How to recover an unpaid debt when cash is tight

Why tight cash flow makes recovery urgent, not impossible

A subcontractor completes a job, sends the invoice and waits. The customer does not pay. By the time the creditor is ready to act, wages, materials and tax obligations have consumed the cash that should have funded recovery. The debt remains, but the money to chase it has gone.

Construction businesses often run tight. One late payment can force you to dip into reserves to cover the next job, leaving nothing for debt recovery. This is exactly when some debtors expect you to give up.

Limited cash does not remove your options. It makes the order and cost of each step critical. Some of the most effective early actions cost almost nothing. Others require careful assessment of the debt size, evidence and the debtor's position.

Gather and organise your evidence first

Start by collecting every document that supports your claim. Pull together your contract, quote, invoices, delivery records, site notes, emails and text messages where the debtor agreed to the work or the price. This step costs nothing and forms the foundation of every action that follows.

Without clear evidence, you cannot assess whether you have a strong claim, what process applies or whether the debt is worth pursuing. A formal demand, a court application or an adjudication submission all depend on the records you hold now.

Organise the material by date. Confirm the amount owed, what work was completed, when payment was due and what follow-up has occurred. This preparation saves time and cost later, and often reveals gaps or disputes you need to address before escalating.

Send a formal written demand yourself

A clear written letter demanding payment by a specific deadline is one of the lowest-cost steps available. You can prepare it yourself. State the amount owed, refer to the invoice and contract, set a deadline of seven to fourteen days, and explain that further steps will follow if the debt remains unpaid.

Many debts are paid at this stage because the demand signals you are serious. The letter does not need to be complex, but it must be factual, professional and specific about the consequences of non-payment.

Keep a copy of the letter and proof of delivery. If you later need to take formal action, this demand forms part of your evidence. Do not threaten steps you are not prepared to take or cannot legally pursue.

Understand your state's security of payment process

Before spending money on a lawyer or debt collector, confirm whether security of payment legislation applies to your contract. These laws provide a relatively fast process to recover progress payments due under construction contracts.

Each state and territory has its own security of payment legislation with specific rules about timing, payment claims, payment schedules and adjudication. The process is designed to be accessible without legal representation, though the steps must be followed precisely.

If your contract is for construction work, check whether you are within the timeframes to serve a payment claim, whether the debtor has provided a payment schedule, and what your next available step is. Mistakes in timing or form can close off this pathway, so verify the requirements for your state before acting.

Match recovery cost to debt size and strength

A small undisputed debt may be better suited to a tribunal or small claims process, which typically has lower fees and simplified procedures. A larger debt or one involving a contract dispute may justify more formal legal steps or adjudication.

Consider the debtor's financial position. If the debtor is still trading and solvent, recovery may be straightforward. If the debtor has entered administration or liquidation, the process changes and the likelihood of full recovery usually falls.

Do not spend more on recovery than you can realistically expect to collect. Assess the evidence, the debtor's capacity to pay, and the cost of each available option before committing to a course of action.

Seek advice early, before options narrow

Many construction businesses wait until a debt is months old before seeking help. By then, the debtor may have moved, restructured or spent available cash. Limitation periods, adjudication deadlines and other time-sensitive rights can expire while you wait.

A short conversation with a specialist can clarify which process applies, what evidence you need and what realistic recovery options remain. This advice often costs less than continuing ineffective follow-up or missing a critical deadline.

If you are uncertain whether to act yourself, use a collection agency or engage a recovery specialist, ask. The cost of choosing the wrong path or delaying action is usually higher than the cost of early advice.

Understand limitation periods and the cost of delay

Time limits for commencing legal action vary by state and territory. For most debts arising from a contract, the limitation period is usually six years from when the debt became due, though it is three years in the Northern Territory. Payments or written acknowledgements of the debt can restart the period in some jurisdictions.

Do not assume you have six years from the date you last followed up. The limitation period usually runs from when the debt became payable or was last acknowledged in writing. Obtain legal advice if you are unsure whether your claim is within time.

Delay also affects your practical recovery prospects. The longer you wait, the harder it becomes to locate the debtor, verify their solvency and recover money that may already have been spent. Early action preserves more options.
