Post an official invoice against an active job. GATED behind HOUSECALLPRO_ALLOW_INVOICE env var. Returns an error if not enabled. This action creates a billable customer-facing invoice.
AI agents use generate_job_invoice to commit financial operations through Housecallpro — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Generating an invoice is a financial commitment action — it creates a legally and financially binding document sent to a customer demanding payment. This directly triggers financial obligations and is irreversible once delivered. The tool is gated behind an env var, indicating the authors recognize its elevated risk. This clearly falls under Financial as the most severe applicable category.
