Growing past $10M: the structure has to change first
Updated: Sep 28
More revenue on the same setup means more risk, not more profit. Past $10M turnover, the structure that got a builder here starts working against them: assets sitting exposed in the trading entity, a tax position built for a business half this size, and reporting that can't say which of seven live jobs is actually bleeding. Restructure before you scale — entities, tax position, and the monthly numbers that let you take the right next project instead of just the next available one.
What actually breaks when a builder scales past $10M?
Three things move at once, and they compound each other.
Risk concentration. Plant, vehicles, cash reserves and sometimes property sit in the same entity that signs the building contracts. Below $10M the exposure is real but survivable. Above it, a single disputed variation, a defect claim or a head contractor going under can be large enough to put those assets in the firing line at the same time the business needs them most.
Working capital. Every project front-loads cost and back-loads receipts. At $6M turnover on two or three jobs, an owner can fund that gap from retained earnings and a bit of headroom on the overdraft. At $12–15M on five or six concurrent jobs, the gap is proportionally the same size but the dollars are not — and the facility that comfortably covered the smaller business is now the ceiling on how much work can be taken on.
Reporting. A blended, business-wide P&L was good enough to run three jobs by feel. It cannot tell an owner which of seven concurrent jobs is losing money, because the other six are quietly paying for it. That is not a reporting inconvenience — it is the mechanism by which a growing builder's best revenue year becomes its worst margin year.
Why does growing revenue make cash flow worse, not better?
Because growth doesn't remove the funding gap between cost and claim — it multiplies it. A builder moving from $10M to $15M isn't just doing more of the same work; they're usually running one or two more concurrent jobs, each starting its own cost-ahead-of-claim cycle before the last one has fully unwound.
This is why builders commonly hit their tightest cash position in their best growth year on paper. The profit is real and will land — eventually, as retentions release and final claims are paid. In the meantime, the business is funding a bigger gap with the same overdraft limit and the same equity base it had at $10M. Overdraft facilities in the $150,000–$400,000 range are common for builders in this turnover band, and it's not unusual for a fast-growing $12M builder to be running that facility at 80–90% utilisation through the middle of a big job — well before the bank statement shows any sign of a problem.
Should you separate assets from the trading entity?
For most builders past $10M, yes — but the specific structure (a separate asset-holding entity, a trust, how plant and vehicles are leased back to the trading entity) depends on contract types, licensing requirements, home-warranty insurance eligibility and the existing tax position. That's a question for specific advice, not a general rule, because getting it wrong can create its own tax and licensing problems.
What is general: restructuring is materially cheaper and cleaner done ahead of a growth phase than during or after one. Moving assets or splitting entities once a business is trading hard, carrying live contracts and mid-project, usually means higher stamp duty and CGT exposure, more complex creditor and surety consents, and a harder conversation with the bank about security. Builders who restructure reactively — after a dispute or a bad year has already shown the exposure — routinely pay several times what a planned restructure at $8–10M turnover would have cost.
What tax and ownership questions come up at this size?
A few show up in almost every builder past $10M, and none of them have a one-size answer:
Whether trading through a company, a trust, or a combination still matches how profit is actually being distributed and reinvested.
Whether the entity structure still supports the licensing and surety/bonding position the business needs for larger contracts.
Whether related-party arrangements (asset leasing, management fees, family employment) are documented well enough to survive scrutiny at this size.
Whether the tax position was set up for a $4–5M business and has simply never been revisited.
None of this is a DIY exercise, and it isn't something a fractional CFO does alone — it sits alongside your accountant and often a lawyer. Where a CFO adds value is flagging that the review is overdue and modelling the cash and tax impact of the options before you commit to one. Our fractional CFO service is built around exactly that kind of forward planning.
What reporting does a $10M+ builder actually need?
Project-level, not business-level. Four things, specifically:
Forecast margin per job, re-estimated monthly — not the original budget rolled forward.
A monthly WIP schedule that shows over- or under-claimed position by job, not just in aggregate.
A rolling 13-week cash flow, because at this size the business is juggling drawdowns, retentions and payroll across multiple jobs at once, and a monthly view is too slow to catch a squeeze.
Debtor days by client, because one slow-paying head contractor can quietly fund itself off the rest of the business's working capital.
A blended P&L cannot produce any of these. At $10M+ turnover, running six or seven concurrent projects on business-wide numbers alone means the business is, in effect, flying on instruments that only tell you the average altitude of the whole fleet.
Five signs your structure hasn't kept up with your revenue
Plant, vehicles or property sit in the same entity signing new building contracts.
Your overdraft or facility limit hasn't been reviewed since you were running two-thirds of today's turnover.
You can name your total revenue for the year but not which of your live jobs is currently forecasting the worst margin.
Your accountant last looked at your structure — not just your tax return — more than two years ago.
A bank, surety or insurer has asked a question about your structure or reporting that took more than a day to answer properly.
Two or more of these, and the structure is now the thing limiting how much work you can safely take on — not the market, and not the team.

Frequently asked questions
What changes for a construction business past $10M turnover?
Three things move at once: risk concentration, working capital and reporting. Assets sitting in the trading entity become a real exposure at contract sizes that can produce a meaningful dispute; the funding gap between costs and progress claims grows in proportion to turnover; and business-wide reporting stops being adequate once you're running six or seven concurrent projects.
Why does growth make construction cash flow worse?
Because every project front-loads costs and back-loads receipts. Winning more work means funding more upfront spend before the corresponding claims land, so cash gets tighter as revenue rises — which is why builders commonly hit their worst cash position in their best growth year. The profit is real; it just hasn't arrived yet.
Should a builder separate assets from the trading entity?
For most builders past $10M, yes in principle — but the right structure depends on contract types, licensing, home-warranty eligibility and the existing tax position, so it needs specific advice rather than a general rule. What's general is that restructuring is far cheaper and cleaner done before a growth phase than during or after one.
What does it cost to restructure reactively versus proactively?
There's no fixed figure, but restructuring after a dispute or a bad year — with live contracts, creditor consents and surety arrangements already in place — routinely costs several times what the same restructure would have cost planned ahead at $8–10M turnover, once additional legal, stamp duty and advisory time are counted.
What reporting does a $10M+ builder need?
Project-level rather than business-level: forecast margin per job, a monthly WIP schedule, a rolling 13-week cash flow, and debtor days by client. A blended P&L can't tell you which of seven live jobs is losing money, and at this size one bad project can absorb the profit from the other six.
Who should be involved in a structure review at this size?
Your accountant and often a lawyer for the legal and tax mechanics; a fractional CFO's role is usually to flag that the review is overdue and to model the cash and tax impact of the options before you commit, working alongside — not instead of — the other two.
