Every business runs on suppliers, and every one of those relationships needs a contract that does more than state a price. The gaps show up during a dispute, when a batch arrives off-spec and there is no agreed standard to point at — so the argument becomes about what "defective" means rather than about the goods.
A vendor agreement should define the goods and specifications, pricing and payment, delivery timelines and acceptance, quality standards and warranties, liability and indemnity, and dispute resolution — with GST handling and compliance obligations alongside.
The bottom line
The clause that prevents most disputes: a specification sheet, plus an inspection and rejection process with a defined window.
The clause buyers forget: GST and invoicing terms, because a wrong invoice costs the buyer its input tax credit.
The clause vendors forget: a price revision mechanism, without which a long fixed-price term becomes a loss when input costs move.
What the agreement does
It governs the supply of goods or services from a vendor to a buyer over a period: the standards the vendor must meet, the buyer's payment obligations, and the consequences of failure on either side — late delivery, defective goods, non-payment.
Done well it turns a recurring commercial relationship into a predictable one, which matters more than it sounds when the supply is on the critical path of your own production.
The essential clauses
- Scope of supply — exactly what goods or services, in what quantity.
- Specifications and quality standards — the specs the supply must meet.
- Pricing — unit prices, a price revision mechanism, and whether prices are fixed for the term.
- Payment terms — schedule, invoicing, credit period, late payment interest, and GST treatment.
- Delivery — timelines, place, mode, risk and title transfer, and the acceptance or rejection process.
- Warranties — that goods are fit for purpose and free of defects.
- Liability and indemnity — for defective supply, delays and third-party claims.
- Confidentiality and IP — protecting shared information and any IP involved.
- Term and termination — duration, renewal, termination for cause and convenience, and exit obligations.
- Compliance — anti-bribery, applicable laws, and required licences such as FSSAI for food.
- Dispute resolution and governing law.
- Force majeure and insurance where relevant.
Specifications and quality
Vague quality terms are where supply disputes live.
Attach a clear specification sheet or reference standard, and define what counts as conforming and what counts as defective. Spell out inspection rights, the warranty period, and the remedy for non-conforming goods — repair, replacement, refund or rejection.
Where the supply must meet regulatory standards, whether food safety, electrical or environmental, require the vendor to hold and maintain the relevant licences and certifications as a contractual obligation rather than an assumption.
Delivery, acceptance and rejection
State the delivery timeline, and whether time is of the essence, which strengthens your remedy for delay considerably.
Define the place and mode of delivery, when risk and title pass to the buyer, and the acceptance process — how long the buyer has to inspect and reject non-conforming goods.
A clear rejection mechanism prevents the standoff every supply chain eventually produces, where the buyer says the goods were defective and the vendor says they were accepted. With a defined window, that argument has an answer.
Payment, taxes and pricing
Define the price, any price revision formula so that a change in input costs does not become a mid-term dispute, the payment schedule and credit period, late payment interest, and how GST is charged and documented.
The invoicing detail matters more than it looks: a correct invoice is what lets the buyer claim input tax credit, and a wrong one turns a tax benefit into a cost.
Where the vendor supplies on credit, consider security — an advance, a bank guarantee, or a personal guarantee.
Liability when things go wrong
Allocate risk for the things that actually fail: defective supply, with the vendor's liability and the buyer's remedies; late delivery, with liquidated damages or a delay penalty where reasonable; recall of faulty products; and third-party claims through an indemnity.
Cap overall liability where appropriate, and keep core supply failures inside the vendor's responsibility. A cap that excuses the vendor from the thing they were engaged to get right leaves the buyer with an agreement that does not protect them where it counts.
A worked example
A packaged food company contracts a supplier for an ingredient.
The agreement attaches a specification sheet and requires the supplier to hold a valid FSSAI licence. Unit price is fixed for six months with a defined revision mechanism after that. Payment is net 30 with correct GST invoicing. Time is of the essence for delivery, with a delay penalty. The buyer has 5 days to inspect and reject non-conforming batches. Defective goods must be replaced, and the supplier indemnifies any consumer claim arising from a defect. Disputes go to arbitration.
When a batch arrives off-spec, the rejection and replacement clauses resolve it in a week, without either side arguing about what was promised.
Common mistakes
- No specification or quality standard, so "defective" has no agreed meaning.
- No acceptance or rejection process, which produces standoffs.
- Silence on GST and invoicing, jeopardising the buyer's input tax credit.
- No price revision mechanism, which turns an input cost rise into a mid-term dispute.
- No remedy for late or defective supply, leaving the buyer exposed exactly where the risk sits.
A drafting checklist
- Define scope, specifications and quality standards, attaching a spec sheet.
- Set pricing, a revision mechanism, payment terms and GST handling.
- Specify delivery timelines, risk and title transfer, and acceptance and rejection.
- Add warranties, remedies for defects, and delay penalties.
- Allocate liability and indemnity, with compliance and licensing duties on the vendor.
- Add term, termination, dispute resolution and force majeure.
Frequently asked questions
What should a vendor agreement include? Scope and specifications, pricing and payment, delivery and acceptance, quality and warranties, liability and indemnity, confidentiality, term and termination, and dispute resolution.
How do I protect against defective supply? Define the specifications, an inspection and rejection process, warranties, and remedies such as replacement or refund, plus an indemnity for resulting claims.
Should the agreement mention GST? Yes. Clear GST and invoicing terms are what let the buyer claim input tax credit and avoid a tax dispute.
Can I penalise late delivery? Yes, through a reasonable delay penalty or liquidated damages, ideally with time stated to be of the essence.
Do I need the vendor's licences referenced? For regulated goods, yes. Require the vendor to hold and maintain them as a contractual obligation.
How long should the inspection window be? Long enough to actually inspect and short enough that the vendor is not exposed indefinitely. Days rather than weeks, stated explicitly.
