Cancellation
To avoid being charged for a renewed period, users must cancel the applicable paid service or terminate their Labelbox account before the end of the recurring term. Downgrades to a lower plan take effect at the beginning of the next billing cycle (typically the 1st of the next month). Labelbox generally does not offer prorated refunds for any portion of the subscription fee paid for the then-current subscription period if a service is terminated early. For Enterprise plans, cancellation requires contacting Labelbox sales.
For Starter Cloud, accounts remain active until the end of the paid billing period after cancellation; for Enterprise, access to entitlements expires if the contract is not renewed or replaced before it ends.
Commitment
Enterprise plans typically require a minimum spend commitment. A "Redline threshold estimate is $50k" has been noted, which may indicate a minimum contract value for enterprise-level negotiations.
✓
Specific minimum commitment periods for Starter Cloud are not explicitly detailed beyond the monthly billing cycle, but annual contracts are common for enterprise solutions.
