Approvers burn time on expense reports that a policy check could settle in seconds — and real violations slip through because nobody reads every receipt. This recipe collects submissions and receipts from Gmail, matches card transactions to reported lines when the payment account is connected, and checks every line against the policy document: limits, categories, receipt present, date rules. Violations are flagged with the exact policy clause and the amount at stake — never a bare rejection. Roll-ups give per-employee totals and outliers, and the approval package separates clean lines marked auto-approve-ready from itemized violations, so approvers spend attention only where judgment is needed. Nothing forwards, posts, or approves unreviewed. Idempotent per report + window: reruns update the audit in place, never duplicate a flag or re-audit a line already cleared.
