Supplier Agreement Checklist: 12 Terms to Get in Writing

Updated September 2026 · 9 min read

Short answer: A supplier agreement checklist should cover 12 terms: products and specs, pricing, minimums, payment terms, lead times, shipping and risk, inspection, defects and returns, warranties and compliance, exclusivity, confidentiality, and how the deal ends or disputes get handled. If it isn’t written down, you’ll have a hard time enforcing it when something goes wrong.

Most wholesale problems aren’t about bad people. They come from two sides remembering a conversation differently. A clear agreement, even a simple one, prevents that. Use this supplier agreement checklist before your first big order, whether you’re a shop buying from a brand or a brand buying from a manufacturer.

This is general information, not legal advice. For large or ongoing contracts, have a business attorney in your state review the agreement.

Why do you need a written supplier agreement?

There’s a legal reason and a practical one.

The legal reason: In the U.S., sales of goods are mainly governed by Article 2 of the Uniform Commercial Code (UCC), which states adopt as their own law. Under the version most states use, a contract for the sale of goods for $500 or more generally isn’t enforceable unless there’s a signed record showing a contract was made. There are exceptions, but you don’t want to rely on them.

The practical reason: When a shipment shows up late, short, or damaged, the first question is always “what did we agree to?” A written agreement answers it in seconds.

What counts as “in writing”?

Format	Good for	Watch out for
Phone or in-person deal only	Nothing important	No proof of what was agreed
Email thread	Small, one-off orders	Terms scattered across many messages
Purchase order + supplier’s confirmation	Most regular wholesale orders	Conflicting fine print on each side’s forms
Signed supply agreement	Ongoing, large, or custom orders	Takes time; worth a legal review

For everyday orders, a detailed purchase order often does the job. Our guide on what to include in a purchase order covers that document. For bigger or recurring deals, use the checklist below.

The supplier agreement checklist: 12 terms to get in writing

1. Products and specifications

List exactly what you’re buying: SKU or item number, size, color, materials, weight, packaging, and labeling. For custom or private-label goods, attach an approved sample photo or spec sheet and state that production must match it. “Blue ceramic mug” invites surprises. “12 oz stoneware mug, glaze color matching approved sample #3, individually boxed” doesn’t.

2. Pricing and price changes

Write down the unit price, the currency, and what’s included (packaging, labels, freight to a certain point). Then add how prices can change. How much notice will the supplier give before an increase? Do open orders keep the old price? A 30- to 60-day notice period is a reasonable ask for ongoing deals.

3. Minimum order quantities

Spell out the minimum per order, per SKU, and per color if those differ. Note whether reorders have a lower minimum than the opening order. If you negotiated a smaller first run, get that exception in writing, or the next invoice may assume the standard minimum.

4. Payment terms

When is money due, and how? Common setups are full prepayment, a deposit with the balance before shipping, or net terms (like net 30) after delivery. Include accepted payment methods, any early-payment discount, and late fees. For overseas suppliers, confirm the bank details by phone before sending your first wire. Changed bank details by email are a classic scam.

5. Lead times and delivery dates

Get a ship date or a delivery window, not just “4 to 6 weeks.” Say what happens if the supplier misses it: can you cancel without penalty, get a discount, or require faster shipping at their cost? For seasonal goods, a “cancel if not shipped by” date protects you from receiving holiday stock in January.

6. Shipping, title, and risk of loss

Who books and pays for freight, and at what point do the goods become your responsibility? If a pallet is damaged in transit, this term decides who files the claim and who eats the loss. For international orders, name an Incoterms rule, like FOB or DDP, with a named place. Our guide to Incoterms for small importers explains the common options.

7. Inspection and acceptance

How long do you have to inspect a shipment and report problems? Seven to 14 days after delivery is a common window. If you use a third-party inspection before goods leave the factory, say who pays for it and what happens if the goods fail.

8. Defects, shortages, and returns

Define what counts as a defect and what the supplier will do about it: replace, credit, or refund. Say who pays return shipping. Some suppliers allow a small defect rate before they owe anything, so ask. Also cover shortages, when the box has fewer units than the invoice, and require photos and packing lists so claims are easy to prove.

9. Warranties and product compliance

The supplier should promise the goods meet the safety and labeling rules that apply where you’ll sell them. Children’s products, cosmetics, electronics, and food each have their own federal rules. Ask for test reports or certificates where required, and include an indemnity clause saying the supplier covers costs if its product causes a recall or a legal claim.

10. Exclusivity and territory

If the supplier promised not to sell to the shop across the street, or not to sell your custom design to anyone else, write it down. Define the area (a ZIP code, a city, a radius), the time period, and any sales targets you have to hit to keep the deal.

11. Confidentiality and intellectual property

For custom products, state that you own your designs, logos, molds, and artwork, and that the supplier can’t reuse them. Add a confidentiality clause covering your pricing, designs, and customer information. If you paid for molds or tooling, say who keeps them if the relationship ends.

12. Term, termination, and disputes

How long does the agreement last, and how can either side end it? Include a notice period and what happens to open orders. Then say how disputes get handled: which state’s law applies, where a case would be heard, and whether you’ll try mediation first. This matters most when your supplier is in another state or country.

How do you put a supplier agreement in place?

Watch out for suppliers who refuse to put anything in writing, rush you to pay before terms are clear, or keep changing bank details. Those are among the most common wholesale supplier red flags.

A quick note on conflicting forms

If your purchase order says one thing and the supplier’s invoice fine print says another, it can be unclear which terms apply. The fix is simple: agree on the key terms up front in one signed document, and have your purchase orders refer to it.

FAQ

Do small retailers really need a supplier agreement?

For small one-time orders, a clear purchase order and the supplier’s written confirmation are usually enough. For ongoing, custom, or large orders, a signed agreement is worth the effort.

Is an email a valid supplier agreement?

Emails can count as a written record in many cases, but terms spread across a long thread are easy to dispute. Summarize the final terms in one message and ask the supplier to confirm it.

What is the most important term in a supplier contract?

It depends on your risk, but defects and returns, payment terms, and delivery dates cause the most disputes for small businesses.

Can I use a supplier agreement template?

A template is a good starting point. Just make sure it covers all 12 terms above, fits your state’s law, and gets a legal review if the deal is large.
