# What is a purchase agreement: parties, price, closing

Copy for LLM

A purchase agreement is a contract in which a seller agrees to transfer goods, property, or a business to a buyer for a stated price, on stated conditions. Picture a regional bakery buying two commercial ovens from an equipment dealer for $48,000. The agreement says which ovens, when they arrive, when the balance is paid, and who carries the loss if a forklift drops one on the loading dock. Without those terms, the parties fall back on default rules that neither of them chose.

This guide covers purchase agreements for goods and business assets in the United States, mainly under Article 2 of the Uniform Commercial Code (UCC) as the states enact it. It is general information, not legal advice. Real estate sales follow separate state property rules, covered in our guide to [purchase agreements in real estate](https://contracko.com/blog/purchase-agreement-real-estate).

You will find the parties, the clauses that carry the most risk, the dates to track, and a checklist to run against a signed agreement.

## Purchase agreement: purpose and uses

A purchase agreement fixes four things: what is sold, what it costs, when ownership and risk move, and what happens if something goes wrong. Everything else in the document supports one of those four jobs.

Under UCC Article 2, a "sale" consists in the passing of title from the seller to the buyer for a price [1]. A "contract for sale" includes both a present sale and a contract to sell goods at a future time [1]. Most purchase agreements are the second kind. They are signed today and performed later, at delivery or closing.

### Common types and what governs them

The name stays the same across very different deals. What changes is the asset, and with it the law and the risk.

| Type | What is bought | Main US rules |
| --- | --- | --- |
| Goods purchase agreement | Equipment, inventory, vehicles, materials | UCC Article 2, as enacted in each state |
| Real estate purchase agreement | Land and buildings | State real property law and local practice |
| Asset purchase agreement | Selected assets and liabilities of a business | Contract law, plus Article 2 for any goods |
| Stock or share purchase agreement | Ownership interests in a company | Contract and corporate law |
| Power purchase agreement | Electricity over a long term | Energy regulation and contract law |

Two of those have their own guides. A [power purchase agreement](https://contracko.com/blog/what-is-a-power-purchase-agreement) is a long-term supply deal priced per unit of energy, and its risks look more like a supply contract than a one-off sale. Recurring buying from suppliers is usually papered as a [procurement contract](https://contracko.com/blog/what-is-a-procurement-contract), which governs many orders rather than one transfer.

### Purchase agreement or something else?

Several nearby documents are easy to confuse with a purchase agreement:

- Purchase order (PO). A buyer's order for specific goods. It can form a contract on its own once the seller accepts it, or it can be one order placed under a framework agreement.
- Bill of sale. The document that transfers title at the moment of handover. It records that the sale happened; the purchase agreement records the deal that led to it. Contracko has a [bill of sale template](https://contracko.com/contract-templates/bill-of-sale) for that step.
- Purchase conditions. A buyer's standard terms, often printed on the back of a PO. The glossary entry on [purchase conditions](https://contracko.com/glossary/purchase-conditions) explains how they interact with a seller's own terms.

### How a purchase agreement is formed

Under UCC Article 2, a contract for sale of goods may be made in any manner sufficient to show agreement, including conduct by both parties [1]. It does not fail because some terms are left open, if the parties intended a contract and a court has a reasonably certain basis for a remedy [1].

Writing still matters. Under UCC section 2-201, a contract for the sale of goods for $500 or more generally needs some writing showing that a contract was made. The party being held to it, or its authorized agent, must have signed that writing [1]. The section has exceptions [1]. They cover goods specially made for the buyer and unsuitable for sale to others. That exception applies once the seller, before notice of repudiation and in circumstances that reasonably indicate the goods are for the buyer, has made a substantial beginning of manufacture or commitments to procure the goods. They also cover admissions in court, up to the quantity admitted, and goods already paid for or received and accepted. Even where it is met, the contract is not enforceable beyond the quantity shown in the writing [1].

A signature does not have to be on paper. The federal Electronic Signatures in Global and National Commerce Act covers contracts in or affecting interstate or foreign commerce. Such a contract may not be denied legal effect solely because an electronic signature or electronic record was used to form it [2].

Cross-border sales add one more layer. The United Nations Convention on Contracts for the International Sale of Goods (CISG) applies to sales of goods between businesses whose places of business are in different contracting states [3]. The United States has been a party since 1988 [3]. The convention does not cover sales to consumers or sales of services [3].

## Purchase agreement: parties

Every purchase agreement has a buyer and a seller. Larger deals add people who hold money, check conditions, or carry the goods.

| Party | Typical responsibilities |
| --- | --- |
| Seller | Delivers conforming goods or assets, transfers good title, gives agreed warranties |
| Buyer | Pays the price, inspects on time, accepts or rejects, gives notice of defects |
| Signatories | Bind their organizations; their authority should be confirmed before signing |
| Carrier | Moves the goods; its handover often decides when risk passes |
| Escrow agent or lender | Holds deposits or funds the price until closing conditions are met |
| Guarantor | Promises payment or performance if the buyer or seller does not deliver |

Whether a party is a merchant matters under UCC Article 2. Some default rules apply only to merchants, or only between merchants. For example, the implied warranty of merchantability arises only when the seller is a merchant with respect to goods of that kind [1]. Between merchants, a written confirmation can satisfy the writing requirement against a receiving party who does not object in writing within 10 days of receiving it [1].

In practice, the name on the signature block is the part most often wrong. A sister company signs instead of the operating entity, or a manager signs above their authority. Check the legal name, registration details, and signing authority of both sides against the deal you agreed.

## Purchase agreement: key clauses

These clauses decide who carries cost and risk. Each one replaces a default rule, so leaving it out is a choice too.

### Description, quantity, and quality

Describe the goods precisely enough that a stranger could check a delivery against the contract. Include model numbers, specifications, quantities, and any sample. Under UCC Article 2, a description or sample that is part of the basis of the bargain creates an express warranty that the goods will conform to it [1].

### Price and payment

State the price, the currency, any deposit, and when each payment falls due. Under UCC Article 2, a contract can exist even if the price is not settled. If the agreement says nothing about price, or the parties fail to agree on it, the price is a reasonable price at the time for delivery [1]. That rule applies only if the parties intended to be bound without a fixed price. If they intended no contract until a price was set, there is none [1].

Unless otherwise agreed, payment under UCC Article 2 is due at the time and place the buyer is to receive the goods [1]. Where the seller ships on credit, the credit period runs from shipment. Post-dating the invoice or delaying its dispatch delays the start of the credit period by the same amount [1].

### Delivery terms

Say where and when delivery happens. Under UCC Article 2, unless otherwise agreed, the place for delivery is the seller's place of business [1]. If the contract names no time for shipment or delivery, the time is a reasonable time [1].

Shipping terms carry legal meaning. Under UCC section 2-319, free on board (FOB) the place of shipment means the seller bears the expense and risk of putting the goods into the carrier's possession [1]. FOB the place of destination means the seller transports the goods there at its own expense and risk and tenders delivery there [1].

### Title and risk of loss

Title and risk are separate questions, and the contract should answer both. Under UCC Article 2, title passes in any manner and on any conditions the parties explicitly agree, subject to the Article's limits [1]. If they agree nothing, title generally passes when the seller completes physical delivery [1].

Risk of loss follows its own default rules under UCC section 2-509 [1]:

- If the seller ships by carrier and is not required to deliver at a particular destination, risk passes when the goods are duly delivered to the carrier.
- If the seller must deliver at a particular destination, risk passes when the goods are duly tendered there so the buyer can take delivery.
- If a warehouse or other bailee holds the goods for delivery without moving them, separate rules tied to documents of title and the bailee's acknowledgment apply.
- In all other cases, risk passes on the buyer's receipt of the goods if the seller is a merchant, and otherwise on tender of delivery.

The parties can agree otherwise, and the Article's rules on sale on approval and on the effect of breach can also shift risk [1]. In the bakery example, a destination term keeps the risk of a dropped oven with the dealer until delivery is tendered at the bakery.

### Inspection and acceptance

Under UCC Article 2, unless otherwise agreed, the buyer has a right to inspect goods before payment or acceptance, at any reasonable place, time, and manner [1]. Payment terms such as cash on delivery can remove that right before payment [1]. If the goods or the tender fail in any respect to conform, the buyer may reject the whole, accept the whole, or accept some commercial units and reject the rest [1]. That rule is subject to the Article's rules on installment contracts and any agreed limitation of remedies [1].

Rejection must happen within a reasonable time after delivery or tender, and it is ineffective unless the buyer seasonably notifies the seller [1]. Acceptance can also happen by default. It occurs if the buyer, after a reasonable opportunity to inspect, fails to reject effectively, or does any act inconsistent with the seller's ownership [1]. A contract that sets a clear inspection window and acceptance test removes most of that uncertainty.

### Warranties and disclaimers

Under UCC Article 2, an affirmation of fact or promise about the goods that becomes part of the basis of the bargain creates an express warranty [1]. Formal words such as "warrant" are not needed. A statement of mere value, opinion, or commendation does not create one [1].

Disclaimers have form rules. To exclude or modify the implied warranty of merchantability, the language must mention merchantability and, in a writing, be conspicuous [1]. An exclusion of the implied warranty of fitness must be in writing and conspicuous [1]. Expressions like "as is" or "with all faults" generally exclude implied warranties, unless the circumstances indicate otherwise [1].

### Closing conditions

Closing conditions are the events that must happen before either side has to complete the purchase. They matter most in larger deals, where signing and closing are weeks or months apart. Common conditions include:

- Satisfactory inspection or due diligence
- Financing for the buyer
- Clear title to the assets, with liens released
- Consents from landlords, lenders, or key customers whose contracts are being transferred
- Regulatory approvals

Some approvals are set by statute. Under federal law, certain acquisitions of voting securities or assets above dollar thresholds cannot close until both parties file a premerger notification and a waiting period expires [4]. The thresholds are adjusted each year [4].

A good closing clause names each condition, who must satisfy it, how satisfaction is shown, and an outside date. It should also say whether either side can waive a condition, and what happens to any deposit if the deal does not close.

### Remedies, assurance, and disputes

Remedy clauses limit liability, set liquidated damages, or restrict the buyer to repair or replacement. UCC Article 2 allows remedies for breach of warranty to be limited under its sections on liquidated damages and contractual modification of remedy [1].

UCC Article 2 also gives each party a self-help tool. When reasonable grounds for insecurity arise, a party may demand adequate assurance of due performance in writing [1]. After a justified demand, failing to provide adequate assurance within a reasonable time not exceeding thirty days is a repudiation [1]. Finish with governing law, venue, and any arbitration or mediation step, so a dispute does not start with an argument about where to have it.

## Dates and lifecycle events

A purchase agreement creates most of its work after signature. These are the dates that decide rights, and each one belongs in a calendar with an owner.

| Event | What to track | Default rule in UCC Article 2 |
| --- | --- | --- |
| Signing | Effective date, deposit due date | None; set by contract |
| Merchant confirmation received | Objection deadline | Written objection within 10 days of receipt [1] |
| Closing conditions | Each condition's deadline, outside date | None; set by contract |
| Delivery or closing | Delivery date and place, shipping term | Reasonable time; seller's place of business [1] |
| Inspection and acceptance | End of inspection window | Rejection within a reasonable time, with seasonable notice [1] |
| Payment | Due date, credit period start | At receipt of goods; credit runs from shipment [1] |
| Defect discovered | Notice of breach deadline | Notice within a reasonable time after discovery [1] |
| Warranty period | Warranty end date | Set by contract |
| Claims deadline | Limitation date | Four years from accrual, reducible to one year [1] |

Two of those defaults deserve detail. First, under UCC section 2-607, a buyer who has accepted a tender must notify the seller of breach within a reasonable time. The clock runs from when the buyer discovers or should have discovered the breach. Missing it bars the buyer from any remedy [1].

Second, under UCC section 2-725, an action for breach of a contract for sale must be commenced within four years after the cause of action accrues [1]. The original agreement may reduce that period to not less than one year, but may not extend it [1]. A breach of warranty generally accrues at tender of delivery, regardless of whether the buyer knows about it. The exception is a warranty that explicitly extends to future performance, where discovery must await that performance [1]. A one-year limitation clause buried in seller terms can therefore expire before a latent defect shows up.

Ongoing supply arrangements have one more date. Under UCC Article 2, a contract for successive performances that is indefinite in duration is valid for a reasonable time. Termination by one party, except on an agreed event, requires reasonable notification to the other [1]. For repeat orders, a [purchase order deadline reminder](https://contracko.com/contract-reminder-tools/purchase-order-deadline-reminder) helps keep delivery and acceptance dates visible.

## Risks and common mistakes

Most purchase agreement problems trace back to a missing term, a missed date, or the wrong set of terms.

Battle of the forms. The buyer sends a PO on its conditions; the seller replies with an acknowledgement on its own. Under UCC section 2-207, a definite acceptance can form a contract even though it states additional or different terms [1]. That does not apply if the acceptance is expressly made conditional on assent to those terms. Between merchants, the additional terms become part of the contract unless the offer limits acceptance to its own terms, they materially alter it, or notice of objection is given in time [1]. Decide which document governs and say so in both.

Open-ended closing conditions. A condition with no outside date leaves the deal open indefinitely. A deposit without a refund rule turns a failed closing into a dispute.

Silence on risk of loss. Default rules may put the risk of a damaged shipment on the party who least expects it. Pick a shipping term and an insurance obligation deliberately.

Accepting by accident. Putting goods into use, reselling them, or simply not rejecting them in time can count as acceptance [1]. Once accepted, goods cannot be rejected, and the buyer must pay at the contract rate [1].

Disclaimers that fail the form test. A warranty disclaimer buried in small print may not meet the conspicuousness requirement in UCC section 2-316 [1]. Sellers relying on one should check how it is presented.

Unnoticed minimum commitments. Some agreements oblige the buyer to take a minimum volume over a period. The glossary entry on a [purchase obligation](https://contracko.com/glossary/purchase-obligation) explains how these clauses shift cost to the buyer.

Lost paper. The signed version sits in one inbox, the amendment in another, and the seller's acknowledgement in a third. When a dispute starts, nobody can show which terms apply.

Before signing a supply-side deal, the [supplier agreement review tool](https://contracko.com/tools/supplier-agreement-review) checks an uploaded draft for terms like these.

## Contract-management checklist

Run this list when a purchase agreement is signed, and again before each key date.

Capture at signing

1. Full legal names of buyer and seller, and the signatories' authority.
2. Description, quantities, specifications, and any sample or model referenced.
3. Price, currency, deposit, payment schedule, and credit terms.
4. Delivery place, delivery date, and shipping term.
5. When title passes and when risk of loss passes.
6. Every closing condition, its owner, and the outside date.
7. Inspection window and the acceptance test.
8. Express warranties, disclaimers, and any limitation of remedies.
9. Notice addresses and the required form of notice.
10. Governing law, venue, and any shortened limitation period.

Diarise

1. Deposit and payment due dates.
2. Each closing-condition deadline and the outside date.
3. Delivery date and the end of the inspection window.
4. Warranty end date.
5. The contractual or statutory claims deadline.

Review on a cadence

1. Weekly before closing, check the status of each open condition.
2. On delivery, record inspection results and any rejection or acceptance notice.
3. Before the warranty ends, confirm whether any defect claims need notice.
4. Quarterly for ongoing supply, compare deliveries and invoices with the agreed terms.
