The Surprise
Token-based pricing looks cheap per call. In production, agent calls compound: per interaction × per-user × per-day. Monthly bills 10× budget become common without controls.
Budget Alerts
Set budget thresholds per agent, team, business unit. Alert at 50%, 80%, 100%. Auto-throttle at 110%. Alerting cycles in finance don’t match AI cost accrual; automate the response.
Quotas
Per-user quotas (max agent calls per day). Per-agent quotas (max conversations per hour). Soft limits with escalation before hard limits. Users learn to use agents efficiently when they have visible budget.
Outcome Pricing Alignment
HubSpot’s outcome-based pricing (April 2026) aligns spend with value. Even if your vendor doesn’t, internal outcome tracking does. Per-resolved-case or per-qualified-lead cost frames the right procurement conversation.
