Described herein are systems and techniques for implementing a third-party item tracking and payment system that enables a user to walk out without a manual checkout process. The techniques include receiving user identifying information associated with a payment account and conveying an identifier of the account to a management system of the retailer. Items, as selected by the user, are added to a virtual cart that is checked out automatically when the user exits the store and the third party system communicates the cart contents to the retailer for cost calculation and then instructs payment using the stored payment information without disrupting existing inventory and account management systems.
