The Number One Killer of Businesses Isn’t Lack of Profit—It’s Lack of Cash.

You closed a big deal. Your P&L looks great. But payroll is on Friday, supplier invoices are due, and that client just asked for a 30-day extension. Suddenly, you’re scrambling.

Building a reliable 13-week rolling cash flow forecast in Excel usually means dealing with broken formulas, linked sheets, and hours of manual data entry every Monday morning. One wrong cell, and your entire projection is useless.

It’s time to ditch the fragile spreadsheets and take control of your working capital with our dynamic 13-Week Cash Flow Forecast tool.

What Makes This the Ultimate Cash Management Tool?

Built for financial controllers, founders, and bookkeepers who need absolute clarity on their liquidity.

• True Rolling Forecast Logic: Easily slide your dates forward. As week one ends, simply add week 14. You always maintain a precise, 13-week forward-looking view of your cash position without rebuilding the model.
• Automated Inflow & Outflow Categorization: Instantly separate your operating, investing, and financing activities. See exactly where cash is coming from and where it’s bleeding out.
• Visual Shortfall Alerts: No more squinting at rows of numbers. The dashboard uses smart, color-coded indicators to instantly show you which specific weeks you are projected to go negative—giving you weeks of lead time to secure a credit line or delay expenses.
• Scenario Modeling on the Fly: “What if we delay paying this vendor?” or “What if that invoice comes in on the 15th instead of the 30th?” Update one input and watch the entire 13-week trajectory recalculate instantly.
• One-Click Executive Reporting: Need to show this to your bank for a line of credit, or to your investors? Export a perfectly formatted, professional PDF report with your charts and summaries in one click.

Frequently Asked Questions

Why 13 weeks specifically?

The 13-week cash flow forecast is the gold standard in corporate finance and banking. It provides a short-term, highly actionable view of liquidity that monthly forecasts simply cannot offer. It bridges the gap between daily cash management and long-term budgeting.

Does this tool connect to my bank account?

No, and that is by design. Direct bank connections often pull in noisy, uncategorized data. This tool is built for forecasting—inputting your expected cash movements so you can model the future, not just report the past. It gives you much cleaner, more accurate projections.

Can I save different scenarios?

Yes. Using your browser’s local database, you can save, name, and load unlimited scenarios (e.g., “Base Case,” “Worst Case Delayed Receivables”) without needing to create an account or save files to your hard drive.

Is my financial data secure?

Absolutely. This is a standalone HTML application. It does not send, store, or transmit your data to any external server. Your sensitive financial projections stay entirely on your local machine.
