Mastering the 13-Week Cash Flow Forecast: Operational Liquidity Management - Guide to Building, Analyzing, and Acting on Weekly Cash Flow Forecasts for Small and Midsize Businesses

Most businesses know they have a cash problem only after it's too late. A 13-week rolling cash flow forecast changes that. It gives business owners, CFOs, and financial advisors a clear, week-by-week picture of where cash is coming from, where it is going, and — critically — what to do when a problem appears on the horizon. Mastering the 13-Week Cash Flow Forecast is a practical, hands-on tutorial built from real advisory work. It walks you through the entire process, from the very first data request to the weekly report you deliver to management. You will learn how to: Collect and classify transaction data using a structured categorization system Build assumptions for every line item — from fixed payroll and loan schedules to irregular and one-off cash events Construct a bottom-up weekly forecast driven by receivables aging, collection curves, payroll timing, and tax calendars Validate your model against historical data before presenting it to anyone Read the output: spot deficit weeks, concentration risks, and early warning signs of a liquidity problem Analyze whether a cash problem is temporary or structural — and recommend the right corrective action Present findings clearly to management without creating panic Run scenario analysis to show what happens if conditions change This is not about theory. Every chapter follows the sequence a practitioner uses in the field — with detailed guidance on data collection, assumption-building, client communication, model validation, and weekly reporting. Who this book is for: Financial consultants, accountants, management accountants, in-house CFOs, and finance managers who advise or manage SMEs and need a repeatable, professional-grade cash forecasting process. Build the forecast. Find the problems. Fix them before they become a crisis.
