Spend Control for Customer Onboarding Agents
Onboarding agents run verification, provisioning, and welcome flows — each with paid API calls. At signup volume, per-onboarding costs compound.
Where onboarding agents spend
Identity verification APIs per new customer.
Provisioning tool calls per account.
LLM inference for welcome and triage flows.
Email and notification APIs per touch.
The failure modes
A verification retry loop multiplies per-check charges.
A provisioning bug loops against paid tools.
Signup spikes (launch, campaign) hit overage tiers.
Which rules to start with
Per-onboarding cost cap.
Velocity limit on verification retries.
Merchant allowlist for approved verification vendors.
