Purchase order terms and conditions

In commercial law, a purchase order acts as a formal offer to buy. In the US under the Uniform Commercial Code (UCC) and in the UK under the Sale of Goods Act, a contract is formed the moment the seller acknowledges the PO or begins performance. This makes the terms and conditions printed on the PO document legally enforceable.

It is important to distinguish between a PO and an invoice. The PO is a buyer-generated document that initiates the trade, whereas an invoice is a seller-generated request for payment. When a larger master agreement exists, the PO usually acts as a 'release' under those pre-negotiated terms, but if no master agreement exists, the PO's own small print governs the entire deal.

Most PO terms focus on the logistics of the exchange. This includes precise descriptions of the goods, shipping terms (often using Incoterms like FOB or DAP), and inspection rights. Buyers usually include a clause allowing them to reject goods that do not meet quality standards within a specific timeframe after delivery.

Payment terms are another cornerstone. These define when the clock starts ticking for payment - usually upon receipt of a valid invoice or acceptance of goods. In the EU, Late Payment Regulations may override PO terms if the stated payment period is deemed unfair to the supplier, typically capping standard terms at 60 days unless otherwise agreed.

• Product specifications and quantity
• Price and currency of transaction
• Delivery dates and shipping methods
• Inspection and rejection rights
• Payment timelines (e.g., Net 30)
• Warranty for defects
• Compliance with local labor and environmental laws

A common legal conflict known as the 'battle of the forms' occurs when a buyer sends a PO with their terms, and the seller responds with an acknowledgement containing their own different terms. In many jurisdictions, the 'last shot' rule applies, meaning the last document sent before performance begins may dictate the contract terms.

To avoid this uncertainty, sophisticated businesses include a 'precedence' clause. This states that the terms of the PO override any conflicting terms found in the seller's documentation. Without this, a dispute over a late delivery or broken product could end up in a legal grey area where it is unclear which party's liability limits apply.

Unlike long-term contracts, POs often have specific language regarding cancellation. A buyer may seek the right to cancel a PO 'for convenience' before the seller has begun custom manufacturing. However, if the goods are bespoke, the seller will usually insist on a clause requiring the buyer to pay for raw materials and labor incurred up to the point of cancellation.

Termination for cause is also standard. This allows either party to void the order if the other party goes bankrupt or fails to deliver on time. In India and the UK, these clauses must be drafted carefully to ensure they do not act as an unenforceable penalty, but rather a genuine pre-estimate of loss.

• Notice period for cancellation
• Liability for work-in-progress costs
• Termination for material breach
• Force majeure events affecting delivery
• Return procedures for cancelled orders

Every PO should specify the governing law. For international transactions, this determines which country's courts will resolve a dispute. Many international POs also reference the United Nations Convention on Contracts for the International Sale of Goods (CISG), which provides a default set of rules unless explicitly excluded.

Compliance clauses are increasingly vital. These require the seller to certify they are not using forced labor, are not on any sanctions lists, and are complying with data protection laws like the GDPR if the order involves processing personal information. Failure to include these can expose the buyer to significant regulatory fines.
