See every featurePurpose-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.
Shopify's B2B checkout includes a purchase order field, but cannot make it required or check the format buyers enter. PO Number Validator adds that control. Set your rules once, and every B2B buyer must enter a PO number matching your format before placing an order. Validation runs server-side, so it applies to every checkout type.
