         If you have configured required information fields in your store’s Extra Fields settings for Company accounts or Company users, you must include the field’s name and value in the `extraFields` array of the request body.

+        ### Pending Company Accounts
+
+        If your store uses [Independent Companies behavior](https://support.bigcommerce.com/s/article/Companies-and-Customer-Groups), buyers with a pending Company account cannot log in to the B2C version of the Buyer Portal or view previous orders until you have approved or rejected their Company application. Depending on your Company management setting configurations, they may also be restricted from viewing products and placing orders.
+
+        When you approve an application, the buyer can log in to the B2B version of the Buyer Portal and view previous orders. Rejecting an application restores their access to the B2C version of the Buyer Portal.
+
+        For stores using legacy Dependent Companies behavior, buyers with a pending Company account can still log in to the Buyer Portal and view their orders before you have processed their application.
+
+        See [Companies (Help Center)](https://support.bigcommerce.com/s/article/B2B-Edition-User-Guide-Company-and-Customer-Functions) to learn more about the settings and buyer experience for pending Company accounts.
