You can downgrade your organization to the free plan at any time.
Downgrading to free does not affect your subscriptions for other paid features and products. If you want to cease all of your paid subscriptions on GitHub, you must downgrade each paid subscription separately.
Warnings:
Only organization members with the owner or billing manager role can access or change billing settings for your organization.
Plan changes take effect immediately. Make sure you clone your private repositories before you downgrade, or you won't be able to access them without upgrading to paid again.
