Real-time management of inventory transfers and related user interfaces

An inventory control system, comprising:

• a database storing data for a plurality of product items;
• a processor;
• and
• a memory storing computer-executable instructions that, when executed by the processor, are to cause the processor to:
• receive, via a graphical user interface on a customer computing device over a network, a user input including selection of a product, the graphical user interface comprising a webpage associated with an online storefront;
• determine, based on inventory data for at least one possible pick-up location for the product retrieved via requests to an inventory API associated with the at least one possible pick-up location, that there is insufficient available inventory of the product at the at least one possible pick-up location;
• in response to determining that there is insufficient available inventory of the product at the at least one possible pick-up location:
• select, based on inventory tracking data for the product, a first inventory location having available inventory of the product;
• obtain location tracking data associated with one or more inventory transfer vehicles indicating real-time locations of the one or more inventory transfer vehicles;
• determine, based on the first inventory location, the at least one possible pick-up location, and the real-time locations of the one or more inventory transfer vehicles, an inventory transfer time for transferring inventory of the product from the first inventory location to the at least one possible pick-up location, the determining including querying a transfer service over the network for the transfer time data;
• and
• determine an earliest time of availability of a first quantity of the product at the at least one possible pick-up location based on the inventory transfer time, and
• cause the webpage associated with the online storefront to be updated in real-time to display, on the customer computing device, local pick-up availability data representing availability of the first quantity of the product at the at least one possible pick-up location based on the determined earliest time of availability transmitted over the network;
• receive, via the customer computing device over the network, a request to process an order for the product for pick-up at a first one of the at least one possible pick-up location;
• and
• transmit, to a merchant system over the network, a request to transfer inventory of the product to the first pick-up location.

A computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving, via a graphical user interface on a customer computing device over a network, a user input including selection of a product, the graphical user interface comprising a webpage associated with an online storefront;
• determining, based on inventory data for at least one possible pick-up location for the product retrieved via requests to an inventory API associated with the at least one possible pick-up location, that there is insufficient available inventory of the product at the at least one possible pick-up location;
• in response to determining that there is insufficient available inventory of the product at the at least one possible pick-up location:
• selecting, based on inventory tracking data for the product, a first inventory location having available inventory of the product;
• obtaining location tracking data associated with one or more inventory transfer vehicles indicating real-time locations of the one or more inventory transfer vehicles;
• determining, based on the first inventory location, the at least one possible pick-up location, and the real-time locations of the one or more inventory transfer vehicles, an inventory transfer time for transferring inventory of the product from the first inventory location to the at least one possible pick-up location, the determining including querying a transfer service over the network for the transfer time data;
• and
• determining an earliest time of availability of a first quantity of the product at the at least one possible pick-up location based on the inventory transfer time, and
• causing the webpage associated with the online storefront to be updated in real-time to display local pick-up availability data representing availability of the first quantity of the product at the at least one possible pick-up location based on the determined earliest time of availability transmitted over the network;
• receiving, via the customer computing device over the network, a request to process an order for the product for pick-up at a first one of the at least one possible pick-up location;
