An Australian Vendor Agreement — also known as a Supplier Agreement or Supplier Terms — is a legally binding commercial contract between a vendor (the seller or supplier of goods) and a buyer (the business or individual purchasing those goods) that establishes the terms and conditions governing an ongoing supply relationship. Unlike a one-off purchase order, a vendor agreement creates a framework that applies to each successive order placed under it, ensuring consistency of commercial terms and providing both parties with certainty and legal protection over the course of the supply relationship.

Vendor agreements in Australia are subject to the Australian Consumer Law (ACL), which is Schedule 2 of the Competition and Consumer Act 2010 (Cth). The ACL implies mandatory statutory guarantees into every contract for the supply of goods to a consumer — including a guarantee of acceptable quality (s 54), fitness for disclosed purpose (s 55), correspondence with description (s 56), and compliance with express warranties (s 59). These guarantees cannot be excluded, restricted, or modified by contract. Where the buyer is a business (not a consumer), greater contractual freedom exists, but the ACL's unfair contract terms provisions apply to standard form contracts where the buyer is a small business (employing fewer than 100 persons or with annual turnover under $10 million).

GST is a critical consideration in every Australian vendor agreement. Under the A New Tax System (Goods and Services Tax) Act 1999 (Cth), most supplies of goods by a GST-registered entity attract GST at 10%. The agreement must clearly state whether prices are inclusive or exclusive of GST, and must require the vendor to issue valid tax invoices with the vendor's ABN and the GST amount specified. Failure to address GST expressly in the agreement is a frequent source of commercial disputes.

Title and risk in goods are separate concepts that a vendor agreement must address. Risk (the risk of loss or damage to the goods) typically passes on delivery. Title (legal ownership) typically passes on payment in full — a retention of title arrangement that, under the Personal Property Securities Act 2009 (Cth) (PPSA), must be registered on the Personal Property Securities Register (PPSR) to be effective against third parties including the buyer's creditors or liquidator in the event of insolvency.

The Australian Competition and Consumer Commission (ACCC) enforces the ACL and the Competition and Consumer Act 2010 (Cth), including prohibitions on misleading and deceptive conduct (s 18 ACL), unconscionable conduct (ss 20-22 ACL), and anti-competitive conduct (Part IV CCA). Vendor agreements must not contain terms that require minimum resale prices (resale price maintenance is generally prohibited) or that create absolute territorial restrictions on the buyer's right to resell the goods.

A written Vendor Agreement is essential for any business that regularly purchases goods from a supplier or vendor, or that supplies goods to other businesses on an ongoing basis. Without a written agreement, the terms of supply are determined by purchase orders, emails, and the common law — a situation that frequently leads to disputes about price, delivery, returns, and liability.

Retailers and distributors that purchase inventory from domestic or overseas vendors should have a vendor agreement that defines the product range, wholesale pricing, minimum order quantities, lead times, delivery terms, and the vendor's obligations regarding product quality and ACL compliance. Retailers face significant exposure if they sell goods that do not comply with the ACL's acceptable quality guarantee — and their recourse against the vendor depends on having clear contractual protections in place.

Manufacturers, importers, and wholesalers that supply products to retail chains, e-commerce platforms, or corporate buyers should ensure they have signed vendor agreements that specify their liability, their warranty obligations, the pricing and GST treatment of each product, and the buyer's rights on return of defective goods. Without a written agreement, the buyer's purchase orders may incorporate unfavourable standard terms by reference, and the vendor may find itself bound by terms it never agreed to.

Businesses that supply goods under a private label or white-label arrangement — where the buyer rebrands the vendor's products for resale — need a vendor agreement that addresses intellectual property in packaging and labelling, the vendor's responsibility for product safety compliance, and the treatment of product recalls. Under the ACL, a business that engages in 'trade and commerce' may be liable for misleading representations about goods regardless of whether it is the manufacturer.

Online marketplaces and e-commerce platforms that onboard product vendors need standard vendor terms that govern listing quality, pricing, fulfilment obligations, returns, and the treatment of consumer complaints. The platform's vendor terms must be consistent with the ACL's consumer guarantee regime to ensure that buyers have access to the remedies to which they are legally entitled.

A comprehensive Australian Vendor Agreement should include the following key provisions to achieve effective legal protection, commercial certainty, and ACL compliance.

Identification of Parties — Identify each party by its full legal name and ABN. For companies, include the ACN. The ABN is required for valid tax invoices under the GST Act, and confirming the other party's ABN at the outset reduces the risk of transacting with an unregistered entity.

Product Range and Pricing — Define the products covered by the agreement, either by description or by reference to a current catalogue or price list. Specify the pricing mechanism — whether prices are from a wholesale price list (updated with notice), fixed per order, or on a cost-plus basis. Include a mechanism for price adjustments, with an appropriate notice period to allow the buyer to plan purchasing. Clearly state whether prices are inclusive or exclusive of GST.

Purchase Order Process — Define how purchase orders must be placed (email, online portal, written form), what a purchase order must contain (products, quantities, delivery date), and when a purchase order becomes binding (on the vendor's written acceptance). Include a 'battle of the forms' provision stating that the vendor's terms prevail over any inconsistent terms on the buyer's purchase order.

Delivery Terms — Specify the delivery method (DDP, Ex Works, freight at cost), the standard lead time, the consequences of late delivery, the procedure for inspecting goods on receipt, and the time limit for reporting damage or discrepancy. Specify when risk and title pass.

Payment Terms and GST — State the payment terms (days from invoice, method of payment), any early payment discount, the procedure for disputed invoices, and the consequences of late payment (interest, suspension of supply, lien over goods). Include a clear GST clause requiring valid tax invoices and specifying the GST treatment of all supplies.

Returns, Defects, and ACL Compliance — Acknowledge the ACL's statutory guarantees and specify the procedure for returning defective goods (notification period, RMA process, remedies). Include a workmanship and materials warranty. Address change of mind returns separately — these are not required by the ACL for business-to-business transactions but may be commercially appropriate.

Title Retention and PPSA — Consider including a retention of title clause and, if included, register a purchase money security interest (PMSI) on the PPSR within 15 business days of the buyer obtaining possession of inventory to protect the vendor's priority in the event of the buyer's insolvency.

Term and Termination — Specify the duration of the agreement (ongoing or fixed term), the notice period for termination for convenience, the grounds for immediate termination on cause (material breach, insolvency), and the consequences of termination for outstanding orders.
