Ecommerce is the industry where the P&L lies most convincingly. A DTC brand can post $4M revenue at a "healthy" 60 per cent gross margin on paper and still be losing money on every second order once shipping, payment fees, returns, and customer acquisition cost land where they belong. It is also the industry where growth eats cash fastest: every 30 per cent revenue jump demands inventory paid for months before customers pay you. A fractional CFO exists to make both problems visible, at $2,500 to $7,000 a month.

A unit economics model per SKU and per channel. Contribution margin after all variable costs, refreshed monthly. This one artefact typically changes the product roadmap: SKUs get killed, bundles get repriced, free-shipping thresholds move.
A 13-week cashflow forecast tied to the inventory calendar. Purchase orders, deposit schedules, container timing, and promotional peaks (a Black Friday inventory build is often the year's largest cash event) mapped against receipts. Run a first pass with the cash flow forecast calculator.
Ad spend governance. A blended CAC ceiling derived from contribution margin and target payback (commonly 60-90 days for consumables, up to 12 months for high-LTV categories), enforced weekly.
Inventory discipline. Weeks-of-cover targets by SKU, aged stock flushing rules, and reorder points that reflect cash reality, not just sales velocity.
Margin benchmarking. Australian DTC brands typically operate in a 38-42 per cent gross margin band after landed costs at the mid-market; knowing where you sit against industry profit margin benchmarks tells you whether the fix is pricing, sourcing, or volume.
Funding readiness. Inventory finance, revenue-based funding, and bank facilities all price off reporting quality. Clean monthly management accounts and a defensible forecast cut the cost of growth capital.
A $5M-revenue Australian DTC brand, 9 staff, Shopify plus Amazon, offshore manufacturing on 30 per cent deposits. Reported gross margin: 58 per cent. Reality after a fractional CFO rebuilt unit economics: blended contribution margin of 31 per cent, with one product family at 9 per cent contribution consuming 40 per cent of ad spend.
Actions over two quarters at $4,500 a month: repriced the weak family (+8 per cent), lifted the free-shipping threshold from $75 to $100 (average order value up 12 per cent), imposed a $38 blended CAC ceiling (spend cut 18 per cent with revenue down only 4 per cent), and restructured supplier deposits from 30/70 to 20/40/40 against a 13-week forecast. Net effect: EBITDA swing of roughly $310,000 annualised against $54,000 of CFO cost, and the December inventory build funded without the founder's credit card.
From roughly $2M revenue, or earlier if inventory-funded growth is straining cash, ad spend exceeds $30,000 a month without a payback rule, or a raise or exit is on a 12-18 month horizon. If the books themselves lag (settlement statements unreconciled, inventory not on the balance sheet), fix the record first via a provider that runs the bookkeeping layer and the CFO layer together; the alternative is strategy built on fiction.

Ecommerce engagements typically run $2,500 to $7,000 per month depending on channel count and inventory complexity, versus $250,000-plus all-in for a full-time hire (priced honestly in our full-time CFO cost guide). Size the payback for your revenue with the fractional CFO ROI calculator.
What does a fractional CFO cost for an ecommerce business in Australia?Typically $2,500 to $7,000 per month, scaling with SKU count, channels, and inventory complexity. Project engagements (a raise model, a unit economics rebuild) run $5,000 to $25,000.
What gross margin should an Australian DTC brand target?
Mid-market Australian DTC brands commonly land in a 38-42 per cent range after landed costs, with premium categories higher. The more decision-useful number is contribution margin per order after all variable costs.
How is ecommerce cashflow different from other industries?
Cash goes out for inventory and advertising long before revenue arrives, so growth consumes cash even when the P&L shows profit. The cash conversion cycle, not the profit line, determines survival during scaling.
What is a healthy CAC payback period?
Commonly 60-90 days for repeat-purchase categories and up to 12 months where lifetime value is high and proven by cohort data. If payback is unknown, that absence is itself the finding.
Can a fractional CFO help with inventory finance or a raise?
Yes. Building the model lenders and investors will test, cleaning the historicals, and running due diligence are core fractional CFO work, and they materially affect pricing of capital.
Do I still need a bookkeeper if I engage a CFO?
Yes. Settlement reconciliation, inventory accounting, and GST across channels are bookkeeping work; the CFO layer depends on it being current. Combined providers remove the coordination gap.
