Abstract: Systems and methods are described for providing an item resolution service. Users may add entries to an electronic list (e.g., a grocery list), via voice input, text message, or other input to a mobile, desktop, or web application. The list entries may contain general descriptions (e.g., “milk,” “eggs,” “bread,” etc.) that can be associated with various items available from various suppliers. The item resolution service may determine, for individual list entries, a specific item based on factors such as the user who created the entry, the order or browsing history of that user, the geographic location of another user (e.g., a user who is currently located at a particular grocery store), or other factors. The list entries may thus be converted to items in an electronic shopping cart, which may then be ordered for delivery, in-store pickup, or presented in a manner that facilitates acquiring the items in person.
