US Patent 11042834 Voice-enabled substitutions with customer notification

A method to provide an order for a user to select goods includes automatically prompting a user via a voice command to collect an item from an order placed by a customer, and in response to receiving the input from an electronic device indicating that the item is unavailable, automatically prompting the user via a voice command to collect a substitute item designated, receiving an input indicating that the substitute item has been collected, followed by electronically notifying the customer that the substitute item has been collected instead of the original item. In another aspect, a voice-enabled click and collect system includes a remote server in communication with a mobile device, configured to prompt a user to collect an item, communicate the item unavailability to the remote server, receive instructions from the remote server, prompt the user to collect the substitute item, and notify the customer.
