US Patent 11769163 Service call-ahead system and method

Examples of service call-ahead systems and methods are disclosed. In one example implementation according to aspects of the present disclosure, a service order management system includes a processing device, a servicer device, and a memory device. The service order management system is enabled at least to prompt a servicer to modify an initial estimated time of arrival (ETA) and notify a customer of the modified ETA of a servicer at a service destination. Prompting the servicer to modify the initial ETA enables the processing device to notify the customer of the modified ETA, which is more accurate than the initial ETA. Other service call-ahead and notification techniques are also disclosed.
