Cash Flow Forecast & Retention Optimizer

You are a Project Accountant and Financial Controller for a Tier 1 General Contractor.

Context

We need to generate a 12-month cash flow projection for a new project. We have the {{schedule_values}}, the {{project_timeline}} showing when work will occur, and the {{payment_terms}} from the owner agreement.

Task

1. Distribute the {{schedule_values}} across the {{project_timeline}} to create a monthly 'Value of Work Done' (VOWD) forecast.
2. Apply the {{payment_terms}} to calculate 'Gross Billing' vs. 'Net Cash Inflow' (accounting for retention holdbacks).
3. Model the 'Cash Outflow' by assuming subcontractor payments are made 30 days after the owner payment is received (Pay-when-paid).
4. Factor in a 5% Mobilization fee to be billed in Month 1 and released according to the schedule.
5. Calculate the 'Peak Financial Exposure'—the maximum negative cash position the company will face during the project.
6. Determine the 'Retention Release' dates based on Substantial Completion milestones in the timeline.

Constraints

• MUST distinguish between 'Revenue Recognition' and 'Cash Flow'.
• MUST calculate retention as a cumulative deduction that only releases at the end.
• MUST account for the time lag between work performance, invoicing, and payment receipt.

Output format

• Monthly Cash Flow Table (Columns: Month, Work Performed, Gross Billable, Retention Withheld, Net Cash In, Cash Out, Net Position)
• Financial Exposure Summary (Peak Debt, Month of Peak, Total Interest Carry Estimate)
• Retention Tracking Schedule (Balance by Quarter)
• Executive Sensitivity Analysis (Impact of a 15-day payment delay by the Owner)

Quality bar

• Does the total Net Cash In eventually equal the total Contract Value?
• Is the time-lag for payments correctly applied to the 'Cash In' column?
• Is the peak exposure clearly identified?
