What is the primary reason an electrical contracting business should use sequentially numbered work orders and match each one to a corresponding numbered invoice?

By using sequentially numbered work orders and verifying that each one results in a corresponding invoice, an electrical contractor can detect if a technician discards a service record after directly collecting payment from a customer.

You suspect a technician might be performing unrecorded side jobs during normal business hours. Arrange the steps you should take to audit your records and use internal controls to detect if any service calls were completed and discarded without billing the customer.

Match each operational scenario or vulnerability with the specific mechanism of a sequential work order and invoice matching system that addresses it.

An electrical business owner evaluates their dispatch system and identifies a critical vulnerability: technicians could easily pocket cash payments and discard the service paperwork without detection. To effectively close this loophole and verify that every dispatched call is billed, the owner must implement ____ numbered work orders and strictly match each one to a final invoice.

You are designing the 'Standard Operating Procedures' (SOP) for your new electrical service business from the ground up. To construct a comprehensive 'closed-loop' system that prevents technicians from performing unrecorded side work, which specific administrative workflow should you implement?
