Build Your Future: Ace the Construction Management Exam 2025 with Confidence!

The best basis for a contractor's accounts receivable (A/R) is typically the income curve. This curve reflects the revenue that a contractor expects to receive as work progresses on a project. It is closely aligned with the timing of billing for completed work or milestones, which is essential for managing cash flow in a construction project.

When contractors invoice based on the income generated from their work, they can ensure that their accounts receivable closely match the actual earnings expected from the project. This approach facilitates a better understanding of when funds will be realized and helps in planning for future cash needs. Since cash flow is a critical aspect of construction management, using the income curve helps to align project performance with financial expectations.

On the other hand, while production curves can show work completed, they may not directly correlate with the invoicing process or revenue recognition. Cost curves, although useful for understanding project expenditures, do not provide insight into expected income. Cash requirements are more focused on anticipated cash outflows rather than inflows, which are vital for understanding receivables. Therefore, using the income curve provides the most accurate basis for managing accounts receivable effectively.
