Warranty Period

Definition

The window of time during which a seller, contractor, or service provider guarantees their work and agrees to fix defects at no additional cost. After the warranty period expires, the buyer assumes the risk. Warranty periods vary widely — from 30 days for simple services to lifetime for some manufactured goods.

In Practice

A web developer builds your e-commerce site and includes a 90-day warranty period. On day 45, the checkout process breaks after a browser update. The developer fixes it at no cost — it's within warranty. On day 120, the search function breaks. Now it's out of warranty, and the developer quotes $2,000 to fix it. Had you negotiated a 6-month warranty, that repair would have been covered. For software, push for at least 6 months. For construction, 1–2 years is standard.

Frequently asked questions about warranty period

It depends on what's being delivered. Software and web development: 60–180 days is typical, 6 months is strong. Construction: 1–2 years is standard (some jurisdictions mandate minimum periods). Manufactured goods: 1–5 years depending on the product. Professional services: 30–90 days from delivery. The warranty should be long enough to discover latent defects but not so long that it creates indefinite liability.
