What merchants ask before adding the field.
Can I make the trade account number required?
Yes. Each field can be set to required or optional. Required means the customer cannot complete checkout until they enter a valid account number; optional lets non-trade customers check out normally.
Can I validate the format of the account number?
Yes. You can add a regex pattern so only correctly formatted numbers are accepted — for example a fixed prefix, a set length, or letters-and-digits. The check runs as the customer types.
Where does the account number appear in my admin?
On the order. It is saved as a pinned order metafield and the order is auto-tagged, so it is visible on the order page and available in exports, the Admin API, and Shopify Flow.
Does this work with Shopify B2B and company accounts?
Yes. It runs on the Shopify Plus checkout and captures the account number regardless of whether the buyer is a standard customer or a B2B company, so you can layer your own trade reference on top of Shopify B2B.
Is this a payment method or a credit account?
No. Trade Account Checkout is a field-capture extension, not a payment method, processor, or gateway. It records the account reference only. To offer pay-on-account, pair it with Shopify's own manual payment method.
Will it change my existing checkout or payments?
No. It adds a field to the checkout and writes data to the order. Your payment providers, shipping, and the rest of your checkout stay exactly as they are.
