Unilateral changes to the terms

Typical wording

The supplier may change these terms. Changes are notified on the website and take effect thirty (30) days after publication.

What it means

The other party can change the agreement as it goes, and you are treated as having accepted the change if you keep using the service.

Common practice

A right to change is common for standardised services, but material changes are normally notified directly and give a right to terminate at no cost.

What to look for

• Are you notified directly, or only through a website?
• Can you terminate at no cost on changes you do not accept?
• Can price and scope be changed on the same basis?
• Is there a distinction between minor and material changes?
