Negative-Option Billing

Negative-option billing is a commercial practice in which a seller begins or continues charging a customer unless the customer actively opts out. The customer's inaction — not cancelling, not returning a product, not responding to a notice — is treated as implicit consent to the charge. This model is used in free-trial-to-paid conversions, continuity plans, subscription boxes, book clubs, and gym memberships.

The practice is not inherently illegal — it is permissible in many jurisdictions when clearly disclosed — but it is frequently abused when disclosure is inadequate, when opt-out mechanisms are difficult to find or use, or when charges begin without sufficient notice. Vulnerable consumers, including those who do not read full terms and conditions, are disproportionately affected.

Regulatory frameworks (including the FTC's Negative Option Rule in the US and similar consumer protection laws in the EU and UK) require clear pre-purchase disclosure of the negative-option feature, the total amount to be charged, how to cancel, and the cancellation deadline for free trials. Violations attract significant enforcement action.
