Build a 4-Week Cash Flow Forecast from Invoices and Bills

I'm going to give you two data sets from my accounting software. The first is my Accounts Receivable — open invoices with due dates and amounts. The second is my Accounts Payable — bills I owe with due dates and amounts.

My current bank balance is: [insert your balance]

My recurring fixed weekly costs not listed in the AP data are:
- Rent: [amount, due date]
- Payroll: [amount, weekly or bi-weekly]
- Software subscriptions: [amount]
- Any other fixed costs: [amount]

Using this data, build me a 4-week rolling cash flow forecast. Show me:
1. A week-by-week table with: Cash In, Cash Out, Net Cash Movement, and Ending Bank Balance.
2. A plain-English risk summary of no more than 5 sentences. Flag any week where my ending balance drops below [insert your minimum comfortable balance, e.g. $5,000].
3. A list of any invoices more than 14 days overdue that I should follow up on this week.

Treat invoices as likely to be paid within 7 days after their due date unless they are already overdue. Treat all bills as paying on their due date. Do not assume any income beyond what I have provided.
