13-Week Rolling Cash Flow Forecast — Excel Template (Built by an FCA)

Description
A weekly cash flow forecasting tool built to investment-banking and Big Four model standards. Designed for finance professionals who need to produce a defensible 13-week cash bridge without spending two days re-engineering the workbook every time a new engagement starts. The model is configuration-driven — new cash inflow or outflow categories require one row in an input sheet, no formula edits, no hidden mappings to maintain.

What's inside (7 sheets): README with one-page setup guide and colour-coding legend; Assumptions sheet with four input cells for company name, currency, forecast start date, opening cash balance, and minimum-cash threshold; Inflows sheet for customer collections, financing draws, and refunds with date-driven auto-bucketing into 13 week buckets; Outflows sheet for vendor payments, capex, tax payments, and debt service using the same date-driven logic; Recurring sheet handling payroll, rent, software, utilities, and EMIs with five frequency options (Weekly, Biweekly, Monthly, Quarterly, One-time) processed by a single robust formula; Forecast sheet with the 13-week cash bridge pulling categorised inflows and outflows via SUMIFS, with conditional formatting that fires red fill when closing cash drops below threshold; Dashboard with eight live KPIs and a closing-cash trajectory line chart.

Why it's different: industry-standard colour coding (blue inputs, black formulas, green cross-sheet links) following the same conventions used in investment banking and Big Four audit models. 1,490 formulas, all recalculated and audited at release — zero hash-REF, hash-DIV-by-zero, hash-VALUE errors. No macros, no add-ins; opens in Excel desktop, Excel Online, Google Sheets via auto-conversion, and LibreOffice Calc. Jurisdiction-neutral with no country-specific tax rules embedded — buyer chooses categories.
