Plant and Equipment Finance: The Decision That Is Not About the Machine

A contractor wins a three-year maintenance contract and needs a second excavator. A dealer offers a competitive rate over five years with a modest balloon. The numbers work against the contract, the machine arrives, and everyone gets on with it.

Eighteen months later the same contractor is shortlisted for the largest job they have ever bid, needs to fund eight weeks of wages and materials before the first progress claim is paid, and discovers their bank will not extend the overdraft — because the plant financier holds a general security agreement over the whole business. The machine was affordable. The finance structure was not.

The decision that is not about the machine

Plant finance is usually approached as a shopping exercise: find the machine, find the cheapest rate, sign. That misses the three consequences that actually matter for a civil contractor.

• It changes how your balance sheet reads. Prequalification schemes and clients assess financial capacity from your accounts. Plant debt affects gearing, liquidity and net asset position, and the effect is not always in the direction people assume.
• It consumes security and lender appetite that working capital also needs. This is the growth trap: the contractor who has financed a fleet cannot fund the working capital to run the work the fleet was bought for.
• It converts variable cost into fixed cost. Hire stops when work stops. A finance repayment does not, and civil construction is cyclical.

The first is covered from the assessor’s side in our guide to demonstrating financial capacity in tenders. The second is the theme of this guide. The third is why the hire-versus-buy discussion in our guide to plant hire agreements should be settled before this one starts — this guide assumes you have already decided to own. What ownership then costs per hour depends on availability, which is the subject of our guide to plant maintenance, availability and the workshop. One input that belongs in any own-versus-hire comparison is the rebate covered in our guide to fuel tax credits, which lowers the true cost of every off-road hour.

The instruments and how they differ

Instrument	Who owns the machine	Typical shape	Common use in civil
Chattel mortgage	You, from day one. The financier registers a security interest	Fixed term, fixed repayments, often a residual at the end	The dominant structure for Australian civil plant
Finance lease	The financier. You lease and usually have an option at the end	Fixed term with a residual value	Less common than it was, still used
Operating lease / rental	The financier or rental company. You return it	Term rental, no ownership intent	Where flexibility matters more than cost per hour
Rent-to-own or rental with purchase option	Rental company, until you exercise	Rental with some or all payments crediting a purchase price	A genuine middle path — try the machine, decide later
Dealer or manufacturer finance	Varies by structure	Often subsidised rates tied to a purchase	Frequently the cheapest headline rate; read the security terms
Bank equipment facility	You	A line under your existing banking relationship	Simplest to manage, and keeps everything with one lender — which is both the advantage and the risk
Unsecured or short-term lenders	You	Fast approval, higher cost, shorter term	Occasionally justified for a genuine bridge; expensive as a strategy

The distinctions that matter commercially are not the labels but three underlying questions: who owns the asset, what security is taken, and what happens at the end of the term. Two facilities with the same rate and term can differ enormously on all three.

Ownership, tax and where to get advice

Different structures are treated differently for income tax, GST and depreciation, and the differences are genuinely material to the total cost. They are also the part of this subject most likely to be wrong in a general article, because the rules change frequently — accelerated depreciation and immediate write-off measures in particular have been introduced, extended, varied and allowed to lapse repeatedly, with different thresholds in different years.

So this guide states no tax treatment and no thresholds. What it does say is what to ask your accountant, before signing rather than after:

• Under each structure being considered, when can GST be claimed, and how does that interact with our reporting basis?
• What is deductible, and over what period — and how does that compare between structures over the full term rather than in year one?
• What depreciation or write-off measures apply to this asset in the current year, and are there timing rules about when it must be installed and ready for use?
• Does it matter whether the machine is bought by the operating entity or a separate asset entity, for tax, for asset protection, and for how our accounts will read to a prequalification assessor?
• How will each structure appear in the financial statements we submit for prequalification?

That last question is the one contractors never ask and should. Accounting standards have changed how leases are presented for entities that apply them, and structures once described as “off balance sheet” frequently are not any more. If your reason for choosing a structure was that it keeps debt off the balance sheet, verify that is still true for the way your accounts are actually prepared before relying on it.

Balloons and residuals — the trap at the end

A balloon or residual is an amount deferred to the end of the term. It reduces the monthly repayment, which is why it is offered and why it is accepted.

The risk is straightforward: at the end of the term you owe the residual, and the machine may be worth less than it. That gap is real money, payable at once, and it arrives at whatever point in the cycle the calendar chooses.

What makes the gap more likely:

• Higher-than-expected hours. Resale is driven by hours and condition. A machine that worked harder than planned is worth less than the residual assumed.
• A long term on a hard-working asset. Attachments, wear items and undercarriage age faster than the finance does.
• A soft market at the wrong moment. Used plant values move with the construction cycle, and everyone’s residual falls due in the same downturn.
• Rolling the gap into the next machine. The common response, and the one that compounds — each new facility carries the previous shortfall, and the position deteriorates quietly for years.

The disciplines that manage it: keep the residual conservative even though it raises the repayment; run the numbers on what the machine is realistically worth at term end at your actual expected hours; and set aside for the residual during the term rather than meeting it from whatever cash is available on the day. The monthly reporting rhythm in our guide to job costing and cost control is the natural place to track it.

Security: the clause that blocks your bank

The most consequential term in a plant finance agreement is usually not the rate. It is what the financier takes security over.

Security	What it covers	Consequence
Specific security over the asset	That machine only	Clean. The rest of the business stays available to other lenders
General security agreement	All present and after-acquired property of the business	Encumbers everything, including debtors — which is what working capital lending relies on
Cross-collateralisation	Multiple assets securing multiple facilities	You cannot sell or refinance one machine without dealing with the whole arrangement
Director’s guarantee	The director personally	Standard for SMEs, but know whether it is limited or unlimited, and whether it survives sale of the asset
Property security	A mortgage over real property, often the family home	Sometimes gets a better rate. Understand exactly what is being risked for that saving

The second row is the one that causes the failure described at the start of this guide. A general security agreement given to a plant financier for a single machine can take priority over, or prevent, the debtor-backed facility a contractor needs to fund a large contract. The finance was cheap; the opportunity cost was the next job.

Practical protections:

• Ask what security is required before you compare rates. A slightly higher rate on specific security is frequently the better deal.
• Push back on a general security agreement for a single asset. It is often negotiable, particularly with dealer and specialist financiers, and asking costs nothing.
• Tell your bank before you sign. If they hold a general security, a competing registration may breach your facility terms.
• Check the registrations. Security interests are recorded on the national personal property securities register, and you can search what is registered against your own business. Stale registrations from paid-out facilities are common and quietly reduce your borrowing capacity.
• Read the default provisions. Cross-default clauses can mean a problem with one facility triggers default on another.

The related point for contractors who also hire plant: a machine on your site that you do not own may carry someone else’s registered interest, which is covered in our guide to plant hire agreements.

What the lender is actually assessing

Understanding the assessment makes applications faster and cheaper, and it overlaps substantially with what a prequalification assessor looks at.

• Serviceability — can the business meet the repayment from operating cash flow, evidenced by tax returns and financial statements. Businesses structured to minimise taxable profit frequently present poorly here, which is the same problem our guide to demonstrating financial capacity describes in a tendering context.
• The asset — type, age, hours, condition and resale liquidity. A common machine from a major brand is easier and cheaper to finance than a specialised one, because the financier’s fallback is selling it.
• Contract backlog — secured work supporting the repayment. This is where a signed term contract genuinely helps, and it is worth presenting properly rather than mentioning.
• Existing commitments — every other facility, its balance and its security.
• Deposit or equity — how much you are contributing.
• Credit history, including payment behaviour to the tax office, which lenders increasingly see.

Two things improve the outcome disproportionately. Presenting a short written case — the machine, the work supporting it, the utilisation assumption and the repayment against forecast cash flow — rather than a bare application. And explaining anomalies before they are found; a loss year with a two-paragraph explanation is a different proposition from one an assessor discovers.

What plant debt does to your prequalification

The link that makes this a tendering topic rather than purely a finance one.

Prequalification schemes and large clients assess financial capacity from your accounts, typically looking at liquidity, gearing, net assets and profitability, and using those to set a maximum contract value you may hold. Plant finance moves several of those at once:

Effect	How it reads
Asset and matching liability added	Gearing rises. Heavily geared balance sheets attract lower assessed capacity
Next twelve months of repayments are a current liability	Working capital and current ratio fall — often the single most heavily weighted measure
Deposit paid from cash	Cash reserves fall, which is also assessed
Depreciation reduces reported profit	Profitability measures weaken even where cash generation is healthy
Plant held in a separate asset entity	The operating entity that gets assessed shows lease costs and no assets, which can read worse rather than better unless explained

The timing point is the actionable one. If your prequalification renewal is assessed on year-end accounts, a large plant acquisition immediately before year end will be reflected in full while the revenue it generates will not. Where the decision has any flexibility, understanding which financial year an acquisition lands in is worth a conversation with your accountant. Our guide to civil contractor prequalification in Australia covers how the schemes assess, and none of this suggests concealing anything — the point is to know how a genuine decision will be read, and to explain it in the submission.

Term matching and committed work

Two rules that prevent most plant finance failures.

Match the term to the asset’s working life, not to the repayment you would like. Financing a machine over a term longer than you will realistically keep it guarantees you owe money on an asset you no longer want, and the temptation to extend the term to make a repayment fit is exactly how that happens. Wear items, attachments and technology upgrades all have shorter lives than the machine and should not be financed on the machine’s term.

Finance against committed work, not expected work. A signed multi-year term maintenance contract is committed; a strong pipeline is not. This is the same warning our guides to mining and resources civil works and scaling a civil contracting business give about cyclical exposure, and plant finance is the mechanism that converts a downturn into an existential problem rather than a lean year.

Where the machine is genuinely bought for a specific contract, two further checks are worth making. Does the contract term exceed the finance term, or will you be paying for the machine after the work that justified it has ended? And what happens if the contract is terminated for convenience — a right most government contracts reserve — while the finance runs on?

The downturn test

The single most useful exercise in this guide, and it takes an hour.

Model the business with revenue reduced by a substantial proportion for six months — the kind of drop a wet season, a lost panel or a funding pause actually produces. Then ask:

• What are total monthly finance commitments across every facility?
• Can they be met from the reduced revenue after wages and creditors?
• Which costs are genuinely variable, and how quickly can they actually be reduced?
• What happens if a residual falls due during that period?
• If a machine had to be sold, would the sale clear the finance, and how long would selling take?
• Would any of this trigger a default or cross-default?

Contractors who fail this test are not necessarily over-committed, but they should know it before signing rather than during. And it interacts with payment risk: the modelling in our guide to cash flow in civil construction contracts shows how quickly a slow-paying client consumes reserves, and fixed finance commitments remove the flexibility that would otherwise absorb it.

New, used and the hours question

	New	Used
Finance availability	Widest, lowest rates, longest terms	Narrower, higher rates, shorter terms, and age limits
Depreciation	Steepest in the early years	Already absorbed by someone else
Reliability and downtime	Warranty; downtime is someone else’s cost	Downtime is your cost, and it is the cost that hurts on a programme
Prequalification and tender presentation	Fleet age is assessed — see plant and equipment schedules	Needs a maintenance story to be persuasive
Technology	Machine control, emissions and safety systems fitted or ready	Retrofitting is possible but adds cost — see machine control and GNSS

For used purchases, hours are the number that matters and the one most easily misread. Ask what the hours were doing — a machine that spent its life idling on standby has different wear from one that worked continuously — and get an independent inspection rather than relying on a service history supplied by the seller. On any significant purchase, check the personal property securities register before paying, because buying a machine with an unreleased security interest over it is a problem you inherit.

Refinancing and equity release

Two options that solve a short-term problem and can create a long-term one.

Refinancing — replacing an existing facility, usually to reduce repayments — is legitimate where rates have moved or the original term was poorly structured. It is a warning sign where the purpose is simply to lower repayments the business can no longer meet, because it extends the term on a depreciating asset and increases the chance of owing more than the machine is worth.

Equity release — borrowing against machines you own outright — converts an unencumbered asset into cash plus a commitment. It can be the right move to fund working capital for a large contract, and it is far better than not being paid for work you cannot fund. But it removes the buffer that unencumbered plant represents, and it is worth being honest about which situation you are in: funding growth, or funding a loss.

If working capital rather than plant is the real constraint, address that directly. The statutory payment regime in our guide to security of payment in Australia, and the payment terms discussion in cash flow in civil construction contracts, are frequently a better answer than borrowing against the fleet.

A decision framework

Six questions, in order. If any answer is uncomfortable, the answer to the purchase is probably not yet.

#	Question	Why it comes here
1	Is this utilisation real and committed, or forecast?	Committed work services debt. Forecasts do not
2	Have we compared owning against hiring on measured cost, not instinct?	The prior decision. Requires an internal plant rate — see job costing and cost control
3	What security is required, and what does it leave available for working capital?	The constraint contractors discover too late
4	Does the term match the working life, and is the residual conservative?	Prevents owing more than the machine is worth
5	How will this read on the accounts our next prequalification is assessed on?	Capacity to bid is an asset too
6	Does the business survive the downturn test with this commitment added?	The one that decides whether a bad year is survivable

A final observation worth stating plainly. Plant is the most visible measure of a civil business and the easiest to mistake for progress. Machines in the yard feel like growth; capacity to bid, fund and deliver work is growth. The contractor who keeps borrowing capacity in reserve can take the job that arrives unexpectedly. The one whose capacity is fully deployed in iron can only watch it. That trade-off is the real subject of this guide, and it is the same one our guide to the go/no-go decision makes about bidding: the capacity you preserve is what lets you say yes to the right thing.

Checklist

• Have you decided to own rather than hire, on measured cost rather than instinct?
• Is the utilisation supporting this machine committed work or forecast work?
• Do you know what security each financier requires, before comparing rates?
• Have you asked whether a general security agreement can be reduced to specific security?
• Have you told your bank, and checked whether a competing registration breaches your facility?
• Have you searched the personal property securities register against your own business for stale registrations?
• Are there cross-default provisions linking this facility to others?
• Is there a director’s guarantee, and is it limited or unlimited?
• Does the finance term match the realistic working life of the machine?
• Is the residual conservative against expected hours and a soft resale market?
• Are you setting aside for the residual during the term?
• Have you asked your accountant about GST timing, deductibility, write-off measures and entity structure — before signing?
• Have you confirmed how the structure will actually appear in your financial statements?
• Do you know how this will read on the accounts your next prequalification is assessed on, and which financial year it lands in?
• Have you run the downturn test across every facility together?
• If a machine had to be sold, would the sale clear the finance?
• On a used purchase, have you had an independent inspection and checked for registered interests?
• If you are refinancing, is it because rates moved — or because the repayment is no longer affordable?

The short version

• The finance structure decides how your balance sheet reads, what security remains for working capital, and how fixed your costs become. The machine is the least of it.
• Plant finance and working capital compete for the same security and the same lender appetite. That is the growth trap.
• The most consequential term is usually the security, not the rate. A general security agreement for one machine can block the facility that funds your next job.
• Ask what security is required before comparing rates, push back on general security for a single asset, and tell your bank before signing.
• Balloons lower the repayment and defer the risk. Keep residuals conservative and set aside for them during the term.
• Rolling a residual shortfall into the next machine compounds quietly for years.
• Match the term to the working life, and finance against committed work rather than a pipeline.
• Plant debt raises gearing and cuts working capital ratios — often the most heavily weighted prequalification measures. Know which financial year the purchase lands in.
• Do not rely on a structure being “off balance sheet” without confirming it is still true for how your accounts are prepared.
• Run the downturn test across all facilities together before signing, not during.
• Machines in the yard feel like growth. Preserved borrowing capacity is what lets you take the job that arrives unexpectedly.
