Key Takeaways
A first purchase agreement usually goes wrong in a predictable way. It is not that the document is too short. It is that the clauses which matter are written in a form that cannot be enforced: a specification described in adjectives, acceptance criteria nobody defined until the goods existed, a change-control obligation that was never mentioned, and a delivery date without a defined start.
What follows is a checklist of subjects rather than a legal template. Contract law, jurisdiction and enforceability depend on your circumstances and the counterparty, and a qualified lawyer should review anything you intend to rely on. The purpose here is to make sure the right subjects are on the table before the first order, rather than after the first problem.
Specification: make it measurable
The specification should reference the approved sample by identifier and version, and express every characteristic that matters in a measurable form — dimension with tolerance, material grade, surface finish, performance threshold. Where a characteristic can only be described subjectively, say who decides and on what basis.
The most common failure is a specification that describes intent rather than acceptance. Both parties can agree that a product should look premium and still disagree completely about whether it does.
Acceptance: define the test, not the intention
- The inspection standard and sampling level, and whether it references a recognised scheme.
- Defect classification — what is critical, major and minor — and the consequence of each.
- Who inspects, at whose cost, and at which stage; the reasoning is in inspection timing.
- What happens when a batch fails: rework, replacement, rejection, and who bears the cost of each.
- The reference sample’s status — sealed, retained, and by whom.
Change control: usually the highest-value clause
Any change to component, material, sub-supplier, process or tooling should require written notice and your written approval before it is implemented. This single clause addresses the most common way a compliant first order becomes a non-compliant second one — a substitution nobody mentioned. The mechanics are covered in the change control guide.
Worth adding: a defined list of critical processes that may not move at all without approval, and the right to inspect at a subcontracted step where one exists.
Schedule: define the start, not just the end
A delivery date is only meaningful if everyone agrees when the clock starts. Specify what triggers the lead time — deposit received, artwork approved, pre-production sample signed off — and what happens to the date when a party causes a delay. Without a defined start, every delay is arguable.
Payment: tie money to verifiable events
A structure that releases the balance against a verifiable event, such as a passed pre-shipment inspection or a complete document set, gives you leverage at the moment it matters. The comparison of structures and terms is in payment terms and incoterms, and the execution-security side in payment security.
Warranty: define the basis, not a number
Rather than arguing over a fixed period, define how the warranty period is determined, what it covers, what it excludes, and how a claim is made. A warranty that names a period but not a remedy is not worth much; one that defines the remedy and the evidence required is worth more than a longer period with no mechanism beneath it.
Claims: window, evidence and remedy
- How soon after delivery a claim must be raised, and in what form.
- What evidence is required — photographs, batch codes, retained samples, inspection records.
- The remedy options and the order in which they apply.
- Who bears return freight, and who bears the cost of inspection to establish cause.
IP and confidentiality
If you are supplying artwork, tooling designs, packaging files or product designs, state who owns them and what happens to them if the relationship ends. Tooling ownership is a specific point worth settling explicitly — see OEM tooling cost — and confidentiality obligations are covered in our IP and NDA page.
Dispute resolution: decide before you need it
Agree the forum and the seat in advance: arbitration or litigation, in which jurisdiction, under which rules, and in which language. A clause that leaves this open is effectively a clause that guarantees the dispute will be about the forum rather than the product. This is a subject to settle with legal advice, because enforceability varies enormously.
What to leave out
- Blanket prohibitions that cannot be monitored, such as a total ban on subcontracting — usually better replaced by named critical processes and a notification obligation.
- Promises neither party can control, such as a guarantee of zero defects.
- Terms copied from another industry without adapting the acceptance and inspection sections.
- A schedule expressed only as a number of days with no defined trigger.
How ApplianceChain helps
We are not lawyers and we do not draft or review contracts for legal effect. What we can do is make sure the technical content of the agreement is complete and checkable: the specification against the approved sample, the acceptance criteria against the inspection plan, the critical-process list against what actually happens on the floor, and the delivery trigger against the production schedule.
The commercial and legal terms belong with you and your adviser. The clauses that fail most often, however, fail because the technical facts behind them were never settled — and that part we can help with.
