Short answer: for an undisputed B2B debt under $10k, send a $29 lawyer-letterhead letter first. For $1k–$50k portfolios with multiple debtors, hand it to a debt collection agency on commission. For company debtors owing $4k+ and ignoring you, consider a statutory demand. For disputed or large-dollar matters, engage a solicitor before any letter goes out.

The four standard routes — side by side

Most Australian creditors evaluating their options consider four standard routes: a letter of demand, a debt collection agency, small claims court (NCAT in NSW), or a solicitor. The right route depends on debt size, dispute status, and how much of your own time you want to spend.

Factor Letter of demand Debt collection agency Small claims (NCAT / Local Court) Solicitor
Cost $29 fixed (lawyer) or free DIY 15–30% commission, no-win-no-fee common $58–$117 filing (NSW NCAT/Local) $300–$800+ per hour, or fixed fee
Speed to outcome Days 2–8 weeks 6–12 weeks (judgment); enforcement adds months 4–16+ weeks depending on complexity
Best debt size Under $10k, undisputed $1k–$50k, especially multi-debtor Under $40k NCAT / $10k–$100k Local Court $20k+ or disputed
Success rate ~55–65% if undisputed, lawyer letterhead ~35–50% net of commission ~70% if judgment obtained — enforcement is separate Variable; high if facts are strong
Effort required Low (15 minutes to instruct) Low (hand off, monthly updates) Medium (file documents, appear at hearing) Low (lawyer drives; you provide instructions)
When to use First step on any undisputed B2B debt LOD ignored, or multiple debtors at once Debtor refuses or disputes after LOD Complex facts, large amounts, counterclaim risk

The standard sequence for an undisputed B2B debt: letter of demand → wait 14 days → either receive payment (the majority outcome) or escalate. Most creditors over-think the choice; the cheap-and-fast first step is almost always a letter, with escalation chosen based on what happens after the deadline.

Five less-obvious routes most creditors miss

The four routes above are the textbook list. There are five other paths that fit specific situations, and they are routinely overlooked because they don't appear in generic "debt recovery" content.

5. Statutory demand (Corporations Act s459E) — company debtors only

If your debtor is a Pty Ltd company and the debt is at least $4,000, a statutory demand under section 459E of the Corporations Act 2001 (Cth) is one of the most powerful recovery tools available. The debtor has 21 days to pay or apply to set aside the demand; failure to do either creates a statutory presumption of insolvency, which is grounds for a winding-up application. Most companies pay rather than face that risk. Drafting a statutory demand is technical work — engage a solicitor; expect $200–$500 in fees.

6. Payment plan negotiation

If the debtor signals willingness but says cash flow is constrained, a structured payment plan often delivers more than escalation. Get the plan in writing, signed, with default clauses that revive the full amount on missed instalments. This protects the commercial relationship in cases where you want the customer to keep buying — escalation closes that door permanently.

7. Invoice factoring or discounting

Rather than chase the invoice, sell it. Factoring companies (Earlypay, Octet, ScotPac and others) buy your unpaid invoices at a discount of typically 1–4% per month outstanding, advancing 80–90% of face value within days. Useful when your real problem is cash-flow timing rather than the debtor's willingness to pay. Trade-offs to understand before choosing this route: you give up 1–4% of every invoice, the factoring company takes over the collection relationship with your customer, most facilities have $5k+ minimum invoice values and may require a portfolio commitment rather than one-off invoices, and the cost compounds against the timeline of recovery rather than capping at the LOD fee. For a single overdue invoice under $20k where the debtor is solvent and just slow, a $29 letter is dramatically cheaper. For systemic cash-flow stress across a customer book, factoring may be the right structural answer.

8. Industry ombudsman or dispute resolution

If your debtor is in a regulated industry, the relevant ombudsman or commissioner provides free dispute resolution that is faster than court. AFCA covers financial services; the TIO covers telecommunications; each state has a Small Business Commissioner (NSW SBC, VSBC in Victoria) running low-cost mediation. Useful when the matter is technically disputed but commercially solvable.

9. ATO Tax-Debt Disclosure (for company debtors $100k+, 90+ days overdue)

Under the disclosure regime in the Taxation Administration Act, the ATO can report tax debts of $100k+ that are more than 90 days overdue to credit reporting bureaus. While this is the ATO's remedy and not directly available to private creditors, it materially changes the incentive structure for company debtors with overdue ATO obligations — they may prioritise paying any creditor whose escalation would compound the credit-score impact. Knowing whether your debtor is in this position (via a credit check) informs whether escalation is likely to work.

Decision matrix — match your situation to the right move

This is the table most readers should screenshot. Each row is a real creditor situation; the right-hand column is the best first move based on cost, speed, and recovery probability.

Your situation Best first move
Owed under $10k, undisputed B2B invoice, want it resolved fast and cheap Letter of demand on lawyer letterhead ($29)
Owed $1k–$50k across multiple debtors, you don't want to manage it Debt collection agency on no-win-no-fee commission
Debtor disputes the amount, the quality of work, or the contract terms Solicitor before any letter — fix the dispute first
Debtor is a Pty Ltd company, owes $4k+, and is ignoring you Letter of demand first; if ignored, statutory demand under s459E
Debtor has offered a partial payment or asked for time Written payment plan with default clauses — not escalation
You need cash now and can accept a haircut Invoice factoring (1–4%) — but check the trade-offs above
Debt is over 5 years old in NSW Check the limitation period before doing anything — see statute of limitations on debt in NSW
Debtor already in liquidation or voluntary administration Lodge a proof of debt with the external administrator — no letter needed
Owed by a consumer (B2C), not a business NCAT or your state tribunal (cheap, fast); SydneyCollect handles B2B only
If you're in the most common case — an undisputed B2B debt under $10k — the cheap-and-fast first move is a $29 lawyer-letterhead letter. About 55–65% of these resolve at the letter stage. The 35–45% that don't, escalate from there. Send a letter — $29

Why a letter of demand is almost always the right first move

Three reasons the letter sits at the top of the funnel for almost every B2B debt:

  • It's diagnostic. A debtor's response to a letter tells you which of the four standard routes to take next. Pay = done. Dispute = solicitor. Silence = agency or court. Offer = payment plan. Without the letter you don't have the diagnostic signal.
  • It's evidence. NCAT, the Local Court, and most other forums expect a prior demand. Without one, your case is procedurally weaker and the magistrate or member is more likely to refer the parties back to negotiation.
  • The economics are asymmetric. $29 in exchange for a ~60% chance of resolving an unpaid invoice in days is the highest expected-value action in the entire debt recovery sequence. Even if it doesn't work, it costs less than 15 minutes of solicitor time.

The exceptions where you would skip the letter and go straight to another route are narrow: the debtor is already in formal insolvency, the limitation period is about to expire, or the dispute is so technical that any letter would be premature without legal advice first. In every other scenario, the letter is the cheapest diagnostic test available.

What happens after each route

The downstream consequences also differ, and they matter for choosing which route to take in the first place:

  • After a letter of demand: the debtor pays, disputes, offers a plan, or goes silent. The relationship is mostly preserved if they pay; mostly damaged otherwise. If they ignore the letter →
  • After a debt collection agency: 15–30% commission comes off the recovered amount. Customer relationship is functionally ended. Agencies escalate to credit reporting and small-claims filing if their internal calls fail.
  • After NCAT or Local Court: you get a judgment, which is itself only paper. Enforcement (garnishee, examination, writ of execution) is a separate step and a separate cost. Detailed LOD vs court comparison →
  • After a statutory demand: the company either pays within 21 days or faces a winding-up application. This is a high-pressure tool; expect it to either resolve the debt fast or trigger insolvency proceedings.
  • After a solicitor: you incur ongoing costs but offload almost all of the work. Suitable for matters where the recovery amount justifies the hourly rate.

Frequently asked questions

Does a letter of demand actually work?
Yes, more often than people expect. Industry data puts first-letter recovery on undisputed B2B debts at around 55–65% when the letter is sent on lawyer letterhead. The recovery rate is materially lower (closer to 25–35%) when sent by the creditor under their own name. The single biggest variable is debtor disputation: if the amount is genuinely disputed, no letter resolves it.
What happens if the debtor ignores the letter of demand?
Roughly 35–45% of debtors don't respond. The next move depends on debt size: under $10k go to NCAT (NSW) or your state tribunal — cheap and fast; $1k–$50k consider a debt collection agency on no-win-no-fee commission; over $20k or disputed, engage a solicitor or consider a statutory demand if the debtor is a company. The original letter becomes evidence in all three paths. See what to do if your letter is ignored.
Do I need a lawyer to send a letter of demand in Australia?
No — anyone can send one. But a letter on a registered legal practice's letterhead has a materially higher response rate than one sent by the creditor under their own name. Fixed-price lawyer letters start at $29 (SydneyCollect) and go up to $450+ for partner-drafted letters at large firms. See our comparison of letter of demand providers.
Can I use a letter of demand and a debt collector at the same time?
Yes — and most experienced creditors do them in sequence rather than parallel. The letter goes first ($29, days). If ignored after 14 days, the matter is handed to a debt collection agency (15–30% commission, weeks). Running them in parallel confuses the debtor and undermines both steps.
What is the success rate of letters of demand in Australia?
Industry data converges on 55–65% recovery for first letters sent on lawyer letterhead for undisputed B2B debts under $10k. Recovery falls sharply with debt size, debtor disputation, debtor solvency stress, and time elapsed since the original invoice. Recovery is roughly halved when the letter is sent by the creditor under their own name. See debt recovery rates in Australia.
When should I skip the letter and go straight to court?
Rarely. Most Australian courts require evidence of a prior demand before judgment, and the letter is cheap insurance against the debtor later claiming they were never notified. The two exceptions: (1) the debtor is already in formal insolvency — go to the administrator's queue; (2) the limitation period is about to expire (6 years in NSW) — file first, send the letter alongside the claim.
