Construction CFO services: the profit you keep is decided at bid time
By the time a job closes out, its margin is history — the profit was set when you bid it and defended, or lost, while you built it. Our fractional CFO work for Ontario contractors closes the estimate-to-actual loop on every job, plans cash around 10% holdbacks, turns equipment decisions into arithmetic, and shapes the balance sheet your surety underwrites.

Margin is set at bid time and defended during the build
A contractor's profit is made twice — once in the estimate, once in the field — and lost anywhere in between. Our fractional CFO work for Ontario general contractors and subcontractors is built around that fact: a live estimate-to-actual loop on every job, cash planning that treats holdbacks honestly, equipment decisions run as math rather than yard preference, and a multi-year plan for the balance sheet your surety prices. It sits on top of disciplined job-cost books — our construction bookkeeping service — with fixed fees quoted after a discovery call.
Bid margin discipline: close the estimate-to-actual loop
Most contractors know the margin they bid; far fewer know the margin each job actually finished at, by cost code — and the space between those two numbers is where construction companies quietly fail. The loop we run is simple and relentless: every awarded job gets a budget by cost code, costs post against those codes weekly, and each month we compare projected final margin against bid margin while there is still time to act on the fade. Patterns surface fast — one estimator's labour codes always run hot, one class of work never hits its number, site supervision is systematically underpriced — and the next bid gets smarter for it.
Change orders are the other half of the discipline. Priced, signed, and billed change orders protect margin; verbal ones become disputed invoices and then free work. The rule we hold clients to: no changed work starts before written acknowledgement of the price, and month-end treats unsigned change orders as exactly the receivable risk they are.
Holdbacks: you are financing ten percent of your own work
Under Ontario's Construction Act, 10% of every progress billing is held back until the lien period expires — and since plenty of work is bid at margins near that number, the holdback receivable is often your entire expected profit: earned, invoiced, and untouchable. We forecast job cash on the 90% you can collect, track holdback balances by project, and diarize releases so the holdback invoice goes out the day it is due instead of surfacing at year-end. The Act's prompt-payment clock — 28 days for an owner to pay a proper invoice, seven more for the contractor to pay subs — puts legal dates under the rest of the receivable, and we build the forecast on those dates and flag who is not honouring them.
The same mechanism works in your favour downstream: the holdback you retain from subcontractors is financing you are entitled to under the Act, and releasing it early is a gift your cash forecast should at least know it is giving.
Equipment: rent until utilization proves the purchase
The default answer on iron is rent, with the burden of proof on buying. Ownership wins only when a machine's utilization is high enough that its full monthly cost — financing, insurance, repairs, storage, floats between sites — beats the rental invoices it replaces, so we make the call from a utilization log rather than a gut feel:
- Track rental spend by machine class for two quarters; repeated rentals of the same class are the honest purchase signal.
- Price ownership completely — payments, insurance, maintenance, storage, transport, operator time, and a realistic resale value, not just the finance payment.
- Count the bonding side effect — equipment debt erodes the working capital your surety measures, so a cheap machine can quietly cost you bonding room.
Bonding capacity is a balance-sheet project measured in years
Sureties underwrite your financial statements, so bonding capacity grows the way balance sheets grow: slowly and on purpose. What the underwriter reads, and what moves it:
| What the surety reads | Why it moves your limits |
|---|---|
| Working capital | The core input for single-job and aggregate limits; equipment debt, large shareholder draws, and slow receivables all erode it |
| Retained equity | Bonusing every dollar out each year caps the program; profit left in the company grows it |
| WIP schedule quality | Believable cost-to-complete estimates and steady margins build trust; wild swings between drafts destroy it |
| Billing position | Chronic underbilling reads as estimating weakness; healthy overbilling reads as cash discipline |
| Bank support | A committed operating line signals you can carry a bad job without starving the good ones |
The practical program follows from the table: leave enough profit in the company each year — a decision that runs through our construction tax planning, because the salary-dividend call has a bonding dimension — keep a clean quarterly WIP schedule, and never surprise the surety. Contractors taking US jobs add state registration, sales tax on materials, and payroll layers on top; our cross-border page for contractors covers that side in depth.
Common questions.
We already have a bookkeeper — what does the CFO layer add?
The bookkeeper records job costs; the CFO layer turns them into decisions: margin-fade reviews, holdback and cash forecasting, equipment calls, and the multi-year balance-sheet plan behind bonding capacity.
How quickly can bonding capacity actually grow?
A meaningful step usually takes one or two clean year-ends — profit retained, working capital built, and a WIP schedule the surety trusts. There is no shortcut, which is exactly why the plan starts now.
Do you review individual bids?
Yes, usually the large or unusual ones. We pressure-test the cost buildup, margin, cash curve, and holdback timing before you commit; the estimate itself stays yours.
