Implied Warranty
An unwritten guarantee created by law that a product or service meets a basic standard.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Implied Warranty?
An implied warranty is a guarantee imposed by law - not written into the contract - that a product or service meets a minimum standard of quality or suitability. Unlike an express warranty that a seller actively makes, implied warranties arise automatically under the Uniform Commercial Code (UCC) whenever a merchant sells goods.
There are two primary implied warranties under UCC Article 2: the implied warranty of merchantability (the goods work as expected for ordinary use) and the implied warranty of fitness for a particular purpose (the goods will work for a specific use the buyer communicated to the seller). Both can expose sellers to liability if the goods fail, even if the contract says nothing about quality.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Implied Warranty of Merchantability
Under UCC Section 2-314, any merchant who sells goods in the ordinary course of business automatically warrants that those goods are fit for their ordinary purpose, of average quality, adequately packaged, and conform to any label claims. A restaurant that serves food, a car dealer that sells vehicles, and a software vendor that sells packaged software all owe this warranty.Implied Warranty of Fitness for a Particular Purpose
Under UCC Section 2-315, if a seller knows the buyer needs goods for a specific purpose and the buyer relies on the seller's judgment to select suitable goods, the seller impliedly warrants the goods will be fit for that purpose. This warranty arises from the seller's knowledge and the buyer's reliance - not just from the sale itself.Implied Warranty in Service Contracts
Services are governed by common law, not the UCC. Courts in most states imply a warranty that services will be performed in a workmanlike manner - meaning with the skill and care a reasonably competent professional would use. Professionals like architects, accountants, and IT consultants typically owe this warranty.Disclaiming Implied Warranties
Sellers can disclaim implied warranties under UCC Section 2-316, but only if done conspicuously and with specific language. To disclaim merchantability, the word "merchantability" must appear in the disclaimer. Blanket "as-is" language can disclaim all implied warranties if it is conspicuous. Courts scrutinize disclaimers that are buried in fine print.Real-World Example
A restaurant equipment supplier sells a commercial refrigeration unit to ColdStart Catering. The supplier knows ColdStart needs it for storing raw seafood at specific temperatures. The unit is defective and fails to maintain the required temperature, causing $18,000 in spoiled inventory. The sales contract contains no written warranty.
ColdStart has two implied warranty claims. First, the implied warranty of merchantability - the refrigeration unit is not fit for its ordinary purpose (keeping food cold). Second, the implied warranty of fitness for a particular purpose - the supplier knew the unit was needed for seafood storage and ColdStart relied on their expertise. Both warranties were breached. ColdStart can recover the value of the spoiled inventory plus any consequential losses flowing from the failure.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.
Sample Clause Language
Implied Warranty Disclaimer (UCC-compliant)Watch Out For
Implied warranty disclaimers that are not conspicuous
Under the UCC, a disclaimer is only effective if it is conspicuous - meaning a reasonable person would notice it. A disclaimer buried in 8-point gray text on the last page of a 40-page contract may not be enforceable. Use bold type, all caps, or a separate signature block for your disclaimer.Assuming "as-is" always works
"As-is" language is effective under the UCC but must still be conspicuous. In some states, "as-is" clauses in consumer sales are limited or void for consumer protection reasons. Know your customer - B2B "as-is" disclaimers are generally more enforceable than B2C ones.Implied warranties in software and SaaS
Courts are split on whether packaged software is a "good" subject to the UCC or a service subject to common law. SaaS agreements are more likely treated as services. Either way, an implied warranty of workmanlike performance or fitness may arise. Software vendors should include clear disclaimers regardless.Don't let implied warranty deadlines catch you off guard
Key dates tied to implied warrantys - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Include a conspicuous, specific disclaimer in your sales and service agreements
If you sell goods or provide services, include an express warranty disclaimer that names merchantability and fitness for a particular purpose by name, uses conspicuous formatting, and is placed where a buyer will see it. This limits your exposure to warranty claims.Offer a limited express warranty instead of relying on implied warranties
Rather than leaving implied warranties in place, offer a defined limited warranty - for example, 90 days against defects in materials and workmanship. This sets clear expectations and, when properly drafted, replaces the less predictable implied warranties.Frequently Asked Questions
Do implied warranties apply to used goods?
The implied warranty of merchantability applies to used goods sold by merchants, but the standard is lower - the goods must be fit for ordinary use given their age and condition. Sellers can disclaim this warranty using "as-is" language even more easily with used goods.
Can a buyer waive implied warranties before purchasing?
Yes. A buyer can waive implied warranties by signing a contract that contains a conspicuous and properly worded disclaimer. Both parties must agree - a seller cannot unilaterally strip implied warranties through conduct alone.
Do implied warranties apply to real estate?
Real estate is generally not covered by UCC Article 2 (which covers goods). However, many states impose an implied warranty of habitability for residential properties and an implied warranty of good workmanship for new home construction. These are separate from UCC warranties.
How long does an implied warranty last?
The UCC does not set a specific duration for implied warranties. The statute of limitations for UCC warranty claims is four years from the date of sale (or from when the breach was discovered in some cases). Express warranty terms can shorten this if done properly.
