Final answer:
The Percentage-of-Completion Method is the accounting practice of recognizing revenue as a long-term project progresses, reflecting financial performance before the project is fully complete.
Step-by-step explanation:

Unlike other accounting methods, this approach enables businesses to record revenue and expenses related to long-term projects progressively as the project moves forward. It offers a more accurate reflection of the financial progress and performance of a project before its completion.
