Can a supplier hold back new goods for an old invoice?

Start with the contract

When a supplier will not release fresh goods until you pay an older invoice, treat it as a contract problem first, not just a pressure tactic. Business.gov.au says payment terms form part of the sales contract, so your purchase order, terms of trade and later emails matter. If the papers are unclear, that is itself a warning sign. ([business.gov.au](https://business.gov.au/finance/payments-and-invoicing/payment-terms?utm_source=openai))

Check whether the contract says supply can be paused, whether set-off is allowed, and whether the supplier can link one order to another. You are looking for the exact wording, not a vague business understanding. If the contract is silent, the supplier may be relying on leverage rather than a clear contractual right.

Ask for the reason in writing

Ask the supplier to put its position in writing before you pay anything else. Request the clause it relies on, the invoice it says is overdue, the goods being withheld and the reason those goods are tied to the old debt. Business.gov.au encourages written records when a payment dispute starts.

Keep the reply short and factual. Ask for the basis in plain language and save every email, text and delivery note. If the supplier later changes its story, you will have a timeline. That record matters because disputes often turn on what was said, when it was said and who said it.

Keep the old debt separate

Do not let the old invoice swallow the current supply issue. If the debt is genuine, negotiate it separately and decide whether part payment, a date for payment or a short standstill will move the goods. Separating the two issues keeps the conversation commercial and stops one overdue account from freezing every future delivery.

That does not mean you accept the supplier's position. It means you avoid giving up leverage on the new order while the old account is discussed. If the contract does not clearly allow the hold, ask for the goods to be released under the existing terms and keep the debt discussion in a separate channel.

Check for security wording

Also check whether the supplier is relying on any security wording, especially retention of title or another clause that says ownership or possession changes only after payment. The Personal Property Securities Act treats a security interest as an interest that secures payment or performance, and it includes conditional sale arrangements and retention of title language. ([legislation.gov.au](https://www.legislation.gov.au/C2009A00130/2024-10-14/2024-10-14/text/original/epub/OEBPS/document_1/document_1.html?utm_source=openai))

A security clause does not end the inquiry. You still need to check whether it actually covers the goods being held and whether the supplier has preserved any rights it wants to rely on. If the wording is broad, old or copied from another contract, get it reviewed before you concede that the hold is lawful. ([legislation.gov.au](https://www.legislation.gov.au/C2009A00130/2024-10-14/2024-10-14/text/original/epub/OEBPS/document_1/document_1.html?utm_source=openai))

Decide your next move

Once the paperwork is gathered, decide your next move with advice, not guesswork. A construction dispute can quickly become a supply delay, a cash flow issue and a relationship problem at the same time. That is usually the point where a practical outsider can test the contract language and help separate what is owed from what is merely threatened.

If your goods are still being held, bring the contract, the written refusal and the invoice trail together and contact CRP today about dispute resolution. CRP coordinates independent qualified professionals and can help you organise the facts, test the supplier's written basis and choose a sensible next step.
