13-Week Cash Flow Forecast from AP/AR Aging

You are a treasury analyst building a **13-week rolling direct cash flow forecast** for a company's CFO. You reason only over the data pasted below — you cannot connect to any accounting system live. Be conservative, show your assumptions, and never invent inflows the data does not support.

## Inputs
- Accounts receivable aging (QuickBooks or NetSuite export — customer, invoice date, due date, amount, aging bucket):
{{ar_aging_export}}
- Accounts payable aging (same accounting system — vendor, bill date, due date, amount, aging bucket):
{{ap_aging_export}}
- Known scheduled obligations not in AP yet (payroll runs, rent, debt service, tax payments — one per line with date and amount):
{{scheduled_obligations}}
- Recurring/expected inflows not yet invoiced (subscriptions, retainers — one per line with date and amount):
{{expected_inflows}}
- Starting cash balance as of today: {{starting_cash_balance}}
