A construction Virtual CFO connects finance to how jobs are delivered: progress claims, variations, retentions, subcontractor exposure, and WIP. Instead of “monthly P&L only,” you get:

• Cash forecasting built around claim cycles and payment schedule timing
• Job margin reporting that isolates labour recovery, prelims, plant, and subbies
• WIP discipline to prevent “paper profit” and late-stage loss surprises
• Risk controls for insolvency-heavy market conditions (credit, tax, and contract discipline)

You forecast in layers, not a single number. We run a rolling cash forecast with three scenarios: Best case (on-time approvals), Expected (average delay), and Protective (late payment/dispute).

• Map each project’s claim dates, assessment dates, and expected payment windows
• Separate “claimed,” “certified,” and “cash received” so optimism doesn’t become insolvency
• Tag high-risk claims (variations, incomplete docs, disputed scope) and hold a liquidity buffer

A claim rhythm is the repeatable weekly workflow that protects cash: cut-off → measure → evidence → submit → chase → reconcile → allocate. Builders run out of cash when claims aren’t treated like a production system.

• Late claims push receipts out by weeks (while wages/suppliers stay weekly)
• Missing variation approvals turn “revenue” into “arguments”
• Retentions compound cash holes as workload grows

Treat retentions like a receivable portfolio with an ageing report and a release calendar (PC + defects end). Then actively reduce the amount stuck in retention.

• Track retention by job, tier (head vs sub), and expected release date
• Negotiate replacement security (bank guarantee / bond) where commercially viable
• Schedule defects close-out to accelerate release, not “when we get to it”
• Forecast retention as a separate cash line (don’t hide it in “revenue”)

NSW has requirements aimed at protecting subcontractor retention money on certain projects. The trigger can depend on project value and the contract chain. Practically, a CFO will:

• Identify which projects meet the threshold and whether you’re a head contractor holding retention
• Set up the correct bank structure and internal controls (separate ledger tracking, reconciliations)
• Align subcontract language and reporting so retention movements are audit-ready

Note: get legal advice for your specific contract structure and jurisdiction.

Where applicable, trust-style payment structures change “who holds cash” and “when you can touch it.” Your CFO must redesign the cash workflow so payroll, suppliers, and subbies still get paid on time.

• Separate trust flows from operating cash (no accidental cross-funding)
• Rebuild weekly cash meetings around trust payment dates and documentation readiness
• Price overhead and prelims knowing cash may be “restricted” until compliant documentation is ready

A valid claim (and the right supporting notices) affects how quickly money can be enforced when payment stalls. CFO-level benefit: fewer “stuck” claims and better certainty in cash forecasts.

• Standardise claim templates and required wording (jurisdiction-specific)
• Enforce evidence packs (photos, dockets, delivery confirmations, signed variations)
• Maintain a claim register that links to forecast receipts and dispute status

Payment schedules often become accidental profit leaks when set-offs and backcharges aren’t documented. A Virtual CFO will help you enforce a “proof standard” internally:

• Every deduction must reference the contract clause and quantification method
• Backcharges require evidence (timesheets, invoices, site instructions)
• Variations must be listed separately (claimed / assessed / approved / rejected)

“Control” isn’t only price—it’s scope clarity, measurement discipline, and approval timing. We implement:

• Committed cost reporting (POs/subcontracts approved before work ramps)
• Weekly cost-to-complete updates for high-risk packages (e.g., services, finishes, civils)
• Variation gates: no instruction without documented scope + price pathway

WIP (Work In Progress) is the financial reality of jobs mid-flight: what you’ve earned vs what you’ve billed, and whether costs to complete still fit the budget. “Paper profit” happens when revenue is recognised faster than real margin (or when costs-to-complete are understated).

• Understated costs-to-complete makes jobs look profitable until the final months
• Delayed variations turn expected profit into unrecovered cost
• Retentions and disputed claims create cash pain even when P&L looks fine

True margin includes recovered labour, prelims burn, plant usage, and subcontractor scope creep—plus time-based costs from delays. We build a job margin model that shows:

• Labour recovery (hours × charge-out vs actual wage + on-costs)
• Prelims spend vs budget (site management, temp services, safety, amenities)
• Committed costs (POs/subcontracts) vs budget to stop “late surprises”
• Variation margin separately (so base contract doesn’t get distorted)

Variation control is documentation control. We implement a “variation pipeline”: notice → scope → price → approval → claim → recovery.

• No site instruction without a variation number (even if “TBC”)
• Track ageing: how long each variation sits unpriced or unapproved
• Separate labour/material evidence and mark-ups per contract rules
• Forecast cash recovery timing (variations often pay later than base claims)

Delays are usually margin killers because prelims and overhead keep running while progress slows. Finance needs an early-warning “time cost” view.

• Prelims burn rate per week (and who pays for the extension)
• Liquidated damages exposure vs entitlement position
• Under-recovered overhead if revenue slows but fixed costs remain
• Cash timing: slow progress often means slow claims

In the current market, margin protection is a system, not a “please pay more” email.

• Escalation clauses and procurement plans (lock key materials early)
• Quote validity periods and supplier price confirmation rules
• “Margin at risk” reporting: identify jobs where cost-to-complete is trending up
• Variation discipline for design changes, scope creep, and client-driven upgrades

If you account for GST on an accrual basis, you may need to remit GST when you invoice—even if cash hasn’t landed yet. That means late payments can create a GST-funded cash hole.

• Forecast GST separately from “operating cash”
• Align claim timing so large invoices don’t land right before BAS due dates
• Review eligibility for cash GST accounting (case-by-case) with your tax adviser
• Run debtor discipline: ageing, dispute tracking, and escalation steps

Always confirm GST treatment with your registered tax agent for your entity.

Cash shows survival. Accrual shows profitability. Construction needs both—because you can be profitable and still fail. A Virtual CFO typically:

• Uses accrual + WIP for true job profitability and forecasting
• Uses a cash runway view (weeks of liquidity) for risk control
• Separates “earned revenue” from “billed revenue” to avoid false confidence

The big risks are underpayment exposure (overtime/allowances), misclassification of contractors, and weak time capture. Financially, the damage is margin leakage + compliance cost.

• Job-based timesheets that feed job costing (not “end of week guessing”)
• Allowance and travel rules built into payroll processing
• Labour recovery reporting: what hours cost vs what they should earn on the job

Payroll tax can apply to certain contractor payments depending on the arrangement and state rules. Construction businesses often get caught because contractors can look like employees in practice (exclusive/regular service).

• Review contractor engagements: scope, independence, multiple clients, and documentation
• Separate labour-only vs genuine materials/equipment supply components where appropriate
• Keep contract + evidence packs ready (audit-proofing beats panic later)

This is general information—state rules vary. Get advice for your circumstances.

Many building and construction businesses must lodge a Taxable Payments Annual Report (TPAR) if they pay contractors. The easiest way to stay compliant is to capture data at source:

• Correct legal name, ABN, GST status, address
• Gross payments, GST component, and dates paid
• Clear separation of contractor vs supplier invoices in your accounting system

It’s a monthly pack that answers the questions lenders, owners, and directors actually ask:

• Cash runway + 13-week forecast (with best/expected/protective scenarios)
• Job margin dashboard (top 10 by revenue, top 10 by risk)
• WIP summary and movements (earned vs billed vs cash)
• Debtors ageing by project + dispute list
• Retention ageing + release calendar

• Cost-to-complete creeps up every month “but margin still looks okay”
• Prelims burn exceeds planned weeks due to delays or resequencing
• Variations ageing (unpriced/unapproved) while the work is already done
• Committed costs (POs/subcontracts) exceed budget even before the final trade packages land
• Cash conversion slows: claimed → certified → paid time gap widens

A CFO tests a job against both margin and cash capacity. The key is not “Can we win it?” but “Can we fund it without breaking the business?”

• Cash curve: deposit/claim timing vs supplier and wage timing
• Retention impact: how much cash will be trapped as workload grows
• Risk loading: site constraints, programme risk, subcontractor availability
• Opportunity cost: what jobs will you be forced to decline later due to capacity

The best choice depends on utilisation and cash. We model:

• Utilisation rate (hours used / hours available) and downtime cost
• Maintenance + insurance + registration + storage vs hire all-in rate
• Cash impact: deposits, repayments, and how quickly the asset pays back
• Tax and finance structure review with your adviser (case-by-case)

The goal is to avoid being the “bank” for someone else’s risk.

• Credit discipline: debtor caps, escalation steps, and stop-work triggers
• Cash buffers: minimum cash runway target + protective forecast scenarios
• Supplier and subcontractor strategy: diversify critical trades and materials
• Tax control: BAS/PAYG planning so ATO debt doesn’t ambush cash
• Project selection: reject jobs that are margin-thin and cash-negative

Systems should reduce admin and increase certainty—not create more work. A practical stack usually includes:

• Accounting (e.g., Xero/MYOB) with clean cost codes and consistent job setup
• Job costing + WIP workflow (earned vs billed vs costs-to-complete)
• Timesheets linked to jobs (to stop labour margin disappearing silently)
• PO/commitment tracking (to see future cost before it hits the invoice)
• Claim register + retention register + variation register (three “money leaks” controlled)
