A cash flow projection primarily helps a contractor:

解析

A cash flow projection lays expected receipts against expected disbursements week by week, so a shortfall is visible before it arrives and a line of credit or a change in billing can be arranged in time. Markup comes from the overhead rate and the target margin, not from a cash schedule. Work in progress is valued from job-cost records against the contract amounts. Depreciation follows the asset's cost and schedule and is a tax and book calculation, with no cash timing in it at all.
