Pay for accepted value, not activity: stage payments, payment claims and buying early

A supplier’s invoice asks for money. Whether that money is actually due is a different question, and the answer lives in the agreement, the evidence and the state of the work, not in the invoice. Many small businesses treat payments for project work as an accounts task: the invoice arrives, someone checks the number matches the quote, and it is paid. That works for routine purchases. For a significant job, such as a new machine, a fit-out, a software build or a building extension, each payment is one of the few moments when the buyer still has real influence over the outcome.

Three decisions shape how well a business uses that influence. The first is how the payments are structured: what events trigger them, and whether those events represent real, checkable value. The second is how each claim is assessed: whether the business checks entitlement and evidence, or just arithmetic. The third is whether to pay for things before they are needed, such as equipment ordered early to protect a schedule, which can reduce one risk while quietly creating several others.

This article covers all three from the buyer’s side, with notes for suppliers who sit on the other side of the same arrangement. It is general information. Contract terms, ownership of goods and payment laws vary, so take advice on a particular agreement.

Paying for progress is normal, and it shapes behaviour

Most significant jobs create value progressively. A machine is designed, built, tested, delivered, installed and commissioned. A fit-out moves through demolition, services, joinery and finishes. Paying in stages is fair, because suppliers need cash to fund labour, materials and subcontractors long before the job finishes.

The question is what each stage pays for. Compare two ways to pay $100,000 for the same job:

• Front-loaded by date: half on signing and half on completion.
• Staged by outcome: amounts released on approved design, a passed factory test, delivery, installation and commissioning.

Both pay the same total. They create different behaviour. Under the first, the supplier has been paid half the price before anything checkable exists, and the buyer’s influence for the rest of the job rests on the final payment alone. Under the second, both parties know exactly what triggers each payment, the supplier is paid as it creates value, and the buyer never pays far ahead of what it has received.

Payment structure also affects suppliers’ willingness to work with you. Slow, unpredictable payment pushes suppliers towards higher prices, aggressive claims or reluctance to commit resources ahead of payment. A predictable process, where suppliers know what evidence is needed and when money will move, is good for both sides.

Set milestones around value you can verify

Before agreeing a payment schedule, test each proposed milestone:

Calendar dates make poor milestones, because they pay for time passing. Percentages of completion invite argument, because “70% done” is a judgement. Defined deliverables with acceptance evidence work best: “design drawings approved”, “factory acceptance test passed with signed records”, “machine installed and producing parts within tolerance”.

Structuring the agreement so each stage has its own deliverable and payment also helps if something goes wrong late. A failure at commissioning does not necessarily erase the fact that design and manufacture were completed and accepted, and the parties know where they stand. Whether that is how the law treats a particular agreement depends on its wording, which is one reason to have significant agreements reviewed.

Assess each claim, do not just process it

When a payment claim arrives, treat it as a submission to be assessed, not a bill to be paid. A short checklist keeps the assessment disciplined:

1. Entitlement. What event in the agreement creates the right to this payment?
2. Completion. Has that event actually happened, by the agreement’s definition?
3. Evidence. Have the required inspections, test records, drawings or certificates been supplied?
4. Value. Which agreed price, rate or approved variation applies?
5. Adjustments. Do any deductions apply under the agreement, such as retention, credits for missed service levels or amounts for defects?
6. Record. Could someone who was not involved understand why this amount was paid?

The most common gap is between physical progress and contractual entitlement. A machine standing on the workshop floor looks finished. If the agreed milestone is “installed and producing parts within tolerance”, and the test parts have not been run, the milestone has not been reached. The inspection and test plans article covers agreeing in advance what evidence each stage must produce.

Two cautions. First, paying a claim does not usually mean the work is accepted. Many agreements say so expressly, but the practical rule is the same either way: acceptance should rest on agreed evidence, not on an invoice being paid. Second, respond on time. If you dispute part of a claim, say which part and why, in writing, and pay the undisputed amount when it is due. For construction work, every Australian state and territory has security of payment laws that set strict timeframes for responding to payment claims, and missing them can make the claimed amount payable regardless of its merits. Check the rules in your state or get advice before you need them.

Buying early protects one risk and creates others

Ordering equipment or materials early is often sensible. A machine has a long lead time, a supplier offers a production slot, a shutdown window is fixed or supply is unreliable. Buying early reduces the risk of late delivery. But once the item exists before it can be installed, a different set of exposures appears:

• Cash is paid out earlier than planned.
• Storage and handling cost money and add damage risk.
• Ownership may be unclear while the item sits at the supplier’s premises.
• Insurance may not cover it where it is, or for whom it is held.
• Supplier failure could leave you having paid for goods you cannot easily recover.
• Preservation matters: bearings, seals, electronics, batteries and calibrated parts can degrade in long storage.
• Design changes made after ordering may make the item wrong, or need rework.

The delay risk has gone down. The technical and financial risk has gone up. The useful question is not “can we get it early?” but “does buying early create more value than the flexibility we give up?”

Before you approve an early order or an early payment, answer eight questions:

1. Schedule: what delay risk does this actually reduce?
2. Reversibility: how likely is the design to change before installation?
3. Cash: how much money moves forward, and can the business carry it?
4. Ownership: who owns the item at each point, and how is that evidenced?
5. Supplier failure: what happens to the item if the supplier stops trading?
6. Preservation: what storage and maintenance does it need, and who does it?
7. Insurance: who carries the risk of loss or damage while it waits?
8. Readiness: when and how will it be inspected and installed?

If those questions cannot be answered, early may simply mean premature.

There are also options between buying early and buying late. Depending on the supplier, a business may be able to reserve a production slot, pay for the long-lead components only, or agree a staged commitment that protects the lead time without freezing the whole design. Compare the cost of reserving and later converting with the cost of buying outright now.

Paying for goods you have not received

If you agree to pay for items held off site, protect the payment:

• Written confirmation of ownership passing to you on payment.
• Identification: the items tagged, photographed and stored separately from the supplier’s other stock.
• Insurance confirmed in writing for the items where they are stored.
• Inspection rights, so you can see the items before and after payment.
• Restrictions on moving or selling them without your agreement.

Ownership of goods held by someone else can be complicated if that business fails, and in Australia the Personal Property Securities Register can affect who has the stronger claim. This is an area where legal advice before payment is worth far more than advice afterwards. The when a key contractor fails article covers security, retention and continuity planning.

A worked example

This is an illustration. A furniture maker commissions a local integrator to supply and install a CNC router with dust extraction for $180,000. The integrator’s standard terms ask for 40% on order, 50% on delivery and 10% on commissioning.

The owner proposes a schedule based on verifiable value instead, and the integrator agrees:

The total is $180,000. The integrator’s cash flow is not much worse than under its own terms, because the biggest payments now follow events it controls.

The factory test passes eight weeks before the owner’s new extension is ready. The integrator asks to be paid the delivery stage now and to store the router at its premises. The owner works through the eight questions. Waiting costs the integrator storage space and cash; paying early exposes the owner if the integrator fails. They agree that the owner will pay half the delivery stage, $27,000, once the integrator confirms in writing that ownership passes on payment, tags and stores the router separately, and confirms insurance while it is stored. The balance of $27,000 is paid on delivery and installation. The owner’s accountant checks the cash effect, and a lawyer reviews the ownership wording.

When the installation claim arrives, two of the five extraction ducts are not connected and the electrical test certificate has not been supplied. The owner responds within the agreed time, in writing: the milestone is not yet complete, these are the two missing items, and payment will follow when they are done. The integrator finishes the following week, and the claim is paid in full on the next payment run.

How this applies to a small Australian business

• Treat significant payments as control points, not routine invoices.
• Base milestones on verifiable outcomes, not dates or percentages.
• Define the evidence for each stage before work starts.
• Assess each claim against entitlement, completion, evidence and value.
• Respond on time, in writing, and pay undisputed amounts when due.
• Test early orders against the eight questions before approving them.
• Protect payments for off-site goods with ownership, identification, insurance and inspection.
• Check state payment laws for construction work, and take legal advice on significant agreements.

If you are the supplier, the same thinking helps you: propose milestones tied to events you control, with clear evidence, so you can claim confidently and be paid without argument.

Signals worth watching

• Large deposits before anything checkable exists.
• Milestones defined as dates or percentages.
• Claims paid without anyone checking the milestone definition.
• Equipment paid for and stored at a supplier’s premises with no written ownership terms.
• Long-lead items ordered before the design they depend on is settled.
• Payment disputes that arise because nobody agreed what “complete” meant.

Common mistakes

• Treating the supplier’s claimed amount as the starting truth.
• Equating visible progress with entitlement.
• Assuming payment means acceptance.
• Missing response deadlines for disputed claims.
• Buying early without counting cash, storage, insurance and ownership.
• Front-loading payments to win a supplier’s goodwill.

Frequently asked questions

Is a deposit unreasonable? No. A modest deposit for genuine early costs, such as engineering or ordering custom parts, is common and fair. A large deposit before anything checkable exists shifts risk to the buyer.

What if the supplier will not accept milestone payments? Ask why. Sometimes the supplier has real early costs that can be met by a stage tied to ordering materials. If they refuse any structure, factor that into your choice.

Should we hold retention? Sometimes. It protects against defects and incomplete work, but it costs the supplier cash and some states regulate it for construction work.

Do security of payment laws apply to us? They apply to construction work and related goods and services, and the details differ by state. Check with your state’s regulator or a lawyer.

How do we value partly completed work if a job ends early? That depends on the agreement and the law. Clear stages with their own deliverables make it far easier.

Questions to ask

• What exactly triggers each payment, and how will we know it has happened?
• How far ahead of the value we have received are we paying?
• What evidence must the supplier provide with each claim?
• Who assesses claims, and how quickly must we respond?
• What does buying this early give us, and what does it cost?
• If the supplier failed tomorrow, what would we own and what would we have lost?

Bringing it together

Payments for significant work are control points. Structure them around verifiable value, so the supplier is paid as it creates something you can check and you never pay far ahead of what you have received. Assess each claim against entitlement and evidence, respond on time and pay what is due. Treat buying early as a trade, not a free protection: count the cash, storage, ownership, insurance and flexibility you give up, and protect any payment for goods you do not yet hold. Done well, this is fairer to suppliers and safer for the business.
