Getting Paid: Invoicing, Late Payments and Debt Recovery in Australia

You quoted the job, you did the work, the client was happy, and the invoice went out. That was weeks ago. The money is not in your account, your suppliers still expect to be paid on time, and you are effectively lending money to someone who is not paying you for the privilege.

This is the most common way a profitable Australian small business runs out of cash. Profit is an opinion; cash is a fact. A business can be booked out for months and still fail because the gap between doing the work and being paid for it grew wider than its buffer.

The useful thing about late payment is that it is not random. It is a process problem, and processes can be fixed. Businesses that get paid quickly are not luckier or tougher than you — they set terms before starting, invoice correctly and immediately, make paying frictionless, and follow a consistent escalation ladder instead of stewing for a month and then sending an angry email at 11pm.

This guide covers both halves: stopping the problem upstream, and recovering the money when prevention has already failed.

Stop the problem upstream

Every dollar of effort you put into prevention is worth roughly ten spent on recovery. Recovery costs you time, goodwill, fees and often a discount. Prevention costs you a few paragraphs in a document you write once.

Put payment terms on the quote, not just the invoice

This is the highest-leverage change most sole traders can make, and it takes an afternoon. Your payment terms are part of the deal, so they belong in the document the client agrees to — the quote or engagement letter — not first revealed on the invoice after the work is done.

Your quote should state, in plain language:

• The total price and whether it includes GST
• What is included and, just as importantly, what is not
• The deposit required before work starts, and that the booking is not confirmed until it is received
• When you will invoice — on completion, at milestones, or monthly in arrears
• How long the client has to pay, and that this is a term of the contract
• What happens if they do not pay: any late fee or interest, suspension of work, and recovery costs
• Ownership of goods until paid in full, if you supply materials

Getting the quote accepted in writing — a reply email saying "yes, go ahead" is enough for most small jobs — converts a vague understanding into an agreement you can point to later. Verbal agreements are contracts too, but they are miserable to prove.

Choose your terms deliberately. Shorter terms are normal for residential and consumer work; longer terms are common with larger commercial clients and government, whose accounts payable runs on a fixed cycle regardless of what your invoice says. If a big client's standard terms are longer than you can survive, price for it or negotiate a milestone structure — do not silently absorb it.

Take a deposit before you start

A deposit funds materials so you are not financing the client's job on your own credit card. It filters out clients who were never going to pay, which is worth more than the deposit itself. And it changes the relationship: a client with money already committed behaves differently to one who has risked nothing.

Set it to at least cover your out-of-pocket costs for materials and mobilisation, and make it a condition of booking rather than a request. "I can hold that week for you once the deposit lands" is a normal, professional sentence.

Consumer law and some state rules constrain how deposits and prepayments work in certain trades, particularly where the work is regulated by a state building or licensing authority. If you are in a licensed trade, check what your state permits before setting a deposit policy.

Use progress claims on anything long

If a job runs longer than a few weeks, do not wait until the end to invoice. Break it into milestones tied to observable events — site prep complete, frame up, fit-off, design approved, stage two delivered — and invoice at each one.

Progress claims keep cash moving so you are never carrying the whole job, and they surface a payment problem early. A client who does not pay the first progress claim is telling you something valuable at a point when you can still stop work, rather than after you have sunk everything into it.

Write into your quote what happens if a progress claim goes unpaid: you are entitled to suspend work until it is paid. Suspension is a far stronger lever than a reminder email, but only if the client agreed to it upfront — and in construction the right to suspend interacts with security of payment legislation, so see that section below.

Credit-check new commercial clients

For consumer work this is usually overkill. For new commercial clients, especially where you are extending real credit or committing serious materials, spend ten minutes:

• Look up the ABN on ABN Lookup at abr.business.gov.au — confirm the entity is active, GST-registered if it claims to be, and that the trading name connects to the entity you are contracting with
• Check ASIC's register for companies, and record the exact company name and ACN, not the trading name
• Ask for trade references on larger jobs, and actually call them
• Consider a paid credit report through a commercial credit bureau for significant exposure

The most expensive mistake here is contracting with the wrong legal entity. "Dave's Excavations" might be a sole trader, a company, or a trust. If you sue the trading name instead of the entity behind it, you have sued nobody. Put the full legal entity name and ABN or ACN on the quote and the invoice.

Register on the PPSR when you supply goods on credit

If you supply goods the customer takes possession of before paying — materials, equipment, stock, plant on hire — a retention of title clause in your terms is only half the protection. To make it effective against other creditors if the customer goes under, you generally need to register a security interest on the Personal Property Securities Register at ppsr.gov.au.

Registration is inexpensive and fast. Not registering is brutal: unregistered retention of title claims routinely lose to banks and administrators, and businesses have watched goods they were never paid for get sold out from under them. Timing and how you describe the collateral both matter, so if this is a regular part of your business, have it set up properly once.

Getting the invoice right

An invoice missing a required element is a free excuse for a slow payer. Large organisations in particular run accounts payable systems that reject non-compliant invoices automatically, and nobody tells you — the invoice simply sits in a queue while you assume it is being processed.

If you are registered for GST, a tax invoice must contain:

Element	What it means in practice
The words "Tax invoice"	Prominent, at the top
Your identity	Your business or legal entity name as it actually is
Your ABN	Non-negotiable — without it the buyer may be required to withhold tax from the payment
Date of issue	The date the invoice is issued
Description of what was supplied	Items or services, with quantity where relevant — enough detail to identify the supply
The GST	Either the GST amount shown separately, or a statement that the total price includes GST
The buyer's identity or ABN	Required once the invoice exceeds the threshold the ATO sets for higher-value invoices

The ATO sets that higher-value threshold and publishes the rules for mixed supplies where only some items are taxable. Check the current requirements on the ATO website rather than relying on what a mate told you.

If you are not registered for GST, you issue an ordinary invoice. Do not label it a tax invoice and do not show a GST amount — charging GST when you are not registered is a real problem, not a technicality.

Beyond the legal minimum, a few additions get you paid faster: an invoice number and the client's own purchase order or job reference, since commercial clients frequently will not pay without a PO number; the due date written as an actual calendar date rather than a number of days, because "Due 12 September 2026" cannot be argued with; your bank details prominently, plus every other way to pay; and a one-line reference to your agreed terms.

Send the invoice the day the job is finished. Not at the end of the week, not at the end of the month. Every day of delay on your side is a day of delay on theirs, and it quietly signals that the money is not urgent to you.

business.gov.au publishes free invoice and tax invoice templates containing the required elements — a reasonable starting point if you are not yet using accounting software.

Make paying easy

Friction kills collection rates. Every step between the client deciding to pay and the money leaving their account is a chance for the payment to be deferred.

Take payment at the point of completion. For on-site trades and mobile services this is transformative. Tap-to-pay on a phone means no terminal to carry and no invoice to chase — you present the total while you are still standing in front of the customer. The merchant fee is real, but it is almost always cheaper than months of chasing and a partial write-off. Compare providers on rates, settlement speed and surcharging, noting that surcharging rules limit you to passing on your actual cost of acceptance.

Use direct debit for recurring work. For retainers, maintenance contracts and regular service visits, direct debit converts an accounts receivable problem into a scheduling problem. Clients on direct debit pay on time by default, and you learn about a failure immediately rather than a month later. You need proper authorisation and clear disclosure, which any reputable provider handles.

Automate reminders. Every mainstream Australian accounting package sends scheduled reminders before and after the due date without you touching anything. They are unemotional, consistent and land at the right time, which is exactly what a manual process never manages — and they create a documented trail if you later escalate.

Offer more than one payment rail. Bank transfer, card, and a payment link in the invoice email. Some clients pay whatever is easiest the moment they open the email; if that option is not there, they close the email.

The escalation ladder

When prevention has failed, work the ladder in order. Each rung costs more than the last in money, time and relationship, so do not skip ahead — but do not stall either. The common mistake is not being too aggressive; it is doing nothing for two months and then jumping straight to a lawyer.

Rung	What it is	Tone	Cost	Move on when
1. Friendly reminder	Email or SMS, assumes an oversight	Warm, no accusation	Free	No payment or reply after a short period
2. Formal reminder	Written, states the overdue amount and a deadline	Businesslike	Free	Deadline passes
3. Letter of demand	Formal written demand before further action	Firm, factual	Free to low	Deadline in the letter passes
4. Mediation / small business commissioner	ASBFEO or state commissioner assisted resolution	Neutral	Low	Client refuses or mediation fails
5. Debt collector or lawyer	Third party pursues on your behalf	Professional pressure	Commission or fees	Debtor still refuses
6. Tribunal or court	Formal claim for judgment	Legal	Filing fees plus costs	Judgment obtained, or claim not viable
7. Statutory demand (companies only)	Formal demand that can lead to winding up	Serious, last resort	Legal	Only where the debt is clear and undisputed

1. The friendly reminder

Send it the day after the due date and assume it is an oversight, because most of the time it is. Keep it short: invoice number, amount, due date, payment details, and an offer to resend. No emotion, no apology for asking — you are not being rude by asking to be paid for work you completed.

Phone as well as email, especially for larger amounts. A two-minute call to accounts payable frequently uncovers the real problem: the invoice was never received, it is missing a PO number, it went to the wrong address, or it is waiting on one person's approval.

2. The formal reminder

If the friendly reminder gets nothing, escalate the register. This one is explicitly a formal notice: the amount outstanding, how far overdue it is, a specific date by which you require payment, and a plain statement of what happens if that date passes — suspension of further work, application of your agreed late fee, and referral for recovery. Put it in writing, keep a copy, and mean the deadline. A deadline you do not enforce teaches the client that none of your deadlines are real.

3. The letter of demand

The boundary between routine chasing and formal recovery. Covered in detail in the next section.

4. Mediation or the small business commissioner

Before spending money on lawyers, use the low-cost dispute resolution infrastructure that exists precisely for this. Covered below.

5. Debt collector or lawyer

A collection agency suits clean, undisputed debts where the client is simply avoiding you. Expect to pay a commission on recovery or a fee per matter. Check the agency's compliance with the ACCC and ASIC debt collection guideline — you are responsible for conduct undertaken in your name, and harassment exposes you, not just them.

A lawyer's letter costs more but carries more weight, and is the right choice where the debt is disputed, the contract is complex, or the amount justifies it. Many will send a formal letter of demand for a fixed fee.

6. Tribunal or court

Every state and territory has a small claims jurisdiction — a tribunal or a magistrates court division — designed for self-represented parties, with simpler procedures and a monetary limit above which you must use a higher court. Filing fees apply and vary by jurisdiction and claim size; check your tribunal or court's current fee schedule directly.

Two hard truths. A judgment is not money — it is a court's confirmation that you are owed it, and collecting is a separate enforcement process. And a limitation period applies to suing on a debt, varying by state and territory, so do not assume you have unlimited time.

7. Statutory demand (companies only)

If the debtor is a company, a statutory demand under the Corporations Act requires payment of an undisputed debt above a prescribed threshold, and failure to comply creates a presumption of insolvency that can support a winding-up application. It is powerful, and it is not a routine collection tactic.

The requirements are strict, the form and supporting material must be correct, and if the debt is genuinely disputed the company can apply to have the demand set aside, with costs against you. Using a statutory demand as pressure on a disputed debt is a well-known way to lose money. Only proceed with legal advice.

The letter of demand

A letter of demand is a formal written notice that you require payment by a stated date and will take further action if it is not made. It is usually the last cheap step before real cost, and it works surprisingly often — because it is the point at which a slow payer realises you are actually going to pursue this.

A good letter of demand contains:

• The full legal name of the debtor entity and your own
• What the debt is for — the contract or job, the date, and the work performed
• The exact amount outstanding and the invoice numbers making it up
• A short history: when the invoice was issued, when it fell due, what reminders you sent
• Any interest or late fee claimed under your agreed terms
• A clear deadline for payment and exact payment instructions
• A plain statement of what you will do if the deadline passes
• A copy of the invoice and, where useful, the accepted quote

Tone matters more than people expect. Firm, factual and unemotional beats aggressive. Threats you cannot or will not carry out damage your position, as does anything that reads as harassment. Never threaten action you are not prepared to take.

Send it in a way you can prove — email plus registered post is standard — and keep a copy of everything. If this reaches a tribunal, a documented, proportionate escalation trail is exactly what a decision-maker wants to see. business.gov.au publishes a free letter of demand template you can adapt.

Security of payment: read this first if you are in construction

If your business carries out construction work or supplies related goods and services, this section is worth more than everything above it.

Every Australian state and territory has security of payment legislation. It exists because the construction industry has a structural cash flow problem: money flows down a contractual chain, and everyone below the top is exposed to the delays of everyone above them. The legislation creates a statutory right to progress payments and, crucially, a rapid adjudication process that sits outside the courts.

The mechanics differ by jurisdiction, but the shape is consistent. You serve a payment claim — a statutory document, not simply an invoice, although in several jurisdictions a correctly prepared invoice can serve as one. The respondent must reply with a payment schedule stating what they propose to pay and why, within a defined period. If they do not respond, or they schedule less than claimed and do not pay, you can refer the matter to an adjudicator, who makes a binding determination enforceable as a judgment debt.

Why this matters:

• It is dramatically faster than court — determinations come in weeks, not months or years
• It is dramatically cheaper, and designed to be usable without a lawyer in simpler matters
• The determination binds on an interim basis, so you get paid now and any final dispute is resolved later
• A respondent who fails to serve a payment schedule in time can lose the right to raise reasons for withholding payment at all

And why it goes wrong: the deadlines are short and unforgiving, and they differ between states and territories. Every stage — serving the claim, the reference date it relates to, responding to a payment schedule, applying for adjudication — is time-limited. Miss a deadline and you can forfeit the right to use the regime for that claim entirely, no matter how obviously you are owed the money. There is generally no discretion to excuse a late step because you were busy on site.

Because the regimes and their timing differ by jurisdiction, this guide deliberately does not state any timeframes. The correct action is:

1. Identify which state or territory's legislation applies to your contract
2. Contact your state or territory building authority or building commission for their published security of payment guidance, or speak to a construction lawyer
3. Do it now — before there is a dispute, so you already know your process — and immediately if a payment is already in trouble

Set your payment claim process up once, template it, and use it as standard practice rather than as an emergency measure. Contractors who serve compliant payment claims routinely get paid faster than those who send ordinary invoices, before any adjudication is ever needed.

Mediation before litigation

Australia has genuinely useful, low-cost dispute resolution for small business, and it is under-used.

The Australian Small Business and Family Enterprise Ombudsman (ASBFEO) assists small businesses with disputes, including payment disputes with larger businesses and with government. ASBFEO can help you understand your options and refer or assist you into low-cost alternative dispute resolution, and it has a specific focus on payment times.

State and territory small business commissioners — operating under various names across the jurisdictions — offer mediation for commercial disputes at fees far below litigation, often with a substantially subsidised first session. Their resolution rates are high, largely because a mediated conversation surfaces the actual blockage: a disputed variation, a quality complaint nobody told you about, or a client with their own cash flow crisis who would happily agree to a payment plan if asked.

Mediation is also the right move when you want to keep the client. A tribunal claim ends the relationship; a mediated payment plan often does not. Two practical notes: mediation only works if both parties turn up, so it is not the answer where the other side refuses to engage at all; and any payment plan agreed should be documented in writing, with the consequence of default spelled out.

When to write it off

Not every debt is worth chasing, and pretending otherwise costs more than the debt.

Do the arithmetic honestly. Your time has a value — hours spent chasing are hours not spent quoting or working. Add filing fees, collection commission or legal costs, then multiply by your realistic chance of recovering anything. A small debt owed by a company that has stopped trading is usually worth nothing regardless of how right you are.

Signs it is time to stop: the debtor entity has been deregistered or is in liquidation or bankruptcy; the amount is below the point where fees and your time exceed it; the debt is genuinely disputed and your paperwork is weak; or you cannot identify or locate the actual legal entity.

Writing off is not the same as forgetting it. Two things should follow.

Recover the GST if you can. If you account for GST on a non-cash (accruals) basis, you remitted GST when you issued the invoice — so you have already paid tax on money you never received. The ATO permits a decreasing adjustment where a debt is written off as bad, or where it has been overdue for a set period, subject to conditions. On a cash basis this does not arise, because you only remit GST on what you actually receive.

Claim the bad debt deduction if you are eligible. A debt genuinely written off as bad may be deductible for income tax, generally where the amount was previously included in your assessable income and the write-off happens before the end of the income year. "Genuinely written off" means a real decision recorded in your books, not an invoice you gave up on mentally.

Both have specific conditions and timing rules, and both get done wrong regularly. Give the list to your accountant and let them handle the treatment.

Then do the most important thing: work out which upstream control would have prevented it. No deposit? Terms never agreed in writing? Wrong entity on the contract? No progress claims on a long job? Every bad debt is tuition, and it is only worth the money if you change something.

Frequently asked questions

Can I charge interest on late payments? Generally only if your contract, quote or terms of trade said so before the work started — you cannot invent a late fee after the invoice goes unpaid. The clause must be clearly disclosed rather than buried, and a rate a court would see as a penalty rather than a genuine cost can be unenforceable. Have your terms drafted or reviewed once, then reuse them. A modest, clearly stated late fee usually changes behaviour more than it earns.

How long do I have to chase an unpaid invoice? A legal limitation period applies to suing on a debt, it varies by state and territory, and once it expires the debt is generally unrecoverable in court. Do not treat it as breathing room — evidence goes stale, people move on, and companies get deregistered long before the clock runs out. If an invoice is materially overdue and the client has stopped engaging, escalate within weeks, and confirm the applicable period with a lawyer.

Should I use a debt collector? For clean, undisputed debts where you have good paperwork and the client is simply avoiding you, it can be worth the commission. It is the wrong tool where the debt is genuinely disputed, where recovery would not cover the cost, or where you want to preserve the relationship. Collectors must comply with the ACCC and ASIC debt collection guideline, and how someone collects in your name reflects on you.

What makes an invoice a valid tax invoice? If you are GST-registered: the words "Tax invoice", your identity and ABN, the date of issue, a description of what was supplied including quantity where relevant, and either the GST amount or a statement that the total includes GST. Above the ATO's threshold for higher-value invoices you must also show the buyer's identity or ABN. If you are not GST-registered, issue an ordinary invoice — do not call it a tax invoice and do not show GST.

Is a payment claim under security of payment legislation different to an invoice? Yes, and in construction the difference is decisive. A statutory payment claim triggers a formal response obligation and a fast adjudication route far cheaper and quicker than court. Every state and territory has a regime, they differ, and the deadlines are short and unforgiving — missing one can forfeit the right for that claim. Contact your state building authority or a construction lawyer immediately.

Can I get back the GST I already paid on an invoice that was never paid? If you account on an accruals basis you remitted GST when the invoice was issued, so an unpaid invoice leaves you out of pocket. The ATO allows an adjustment where the debt is written off as bad or has been overdue for a set period, subject to conditions, and there may also be an income tax deduction for a bad debt genuinely written off before year end. The rules are specific — have your accountant do it properly.

This guide is general information only and is not legal, financial or tax advice. It does not take account of your particular circumstances, contracts or jurisdiction. Debt recovery, security of payment and tax outcomes depend heavily on the specific facts, your contract terms and the state or territory whose law applies. Before acting, confirm current requirements, thresholds, fees and timeframes with the relevant authority — the ATO, your state or territory building authority, your tribunal or court, ASBFEO or your state small business commissioner — and seek advice from a qualified lawyer or registered accountant. If you are in construction and a payment is in dispute, get advice immediately: security of payment deadlines are short and cannot generally be extended.
