DebtCallThe best debt recovery happens before the debt ever goes bad. By the time an invoice is overdue, your options are shaped almost entirely by decisions you made at the start of the relationship – what you agreed, what you wrote down, who you agreed it with, and whether your terms will actually hold up. Businesses that recover debts reliably tend to have unglamorous but solid foundations. Here's how to build them.
Put it in writing, and get it signed
A written, signed agreement is the bedrock of recovery. It fixes what was agreed so you can prove it later, and it removes the "that's not what we agreed" defence that derails so many debt claims. This doesn't require a fifty-page contract – clear terms of trade, accepted in writing before you supply, are enough for most small businesses. The key is that the customer has genuinely agreed to your terms up front, not seen them for the first time on the invoice.
Does clicking "I agree" count?
For businesses that sign customers up online, a click can be just as binding as a handwritten signature. Australia's electronic transactions laws give electronic acceptance and electronic signatures the same legal standing as ink on paper, so a customer who ticks "I agree to the Terms & Conditions" can form a fully enforceable contract – and courts have held customers to online terms accepted this way even when they never actually read them.
That only holds, though, if the click is set up properly, and this is where a lot of online terms fall down. To give a click-accept real value: present your terms, or a clear link to them, right at the point of acceptance and before the customer commits – not tucked away in a footer. Require a deliberate, active step – an unticked box the customer has to tick, or an "I agree" button they have to press – never a pre-ticked box or a vague "by using this site you agree." Make it plain that clicking forms a binding contract. And keep a record of each acceptance: who agreed, when, from what device or IP address, and exactly which version of your terms they saw. If the debt is ever disputed, that record is your proof the contract exists. A passive "browsewrap" set-up, where terms are merely linked and you treat continued use as agreement, is weak and often unenforceable; an active, well-recorded click-accept is strong.
One important exception: don't let a personal guarantee ride on the same click. Because a guarantee must be signed by the guarantor personally, relying on a general "I agree to the T&Cs" tick to bind a director to a guarantee is risky – courts have refused to enforce guarantees where the individual didn't clearly and personally sign. Capture any guarantee as its own specific, separately signed step, clearly tied to the named individual.
The clauses that make recovery easier
A few specific terms do a lot of the heavy lifting when it comes time to collect.
Set clear payment terms – an unambiguous due date so there's no argument about when payment is late and the clock starts. Include a right to charge interest on overdue amounts, which compensates you for the delay and gives slow payers a reason to prioritise you. Add a clause allowing you to recover reasonable collection and legal costs, so chasing the debt doesn't come entirely out of your margin.
If you supply goods, a retention of title clause lets you keep ownership until you've been paid in full, so you can reclaim unpaid stock rather than joining the queue of unsecured creditors. That protection is far stronger if you register your interest on the Personal Property Securities Register (PPSR) – registering turns it into a secured interest with priority, whereas failing to register can leave you as an unsecured creditor recovering little if the customer goes under. Registering is more accessible than it sounds: it's an online, self-service process on the PPSR website, a standard registration costs only a few dollars (well under $10) and can last up to seven years, and it takes effect almost immediately once lodged. For a straightforward retention-of-title interest you can usually do it yourself – just get the details right, because an incorrectly registered interest can be ineffective, so complex or high-value arrangements are worth a professional review.
Take a personal guarantee – and execute it properly
When your customer is a company, one clause matters more than almost any other: the personal guarantee. Because of limited liability, a company's debt belongs to the company, not to the director who ordered the goods – so if the company can't pay, you may be left with a claim against an empty shell. A personal guarantee fixes that. It's a promise by a director or owner to be personally liable if the company defaults, converting the debt into a claim you can also bring against a real individual with a house, a car and savings. For that reason, a guarantee is only ever as good as the guarantor's own assets – so it's worth knowing who you're dealing with.
A guarantee is only worth anything if it's set up correctly, though, and this is where many creditors come unstuck.
It must be in writing and signed by the guarantor. The requirement traces back to the old Statute of Frauds and survives in state law today (Victoria's Instruments Act 1958, Queensland's Property Law Act 1974, and equivalents elsewhere). A verbal "I'll stand behind it" generally can't be enforced, and it's the guarantor who must sign.
It can't just be buried in your terms and conditions. Because the guarantor has to have genuinely agreed to that specific obligation, a guarantee tucked into fine print is easily challenged. Make it a clear, distinct, separately signed part of your credit application, signed by the director in their personal capacity – not just as a signatory for the company. Courts have refused to enforce guarantees where the signature was unauthorised, where only some intended guarantors signed, or where an electronic signature couldn't be authenticated.
Get the timing right. A guarantee needs consideration – usually your agreement to extend credit – and consideration can't be something that already happened, so the guarantee should be signed before, or at the same time as, you extend credit. The safest route is to execute it as a deed, which is binding without consideration. It's also wise to take a combined guarantee and indemnity: an indemnity is a primary obligation that can stand on its own if the guarantee ever fails on a technicality.
Finally, a guarantee has to survive a challenge in court. Australian courts will set one aside where the circumstances were unfair – as in Commercial Bank of Australia v Amadio, where elderly guarantors with limited English and no independent advice didn't understand their unlimited liability, or Garcia v National Australia Bank, which protects volunteer guarantors (classically a spouse) who don't understand the transaction. The best protection is to make sure the guarantor genuinely understood what they signed, and for anything significant, to recommend they get independent legal advice first – a guarantor who was advised and signed anyway has little room to claim later that they didn't understand.
Make sure your terms are fair – or a court may not enforce them
Here's a point many businesses miss: a term being in your contract doesn't guarantee a court will enforce it. Under the unfair contract terms regime in the Australian Consumer Law, terms in standard-form contracts with consumers and small businesses can be declared unfair and void – and since 9 November 2023, using or relying on an unfair term is prohibited and can attract civil penalties. The small-business protections are broad: they apply where a party employs fewer than 100 people or has annual turnover under $10 million, which covers most of the customers a small business deals with.
A term is "unfair" if it does three things together: it would cause a significant imbalance in the parties' rights, it isn't reasonably necessary to protect your legitimate interests, and it would cause detriment to the other party if relied on. Overreaching clauses – a right to change the price or terms unilaterally, an excessive penalty dressed up as a fee, a wildly one-sided indemnity – are exactly what the regime targets.
The practical takeaway is that fairness isn't just good ethics; it's what makes your terms enforceable. Keep them transparent (plain English, clearly presented, not hidden), proportionate, and genuinely necessary to protect your position. That applies squarely to your interest and late-fee clauses: charge them only where they were agreed before you supplied, and keep them reasonable rather than punitive – a modest, clearly disclosed rate will hold up where an extravagant penalty can be struck out. Terms your customer knowingly agreed to, and that a court sees as fair, are both more enforceable and less likely to be disputed in the first place.
Have an escalation process ready
Good contracts pair with a clear, repeatable process for when payment doesn't come. The standard ladder is: invoice, then a reminder if it's missed, then a formal letter of demand, and only then legal action as a last resort. Having this mapped out in advance means you act promptly and consistently instead of agonising over each late payer – and acting promptly, as any experienced creditor will tell you, is half the battle.
The letter of demand is the pivotal step, and it's most effective coming from a law firm. DebtCall is a law firm that issues a formal letter of demand for the Pre-Court Fee, delivered by email and SMS, with a few automated reminders and a way for the debtor to respond with a payment plan or deferral. Payment goes straight to your own account, and if a matter ever needs to go to court, DebtCall can act for you as your law firm. It's the formal step in that ladder: a serious, law-firm demand that resolves many debts on its own.
Solid contracts won't eliminate late payers entirely. But they tilt every part of the recovery process in your favour, and they turn a stressful scramble into a straightforward, well-worn path.
