Goods vs. Services Under the UCC: How to Determine Which Law Applies

Goods vs. Services Under the UCC: How to Determine Which Law Applies

One of the first questions in many American commercial-law disputes is deceptively simple:

Is this transaction for goods or for services?

The answer can determine which body of law governs the relationship.

If a transaction is a sale of goods, UCC Article 2 may apply. If it is primarily a transaction for services, common-law contract principles generally apply instead. When a transaction involves both goods and services, however, the answer becomes more complicated.

This distinction matters because Article 2 contains specialized rules concerning contract formation, warranties, delivery, risk of loss, acceptance, rejection, breach, and remedies. Common-law contract law operates differently in many of these areas.

Cornell Law School’s Legal Information Institute provides a useful starting point through its Cornell Wex materials on the sale of goods, which explain the basic concept underlying Article 2.

The goods-versus-services question therefore is not merely a matter of terminology. It is often a threshold legal classification problem.

---

The Basic Rule

The starting point is straightforward:

UCC Article 2 generally governs transactions involving the sale of goods.

Common-law contract principles generally govern contracts for services.

For example:

Transaction	General Legal Framework
Buying a refrigerator	UCC Article 2
Purchasing office furniture	UCC Article 2
Buying industrial machinery	UCC Article 2
Hiring a lawyer	Common law and professional regulation
Hiring an architect	Generally common law/statutory law
Hiring a consultant	Generally common law
Purchasing accounting services	Generally common law
Buying a computer with installation	Potentially mixed transaction
Hiring a contractor to build a house	Potentially mixed, depending on the jurisdiction and transaction

The difficulty lies in the transactions that do not fit neatly into either category.

---

What Are Goods Under the UCC?

The UCC generally defines goods as movable things.

The concept is broader than many people initially assume.

Goods can include:

• automobiles;
• computers;
• furniture;
• clothing;
• machinery;
• appliances;
• manufactured components;
• inventory;
• agricultural products;
• raw materials;
• food;
• electronics; and
• specially manufactured products.

A good does not have to be inexpensive, mass-produced, or intended for consumers.

A custom-built $2 million industrial machine can still be a good.

The central characteristic is generally that the item is movable.

---

What Are Services?

A service generally involves the performance of work, expertise, labor, advice, skill, or professional activity for another person.

Examples include:

• legal services;
• accounting;
• consulting;
• medical services;
• architectural services;
• engineering;
• advertising;
• software consulting;
• cleaning;
• repair;
• transportation;
• management services; and
• professional training.

Services are generally not “goods” simply because the provider produces something tangible while performing the service.

For example, a lawyer may produce a written legal memorandum.

The memorandum does not ordinarily transform the legal engagement into a sale of goods.

The substance of the transaction remains the provision of legal services.

---

Why the Classification Matters

The distinction is important because Article 2 contains rules that do not necessarily exist under ordinary common law.

For example, Article 2 provides specialized rules concerning:

• flexible contract formation;
• battle of the forms;
• warranties;
• perfect tender;
• rejection;
• cure;
• risk of loss;
• acceptance;
• revocation;
• commercial remedies; and
• certain Statute of Frauds requirements.

Suppose a seller delivers a product that does not conform to the contract.

Under Article 2, the buyer may have rights under the perfect tender rule.

Now imagine that a service provider performs defective professional services.

The legal analysis is not simply transferred from Article 2.

Different common-law and statutory principles may apply.

Thus, classification can change the legal consequences of the same factual dispute.

---

The Easy Cases

Some transactions are clearly sales of goods.

Example 1: Buying a car

A customer pays a dealer for an automobile.

The automobile is movable property.

Article 2 is generally relevant.

Example 2: Purchasing office furniture

A company purchases desks and chairs.

These are movable physical objects.

Article 2 generally applies.

Example 3: Purchasing raw materials

A manufacturer buys steel from a supplier.

The steel is movable property and is being sold for a price.

Article 2 generally governs.

The same analysis applies to many ordinary commercial purchases.

---

The Easy Service Cases

Other transactions are clearly services.

Example 1: Hiring a lawyer

A client pays an attorney for legal representation.

The transaction concerns professional expertise and legal work, not the sale of goods.

Common-law and professional rules generally apply.

Example 2: Hiring an accountant

A business hires an accountant to prepare financial statements.

Although the accountant produces documents, the substance of the relationship is the provision of professional services.

Example 3: Hiring a consultant

A company pays a consultant for strategic advice.

The transaction is primarily for expertise and services.

Article 2 generally does not govern the consulting relationship.

---

The Difficult Cases: Mixed Transactions

The hardest cases involve both goods and services.

Modern commerce frequently combines the two.

Consider a company that pays $250,000 for:

• specialized machinery;
• delivery;
• installation;
• software configuration;
• employee training; and
• technical support.

Is this a sale of machinery or a service contract?

The answer may not be obvious.

The transaction contains substantial elements of both.

These are commonly described as mixed transactions.

---

The Predominant Purpose Test

One widely used approach is the predominant purpose test, sometimes called the predominant-factor test.

The court asks:

What is the predominant purpose of the transaction?

Is the customer primarily purchasing:

goods, with services incidental to the transaction?

Or:

services, with goods incidental to the service?

If the predominant purpose is the sale of goods, Article 2 may govern.

If the predominant purpose is the provision of services, common-law principles may govern.

The test attempts to identify the economic substance of the transaction rather than relying on labels.

---

Factors Courts May Consider

Courts applying a predominant-purpose analysis may examine factors such as:

1. The language of the agreement

What does the contract describe itself as providing?

2. The nature of the business

Is the provider primarily a manufacturer, retailer, or service professional?

3. The relative value of goods and services

How much of the transaction’s value comes from the physical goods?

4. The purpose of the customer

What was the customer actually trying to obtain?

5. The nature of the work

Was the labor merely incidental to delivering the product, or was the product incidental to the service?

6. The parties’ expectations

What would the parties reasonably have understood themselves to be purchasing?

7. The structure of the transaction

Does the agreement resemble a product purchase or a professional-services engagement?

No single factor necessarily controls every case.

---

Example: Air-Conditioning Installation

Suppose a homeowner pays a company $8,000 to:

• purchase an air-conditioning unit;
• deliver it;
• install it;
• connect it to the home’s electrical system;
• configure the controls; and
• test the system.

There are both goods and services.

The air-conditioning unit is a good.

Installation is a service.

The question becomes whether the transaction is predominantly a sale of the unit or predominantly an installation service.

The answer may depend on the facts and the jurisdiction.

---

Example: Computer System Installation

Consider a company that pays $100,000 for:

• servers;
• networking hardware;
• installation;
• software configuration;
• cybersecurity setup; and
• employee training.

Suppose $70,000 represents hardware and $30,000 represents installation and related services.

That numerical division may strongly suggest a goods-oriented transaction, but it does not automatically determine the result.

The court may examine the entire agreement.

If the customer’s principal objective was obtaining the physical equipment, Article 2 may have substantial relevance.

---

Example: Custom Software

Software creates particularly difficult classification questions.

Suppose a company pays a developer $200,000 to create a customized software system.

The developer provides:

• programming;
• design;
• consulting;
• testing;
• implementation;
• maintenance; and
• a digital copy of the resulting software.

Is the transaction a sale of goods?

Historically, courts have struggled with software because it does not always fit neatly into the traditional physical concept of movable goods.

The answer can depend on:

• the nature of the software;
• whether it is custom-developed;
• whether it is standardized;
• whether physical media are involved;
• whether services dominate;
• applicable state law; and
• the specific contractual arrangement.

The growing importance of digital products demonstrates why the goods-versus-services distinction remains an evolving area of commercial law.

---

Tangible Results Do Not Automatically Create Goods

A common mistake is to assume:

“If something tangible is produced, it must be a good.”

That is not necessarily correct.

A service provider may produce tangible results.

An architect produces plans.

A lawyer produces documents.

A consultant produces reports.

A photographer produces photographs.

A repair technician may replace physical components.

Yet the overall transaction may still be predominantly a service relationship.

The law looks at the nature of the transaction, not merely whether something physical emerges at the end.

---

Goods Can Include Labor and Manufacturing

The opposite mistake is also possible.

A product can require substantial labor without ceasing to be a good.

Suppose a customer orders a custom-made piece of industrial equipment.

The manufacturer must:

• design it;
• fabricate it;
• assemble it;
• test it; and
• deliver it.

The presence of significant labor does not automatically make the transaction a service.

The ultimate object of the transaction may still be the sale of a movable product.

This is particularly important for specially manufactured goods.

---

Custom-Made Goods

A product does not have to be mass-produced to qualify as a good.

Consider:

• custom furniture;
• specialized machinery;
• tailored industrial components;
• custom medical devices; or
• made-to-order equipment.

The fact that the seller performs substantial design and manufacturing work does not necessarily transform the transaction into a service contract.

The relevant question remains the nature and substance of the bargain.

---

Construction Contracts

Construction agreements frequently illustrate the difficulty of classification.

Suppose a contractor agrees to build a structure.

The project may involve:

• lumber;
• concrete;
• steel;
• windows;
• electrical components;
• plumbing fixtures;
• labor;
• engineering;
• project management; and
• construction services.

Is this a sale of goods?

Generally, traditional construction contracts are treated as service-oriented or governed by specialized construction law rather than being treated simply as Article 2 sales.

But the analysis can become more complicated when the dispute concerns a particular component or separately negotiated sale of materials.

State law and the precise contractual relationship matter.

---

Repair Transactions

Repair transactions can also create classification questions.

Suppose a mechanic repairs a vehicle.

The mechanic:

• diagnoses the problem;
• provides labor;
• installs replacement parts; and
• tests the vehicle.

The transaction contains both services and goods.

The labor may be the predominant element, with replacement parts incidental to the repair.

But if a customer simply purchases replacement parts separately, the transaction is much more clearly a sale of goods.

The same physical item can therefore appear in different legal contexts.

---

Medical Transactions

Medical services can create another interesting distinction.

Suppose a patient visits a doctor and receives medical treatment.

The physician may use:

• medication;
• medical devices;
• bandages;
• implants; and
• diagnostic equipment.

That does not necessarily mean the patient’s transaction is a sale of goods.

The dominant relationship is usually the provision of medical services.

Again, the legal classification follows the substance of the transaction rather than simply identifying every physical item involved.

---

Food and Restaurant Transactions

Restaurant transactions can also involve both goods and services.

When a customer orders a meal, the restaurant provides:

• food;
• preparation;
• cooking;
• presentation;
• service;
• seating; and
• other hospitality functions.

The legal treatment of such transactions can depend on the applicable jurisdiction and the precise dispute.

The example demonstrates that the presence of a physical product does not automatically answer the classification question.

---

The Importance of the Contract

The parties’ contract can provide valuable evidence concerning the nature of the transaction.

Relevant provisions may describe:

• what is being purchased;
• what the seller must provide;
• how the price is allocated;
• what warranties apply;
• how installation occurs;
• who owns intellectual property;
• what constitutes completion; and
• what happens after delivery.

A carefully drafted agreement can therefore reduce classification uncertainty.

However, simply labeling a contract a “service agreement” does not necessarily make it one.

Courts may look beyond labels to the actual substance of the transaction.

---

Why Labels Are Not Conclusive

Imagine a contract titled:

“Professional Services Agreement.”

The agreement then requires the provider to manufacture and deliver 10,000 physical products.

Calling the document a service agreement does not automatically transform the transaction into a service contract.

Conversely, calling a contract a “Product Purchase Agreement” does not necessarily make a complex professional-services relationship an Article 2 sale.

The law generally examines substance over form.

---

Separate Contracts

Sometimes the parties enter into separate agreements.

For example:

Contract A: Purchase of computer hardware.

Contract B: Installation and consulting services.

This structure can make classification easier.

Article 2 may govern the hardware agreement while common-law principles govern the service agreement.

But the contracts may still be closely connected.

A dispute over one may affect the interpretation or performance of the other.

---

A Single Price Does Not Solve the Problem

A mixed transaction may have one total price.

That does not necessarily tell us whether Article 2 applies.

Suppose the customer pays $50,000 for:

• equipment;
• delivery;
• installation;
• training; and
• maintenance.

The fact that the contract contains one price does not eliminate the goods-versus-services issue.

The court may still examine the economic substance of the transaction.

---

Separately Stated Prices

A contract that separately identifies the price of goods and services can make classification easier.

For example:

Equipment: $40,000

Installation: $5,000

Training: $2,000

Maintenance: $3,000

The allocation provides evidence concerning the parties’ understanding.

It does not necessarily determine the legal result, but it can be useful evidence.

---

The Economic Substance of the Transaction

The deeper question in mixed transactions is often:

What was the buyer really purchasing?

Imagine paying $100,000 for a machine and $5,000 for installation.

The transaction looks primarily like a purchase of goods.

Now imagine paying $100,000 for a consulting engagement that happens to include $5,000 of specialized equipment.

The transaction looks very different.

The same dollar amounts can therefore produce different legal classifications depending on the nature of the bargain.

---

Article 2 Rules That May Become Important

Classification matters because Article 2 contains specialized rules.

If Article 2 applies, the parties may encounter rules concerning:

Contract formation

Commercial contracts can sometimes be formed despite open terms.

Battle of the forms

Conflicting purchase orders and acknowledgments receive specialized treatment.

Warranties

Express and implied warranties can arise under Article 2.

Perfect tender

A buyer may have significant rights when delivered goods fail to conform to the contract.

Cure

A seller may have an opportunity to correct a defective delivery in appropriate circumstances.

Risk of loss

The UCC provides specialized rules concerning when risk shifts between buyer and seller.

Acceptance and rejection

Article 2 provides detailed rules concerning inspection, acceptance, and rejection.

Remedies

Buyers and sellers receive specialized statutory remedies.

These rules are among the reasons the classification question can be outcome-determinative.

---

Common-Law Rules for Services

When a transaction falls outside Article 2, traditional contract law may become the principal framework.

Common-law contract doctrine addresses concepts such as:

• offer;
• acceptance;
• consideration;
• breach;
• substantial performance;
• material breach;
• damages;
• anticipatory repudiation;
• mitigation;
• conditions; and
• other contractual principles.

Some principles overlap with Article 2, but the details can differ significantly.

For example, the UCC’s perfect tender rule does not simply transfer into ordinary service contracts.

---

Goods and Services in a Digital Economy

The goods-versus-services distinction has become increasingly complicated as the economy has moved toward digital products.

Consider:

• cloud computing;
• software subscriptions;
• software-as-a-service;
• digital downloads;
• streaming services;
• online platforms;
• data services;
• cybersecurity subscriptions; and
• artificial-intelligence services.

These transactions may involve:

• intellectual property;
• licenses;
• services;
• digital information;
• physical equipment; and
• continuing access.

Traditional categories do not always map neatly onto these modern business models.

Consequently, lawyers must examine both the statutory framework and the particular jurisdiction’s treatment of digital transactions.

---

Software as a Borderline Category

Software is especially important because it may exist in several forms.

A company might:

1. purchase software on physical media;
2. download standardized software;
3. license software;
4. commission custom software development;
5. subscribe to cloud-based software; or
6. purchase software together with extensive consulting and implementation services.

These transactions are economically similar in some respects but legally distinct.

The presence of intellectual property rights can also introduce another layer of legal analysis.

The question is therefore not simply:

“Is software a good?”

It is:

What precisely did the parties contract to receive, and what legal regime does the applicable jurisdiction use to classify that transaction?

---

The Same Product Can Appear in Different Legal Relationships

Consider a computer.

Transaction A

A retailer sells the computer to a customer.

Likely: Article 2 sale of goods.

Transaction B

An IT consultant installs and configures the computer.

Likely: Service transaction.

Transaction C

A company hires an IT provider to manage its entire technology system and supplies the provider with equipment.

Likely: Primarily services, depending on the agreement.

Transaction D

A manufacturer sells 1,000 computers to a distributor and agrees to provide installation support.

Likely: Primarily goods, with ancillary services.

The physical object does not determine the legal relationship.

The transaction does.

---

A Practical Examination Framework

When confronted with a goods-versus-services question, use the following sequence.

Step 1: Identify exactly what was promised

Do not rely on the title of the contract.

Read the obligations.

Step 2: Identify the physical goods

What movable property, if any, is being transferred?

Step 3: Identify the services

What labor, expertise, advice, installation, design, or professional work is being provided?

Step 4: Determine whether the transaction is mixed

If both goods and services are significant, continue the analysis.

Step 5: Examine the predominant purpose

Ask what the transaction is primarily designed to accomplish.

Step 6: Examine the economic structure

Consider:

• price allocation;
• value of goods;
• value of services;
• importance of labor; and
• relationship between the components.

Step 7: Examine the parties’ expectations

What did the buyer believe it was purchasing?

What did the seller believe it was providing?

Step 8: Examine the jurisdiction

State law matters.

Courts do not necessarily apply identical tests or reach identical conclusions in every jurisdiction.

Step 9: Identify the consequences

If Article 2 applies, determine which UCC provisions govern.

If it does not, determine which common-law or statutory rules apply.

---

A Detailed Example

Suppose a company hires a technology provider for $500,000.

The provider agrees to supply:

• $300,000 in computer equipment;
• $75,000 in installation;
• $50,000 in software configuration;
• $50,000 in employee training; and
• $25,000 in ongoing support.

A dispute later arises because the equipment does not perform according to the contract.

The legal classification matters.

The transaction contains substantial goods and substantial services.

A court might examine:

• the relative value of the equipment;
• whether the equipment is the primary object;
• whether the services are necessary merely to make the equipment operational;
• the language of the contract;
• the parties’ expectations;
• whether the equipment was standardized or specially developed; and
• the applicable jurisdiction’s approach.

If Article 2 governs, warranty and conformity rules could become particularly important.

If the transaction is treated primarily as a service contract, common-law doctrines may control instead.

Thus, a seemingly technical classification question could determine the parties’ substantive rights.

---

Why the Distinction Is Sometimes Difficult

The difficulty exists because modern business transactions are not naturally divided into neat legal boxes.

Businesses increasingly sell solutions, not isolated products.

A company may purchase:

• hardware;
• software;
• installation;
• financing;
• maintenance;
• training;
• technical support; and
• consulting

from one provider under one agreement.

From a commercial perspective, this is one integrated transaction.

From a legal perspective, however, the transaction may contain several different components governed by different bodies of law.

This creates a central challenge for modern commercial law:

The law must classify transactions that businesses increasingly design to cross traditional categories.

---

Why the Classification Matters Beyond Article 2

The goods-versus-services distinction can affect more than contract rules.

It may influence:

• warranties;
• consumer protections;
• limitation-of-liability provisions;
• statutes of limitation;
• remedies;
• damages;
• procedural rules;
• choice-of-law analysis; and
• regulatory requirements.

Different statutes may use different definitions of goods and services.

Therefore, a lawyer should not assume that a classification under one statute automatically determines classification under every other law.

---

Common Misunderstandings

“If a physical object is involved, Article 2 applies.”

Not necessarily.

A physical object may be incidental to a predominantly service-oriented transaction.

“If labor is involved, the transaction is a service.”

Not necessarily.

Manufacturing goods can involve substantial labor and remain sales of goods.

“The contract title determines the answer.”

No.

Courts generally look at the substance of the transaction.

“The most expensive component automatically controls.”

Not necessarily.

Price is relevant, but courts may consider numerous factors.

“Every mixed transaction is governed half by the UCC and half by common law.”

Not necessarily.

Many jurisdictions use a predominant-purpose approach rather than automatically dividing the transaction.

“Software is always a good.”

No.

Software transactions can take many forms, and applicable law varies.

“If Article 2 does not apply, there is no commercial law.”

False.

Common-law contract principles and numerous other statutes can govern service transactions.

---

The Deeper Principle

The goods-versus-services distinction illustrates a larger principle of legal reasoning:

Before applying a legal rule, we must first determine what kind of legal relationship exists.

Law is full of classification questions.

Is someone an employee or an independent contractor?

Is property real or personal?

Is a payment a gift or consideration?

Is conduct criminal or merely tortious?

Is a transaction a sale or a service?

These classifications are not merely semantic.

They determine which legal rules become available.

The goods-versus-services distinction is therefore a useful example of how lawyers actually reason.

The lawyer does not begin by asking:

“What does Article 2 say?”

The lawyer begins with:

“Does Article 2 apply at all?”

Only then does the substantive analysis begin.

---

Frequently Asked Questions

What is the difference between goods and services under the UCC?

Goods are generally movable things sold in a transaction. Services generally involve labor, expertise, advice, or other performance. Article 2 generally applies to sales of goods rather than pure services.

What happens when a contract involves both goods and services?

The transaction is considered a mixed transaction. Courts may use a predominant-purpose or similar test to determine whether the transaction is primarily for goods or services.

Does the more expensive part of the transaction determine whether Article 2 applies?

Not automatically. The value of goods and services is relevant, but courts may consider the entire transaction.

Does installing a product turn a sale into a service contract?

Not necessarily. Installation may be incidental to a sale of goods. The overall substance of the transaction must be examined.

Are custom-made products goods?

Generally, yes. A product can be a good even if it is specially manufactured for one buyer.

Does the UCC govern software?

It depends on the nature of the software transaction and applicable law. Standardized software, custom development, licensing, subscriptions, and software bundled with services can present different legal questions.

Does the title of a contract determine whether it is a goods or services contract?

No. Courts may examine the substance of the transaction rather than relying solely on the contract’s title.

Why does the distinction matter?

Because Article 2 contains specialized rules concerning formation, warranties, delivery, risk of loss, acceptance, rejection, breach, and remedies that may not apply to service contracts.

---

Conclusion

The distinction between goods and services is one of the foundational classification problems in American commercial law.

At first glance, the rule seems easy: goods are products, services are work.

Modern commerce makes the reality much more complicated.

Businesses increasingly sell integrated packages containing equipment, software, installation, consulting, maintenance, training, and support. A single transaction may therefore contain both goods and services and may not fit comfortably within traditional legal categories.

The solution is not to focus mechanically on individual components.

The better approach is to examine the substance and purpose of the transaction.

What was the buyer primarily trying to obtain?

What was the seller primarily undertaking to provide?

How are the goods and services related?

What does the contract say?

How is the price structured?

What does the applicable state law provide?

These questions help determine whether Article 2 applies.

The distinction ultimately teaches an important lesson about commercial law: legal rules cannot be applied intelligently until the underlying transaction has been correctly classified.

That is why the goods-versus-services question should often be the starting point—not the final step—of an Article 2 analysis.
