B2B PO Guard — Require PO

Free: PO format preview. Upgrade for deposits + review routing (Pro) / Plus payment hiding (Advanced). Purpose-built for what native B2B terms don't check: PO number format, prefix, regex, and uniqueness rules, previewed live before you publish. Set deposit percentage guardrails and route orders above a threshold for manual review and approval, with approver email alerts. Works alongside native Net Terms - D2C and no-company checkouts stay untouched.
