A Warranty for Custom Work clause guarantees that work created specifically for the client (such as bespoke software, design, construction, or manufacturing) will meet agreed specifications, be free from defects in materials and workmanship, and be suitable for its intended purpose. Unlike off-the-shelf products, custom work warranties must account for the collaborative nature of the project—the client often provides input, feedback, and requirements that shape the final product. The clause defines the warranty period (how long after delivery the warranty applies), the scope of coverage (what defects are included), and remedies (repair, replacement, or refund). This matters because custom work is typically non-returnable and expensive, so the warranty is the primary protection against receiving substandard or unsuitable deliverables.
The liability implications are substantial: custom work warranties interact directly with professional liability, product liability, and general liability insurance. The clause should clearly distinguish between defects caused by the vendor (covered by warranty) and defects caused by client misuse, failure to follow instructions, or changes to specifications (not covered). It should also address the client's responsibility to inspect and report defects within a specified timeframe—failure to do so may waive warranty rights. The warranty should be balanced: too broad and the vendor faces unlimited liability; too narrow and the client has inadequate protection.
As a client, obtain detailed written specifications and have the vendor sign off on them before work begins—this prevents disputes about what "custom work" actually means. Establish clear inspection and acceptance procedures, including a defined period (typically 10-30 days) to identify and report defects before the warranty period begins. Ensure the warranty covers both defects in workmanship and failures to meet specifications, and negotiate a reasonable remedy period (typically 30-90 days for corrections). As a vendor, document all client-provided requirements, approvals, and change orders in writing, and include language limiting warranty to defects arising from your work, not from client-provided materials or specifications. Verify your liability insurance covers the warranty obligations and any indemnification you're accepting.
