraise, a rebuild of contribution margin, and twice-monthly decision sessions is the high end. We propose a number on day one and we hold to it.

When this is not the right service

If the question is bookkeeping accuracy, VAT, or year-end accounts, you need a good ecommerce accountant. We are happy to recommend two or three we work alongside frequently. If you are above roughly £20m of revenue, raising consistently, or running a complex group structure, you should be hiring a full-time CFO. We can scope the search and the role definition for you and hand over cleanly.

Frequently asked questions

How much does a fractional CFO for a Shopify brand cost in the UK?
For most UK D2C brands between £1m and £15m of revenue, a fractional CFO retainer sits between £3,500 and £7,500 per month. The driver is cadence and scope, not turnover. A monthly close plus a quarterly board is at the lower end; weekly engagement during a fundraise or working capital crunch is at the higher end.
When does a Shopify brand need a fractional CFO rather than an ecommerce accountant?
An ecommerce accountant produces accurate numbers. A fractional CFO interprets them and makes decisions with the founder: should we add a third paid channel, raise debt against inventory, drop the bottom 30 percent of SKUs, change the subscription cadence. If the question is "what should we do next", an accountant is not the right tool.
What tools do you work in?
Xero or QuickBooks for accounting; A2X for ecommerce reconciliation; Shopify analytics; Triple Whale, Northbeam, or Lifetimely for attribution; Klaviyo for revenue-by-flow; Cin7, Unleashed, or Inventory Planner for stock; Google Sheets and Excel for the integrated model. We do not require you to switch stack.
How is this different from a full-time CFO?
A full-time CFO costs £140k to £200k all-in for a UK consumer brand and is justified above roughly £20m revenue or during a sustained fundraise cycle. Below that, a fractional CFO gives you the same decision-making capacity at a fraction of the cost, with the same person on the line through the year.
Do you handle bookkeeping or VAT returns?
No. Oro is a CFO function, not a finance department. We work alongside your bookkeeper or accountant. If you do not have one, we will recommend two or three firms that we know work well with consumer brands.
What does the first month look like?
Week one: data access and a top-to-bottom financial diagnostic. Week two: rebuild contribution margin by SKU and channel from raw data. Week three: cash runway and inventory cycle model. Week four: a first monthly pack and the three decisions you should make this quarter.
Can you help us raise SEIS or EIS investment?
Yes. Fundraise readiness is a separate engagement, but for an existing retainer client we will absorb the early diligence work and only scope a fundraise sprint if and when it is needed. See the fundraise-readiness service for detail.
