About PO Validator B2B

Blocks checkout without a valid PO number. Prevent invalid B2B orders before they reach your team.

B2B merchants must attach a Purchase Order number to every order, but Shopify provides no native way to enforce this. Buyers skip the PO field or enter invalid data, causing fulfillment delays and ERP mismatches. PO Validator solves this with server-side validation via Shopify Functions. Buyers cannot complete checkout without a valid PO number. Configure rules: required field, min/max length, mandatory prefix, regex patterns, allowed characters, and multilingual error messages.

Listing highlights

  • Server-side checkout validation that buyers cannot skip or bypass
  • Flexible rules: length limits, required prefix, and regex for ERP formats
  • Character rules: whitelist allowed characters and block unwanted spaces
  • Regex rules: validate PO formats against ERP and SAP number patterns
  • Supports EN, DE, FR, and ES error messages out of the box
PO Validator checkout error for invalid PO number format
PO Validator: valid PO numbers required at B2B checkout
PO Validator admin: set required field, length & prefix
PO Validator admin: regex, character & error message rules

Methodology

How to read these signals

Counts are based on Shoplist's latest available public crawl signal dated June 8, 2026.

Shoplist has not yet found reliable public storefront evidence connecting a Shopify store to this app. This does not mean the app has no users. Some apps are new, admin-only, server-side, theme-independent, or otherwise difficult to detect from public storefront signals.

Merchant rows are filtered to public brand profiles with enough public data to link safely. Full workflow, filtering, and monitoring stay behind signup.

Review, pricing, feature, screenshot, and listing-change data come from public Shopify App Store and Shoplist crawl records. Signals can change between crawls.
