Business-to-business transactions under the UCC are governed primarily by Article 2 of the Uniform Commercial Code, which sets default rules for contract formation, delivery, risk of loss, warranties, payment, and remedies whenever one business sells goods to another.1Uniform Law Commission. Uniform Commercial Code Every state except Louisiana has adopted some version of Article 2, so the same core principles follow the shipment whether a manufacturer in Ohio is sending fasteners to Texas or a lumber yard in Oregon is supplying a builder next door. The rules differ sharply from consumer sales law because the UCC treats both sides as experienced professionals who know their industry, read what they sign, and raise problems promptly.
That professional-to-professional framework matters. Courts expect merchants to understand standard trade practices, so some of the protections a consumer would get are either weakened or missing outright. The upside is predictability. The downside is that routine mistakes, like missing a disclaimer or ignoring a shipping term, can carry real financial weight.
When a Contract Actually Exists
Article 2 applies only to sales of goods, meaning tangible, movable products. It does not cover pure service agreements or real estate. If your transaction involves physical products changing hands between two businesses, the UCC’s rules fill in whatever your contract leaves unsaid.
The $500 Writing Requirement
Any contract for the sale of goods priced at $500 or more must be supported by some writing to be enforceable.2Legal Information Institute. UCC 2-201 Formal Requirements Statute of Frauds The writing does not have to be a polished contract. A purchase order, an email confirmation, or a signed memo can do the job as long as it identifies the parties, describes the goods, and states the quantity. Quantity is the one term that absolutely must appear, because a court will not enforce the deal beyond the quantity the document shows. Price and delivery date can be filled in later from UCC defaults.
There are exceptions worth knowing. Specially manufactured goods the seller has already started producing can be enforced without a signed writing. So can goods the buyer has already received and accepted, and agreements both parties admit in court. Between merchants, a written confirmation sent by one side that the other does not object to within ten days satisfies the requirement, which is why ignoring an unsolicited confirmation in the inbox is a bad habit.
Battle of the Forms
In the real world, buyers send purchase orders and sellers respond with acknowledgments containing different or additional terms. Under UCC Section 2-207, that response still counts as an acceptance rather than a counteroffer, unless the seller explicitly conditions acceptance on the buyer agreeing to every new term.3Legal Information Institute. UCC 2-207 Additional Terms in Acceptance or Confirmation This is a deliberate break from the old common-law “mirror image” rule, which would have killed any deal where the forms did not match perfectly.
When the two forms conflict on a specific term, courts in many jurisdictions apply the knockout rule: the conflicting terms cancel each other, and the UCC’s default provisions fill the gap.3Legal Information Institute. UCC 2-207 Additional Terms in Acceptance or Confirmation Even when the parties never sign a single unified contract, their conduct can establish an enforceable agreement. Months of orders followed by shipments count as a contract built on whatever terms both sides agreed to, with the UCC covering the rest. This is where most B2B disputes quietly begin. Companies trade on boilerplate for years, and no one reads the fine print until something breaks.
Warranties That Attach Automatically
Two implied warranties come with almost every B2B sale by default, and many sellers do not realize they are making these promises until a buyer invokes them.
The warranty of merchantability means the goods must be fit for their ordinary purpose. Industrial adhesive has to bond materials. Food-grade packaging cannot contaminate what it holds. This warranty arises automatically whenever the seller is a merchant dealing in that type of goods.
The warranty of fitness for a particular purpose is narrower but can create larger exposure. It applies when the seller knows the buyer needs the goods for a specific, non-standard use and the buyer relies on the seller’s expertise to pick the right product.4Legal Information Institute. UCC 2-315 Implied Warranty Fitness for Particular Purpose A buyer who tells a chemical supplier it needs a product capable of withstanding 400-degree heat in a food processing line, and then gets what the seller recommended, is covered by this warranty even if the product’s spec sheet never mentioned that application.
Disclaiming the Warranties
Sellers can disclaim implied warranties, but the UCC imposes specific requirements that trip companies up regularly. To disclaim merchantability, the disclaimer must mention the word “merchantability” by name and, if written, must be conspicuous. To disclaim fitness, a conspicuous written statement is required. Blanket language like “sold as-is” or “with all faults” can also work for both, but buried fine print in a dense terms-and-conditions document may not qualify as conspicuous if a reasonable person would miss it.
Beyond disclaimers, sellers routinely cap their liability for consequential damages, which covers things like the buyer’s lost profits and downstream business disruption. The UCC allows these caps in commercial contracts and does not treat them as presumptively unfair the way it does in consumer transactions.5Legal Information Institute. UCC 2-719 Contractual Modification or Limitation of Remedy A typical clause caps the seller’s total liability at the purchase price of the defective goods. Courts generally enforce these provisions between sophisticated businesses, with one important limit: if the limitation effectively eliminates all remedies and leaves the buyer with nothing, a court can set it aside.
Shipping Terms and Who Bears the Loss
One of the most consequential questions in any B2B sale sounds trivial until something goes wrong: who bears the loss if goods are damaged or destroyed in transit? The answer turns on whether the contract is a shipment contract or a destination contract.
In a shipment contract, risk transfers to the buyer the moment the seller delivers the goods to the carrier. A truckload of components destroyed in an accident after the carrier picks it up is the buyer’s loss. In a destination contract, the seller carries the risk until the goods arrive at the buyer’s location and are tendered for delivery.6Legal Information Institute. UCC 2-509 Risk of Loss in the Absence of Breach The parties can override these defaults by agreement, and most sophisticated contracts do, using standardized terms like FOB Shipping Point (a shipment contract) or FOB Destination (a destination contract).
Getting this wrong carries real cost. A buyer operating under a shipment contract without cargo insurance is betting that nothing happens between the seller’s loading dock and its own. A seller shipping under destination terms needs its own coverage until delivery is complete. The shipping term in the purchase order controls this allocation, and it deserves more attention than it typically gets.
Inspecting and Rejecting Goods
Before paying, a buyer has the right to inspect the goods at any reasonable time and place and in any reasonable manner. When goods ship by carrier, inspection happens after arrival. The main exception is cash-on-delivery terms: under C.O.D., the buyer must pay before inspecting unless the parties agreed otherwise.7Legal Information Institute. UCC 2-513 Buyers Right to Inspection of Goods Paying under C.O.D. is not acceptance, so the buyer can still reject after paying and inspecting.
The Perfect Tender Rule
Under the UCC’s perfect tender rule, a buyer can reject an entire shipment if the goods fail to conform to the contract in any respect.8Legal Information Institute. UCC 2-601 Buyers Rights on Improper Delivery The buyer can also accept the whole shipment or accept some commercial units and reject the rest. Sellers who assume minor defects will be tolerated are taking a real risk.
The rule is softer for installment contracts, where goods arrive in multiple separate deliveries. A buyer can only reject a particular installment if the defect substantially impairs its value and the seller cannot cure it. Canceling the entire contract requires a defect that substantially impairs the value of the whole deal.9Legal Information Institute. UCC 2-612 Installment Contract Breach This matters because most ongoing supplier relationships involve repeated deliveries, and the higher substantial-impairment threshold prevents buyers from using one minor defect to walk away from a contract they no longer want.
Demanding Assurance of Performance
When one party has reasonable grounds to doubt the other will follow through, it can send a written demand for adequate assurance of performance and suspend its own obligations until it gets a satisfactory response. Failing to respond within 30 days is treated as repudiation. Between merchants, both the reasonableness of the insecurity and the adequacy of any assurance are judged by commercial standards. This mechanism comes up most often when a buyer learns a key supplier is in financial trouble, or when a seller discovers a buyer has been slow-paying other vendors.
Payment Terms and Late-Payment Interest
Most B2B transactions do not involve payment at the time of sale. Sellers extend trade credit, giving the buyer a set number of days to pay after receiving the goods or the invoice. The common structures are Net 30, Net 60, and Net 90, meaning the full invoice amount is due within 30, 60, or 90 days.
Early-payment discounts are a standard sweetener. A term written as “2/10 Net 30” gives the buyer a 2 percent discount for paying within 10 days, with the full amount due at 30. The 2 percent looks small, but annualized it is a meaningful cost for buyers who skip it. Industry norms vary widely. Petroleum transactions often settle within one or two days, while construction and manufacturing commonly run 60 to 90 days. The party with more leverage sets the terms, and buyers tend to push for longer windows when interest rates are high.
Contracts should specify an interest rate for overdue invoices. When they don’t, most states apply a statutory legal rate that is often modest. For reference, the federal prompt payment rate for government contracts during the first half of 2026 is 4.125 percent per year.10Federal Register. Prompt Payment Interest Rate Contract Disputes Act Private contracts can set higher rates, but every state has usury limits capping the maximum. Many states exempt commercial loans and credit from their usury caps entirely, but not all, so setting a rate above 15 or 18 percent without checking local law is risky.
Sellers extending large credit lines can also protect their receivables through trade credit insurance, which covers losses when a buyer cannot pay due to bankruptcy, insolvency, or similar financial failure. The coverage lets sellers offer more generous terms without shouldering the full default risk, which can be a competitive advantage when courting large buyers or expanding into unfamiliar markets.
Remedies When the Deal Breaks Down
The UCC gives each side a structured menu of remedies. What is available depends on who breached and how far the transaction has progressed.
If the Seller Breaches
When a seller fails to deliver, ships defective goods, or repudiates the contract, the buyer can cancel and recover any payments already made. Beyond that, the buyer has two main damage paths:11Legal Information Institute. UCC 2-711 Buyers Remedies in General
- Cover. The buyer purchases substitute goods from another source and recovers the difference between the cover price and the original contract price from the breaching seller.
- Market-price damages. If the buyer does not cover, it can recover the difference between the market price at the time it learned of the breach and the contract price.
In limited situations, the buyer can also obtain specific performance, meaning a court order requiring the seller to deliver the actual goods. This remedy is available when the goods are unique or when other circumstances make damages inadequate.11Legal Information Institute. UCC 2-711 Buyers Remedies in General A buyer who has already paid for goods it later rejects also holds a security interest in those goods for the payments made, and can resell them to recoup its costs.
If the Buyer Breaches
When a buyer wrongfully rejects goods, revokes acceptance, or fails to pay, the seller has its own options:12Legal Information Institute. UCC 2-703 Sellers Remedies in General
- Withhold or stop delivery. The seller can hold back unshipped goods and, in some cases, stop goods already with a carrier.
- Resell and recover damages. The seller resells the goods to another buyer and sues for the difference between the resale price and the original contract price.
- Recover the full price. If the seller cannot resell the goods at a reasonable price, it can sue for the full contract price.
- Cancel. The seller can terminate the contract while preserving its right to sue for damages.
Both sides can recover incidental damages like shipping costs, storage fees, and other expenses caused by the breach. The four-year statute of limitations for sale-of-goods claims applies to both parties. They can shorten it by agreement to as little as one year but cannot extend it beyond four.
Dispute Resolution Clauses
Most well-drafted B2B contracts include a dispute resolution clause specifying whether disagreements go to arbitration, mediation, or litigation. Arbitration is the dominant choice in commercial contracts because it is generally faster and more private than court proceedings.
Under the Federal Arbitration Act, a written agreement to arbitrate a dispute arising from a commercial transaction is valid, irrevocable, and enforceable, with only narrow exceptions for fraud or other grounds that would invalidate any contract.13Office of the Law Revision Counsel. 9 USC 2 – Validity Irrevocability and Enforcement of Agreements to Arbitrate Courts hold sophisticated commercial parties to a higher standard than consumers and routinely enforce arbitration clauses without requiring explicit language about waiving the right to a jury trial. The reasoning is straightforward: a business negotiating a supply agreement is presumed to understand what it signs.
Contracts without a dispute resolution clause default to litigation in the appropriate court, which is slower and more expensive but gives the losing party a broader right to appeal. Whether the contract requires arbitration or stays silent, the four-year limitations period for goods-related claims still applies, and both parties should document any breach promptly to keep every option open.
