Checkout Fields for Carrier Account Numbers and PO Numbers
The Opportunity
An app that adds required custom fields in checkout for shipping account numbers, PO numbers, and similar order reference details. It helps merchants collect customer shipping billing info at the right step so orders are not delayed or manually corrected later.
"Customers need to enter UPS/FedEx account numbers and PO numbers, but Shopify checkout/cart limitations make it easy for them to miss or ignore the required fields."
Market Validation
Detailed Analysis
Proposed Solution
Provide configurable checkout or pre-checkout fields with validation, conditional logic, and reminders for shipping account number, carrier selection, and PO number collection.
Target Audience
Shopify merchants selling B2B, wholesale, or any business that ships on customer carrier accounts and requires PO numbers.
Competitive Landscape
Custom Checkout Fields, checkout field apps, product options apps with checkout add-ons
Implementation Notes
Build a checkout or order-information capture app using Shopify-supported extensibility points, with configurable required fields, field validation, conditional display rules, admin alerts, and order metafield/order note storage so merchants can reliably collect carrier account numbers and PO numbers before fulfillment.
