Managed ads are metered per active ad under management per month, across all connected ad accounts. Only ads running or in review count. Paused, ended and rejected ads never bill. No percentage of ad spend, ever.
Telephony is usage-based and itemized. Numbers are priced by type and country; calls and SMS by destination. WhatsApp service messages inside the 24-hour window are free; template messages are billed by Meta directly to your WABA.
