WHAT IT DOES

What servicetitan_post_invoice does on ServiceTitan MCP Server

RISK

Why servicetitan_post_invoice is rated Medium

Posting an invoice makes it official/finalized in the system, which is a significant write operation that changes the invoice's state. While it doesn't move money directly, it commits a financial document that triggers billing obligations. It's reversible in principle (invoices can sometimes be voided), so Destructive is not the best fit, but it's a high-severity Write due to financial implications.
