Warranty period

Definition

A warranty period is the agreed window after delivery within which the supplier remains obliged to repair or replace defective performance, usually free of charge. A contractual warranty supplements the buyer's statutory conformity rights, which under Dutch law flow from article 7:17 BW; a warranty cannot generally curtail those mandatory rights for consumers. The period's start, scope and exclusions should be defined precisely to avoid disputes.

Example

A two-year warranty period obliges the manufacturer to replace components that fail under normal use within that time.

Why this is a business risk

Warranty periods expire quietly unless someone is watching the calendar. Buyers who fail to report defects before the period ends lose contractual protection and may face full repair costs. On the supplier side, an imprecisely defined start date or ambiguous scope leads to warranty claims long after the period was intended to close.

How to manage it

• Record the warranty start date and end date as trackable milestones at the moment the contract or acceptance protocol is signed.
• Set a reminder thirty to sixty days before expiry so any latent defects can be inspected and reported before protection ends.
• Define clearly what voids the warranty -- misuse, unauthorised modification, normal wear -- to prevent disputes about exclusions.
• Align the warranty period start with the acceptance date rather than the delivery date, since the clock should only run after conforming delivery is confirmed.
• Keep warranty claims and remedies in writing so there is a clear record of what was reported, fixed and when.
