Technologies are shown for buyer initiated automatic seller account generation where a buyer client receives an identification of a purchase item, generates an item token corresponding to the purchase item, and provides the item token to a seller client. The seller client authenticates a seller user with an authentication service, such as a biometric authentication service, receives an authentication token corresponding to the seller user, and sends an account creation request with the item token and the authentication token to an account creation service. The account creation service receives the account creation request, sends a user information request to the authentication service with the authentication token and receives seller information for the seller user from the authentication service. The account creation service creates a seller user account using the seller information, commits a purchase transaction for the purchase item, and sends an item purchase confirmation to the buyer client.
