Profit on paper does not guarantee enough cash at the right time. A 13-week view helps you see timing pressure early and prepare better questions before making a financial decision.
This guide helps you create a plain-language cash flow scenario brief that shows assumptions, timing pressure, decision triggers, and questions for your accountant or adviser.
What you need
- A verified 13-week cash schedule or spreadsheet
- Opening cash, expected receipts, payroll, taxes, debt, recurring expenses, and planned payments
- An owner or finance professional who can verify inputs and decisions
The workflow
1. Keep calculations in the spreadsheet
Use formulas and a reviewed source of truth for money. Give AI summarized, redacted outputs and assumptions, not banking credentials or unchecked transactions.
2. Create explicit scenarios
Build base, downside, and upside cases by changing named assumptions such as collection timing, sales, or a planned expense.
3. Look for timing, not only totals
A profitable period can still have a cash gap. Identify the lowest week, required buffer, and decisions that must happen before it.
4. Use the brief to ask better questions
AI can explain and surface assumptions. Financing, tax, payroll, and major spending decisions need qualified human review.
Copy this working prompt

Return:
1. Plain-language base-case summary
2. Lowest projected cash week in the supplied data

4. Assumptions with the greatest effect
5. Differences among the three scenarios
6. Early warning indicators

Use only provided values. Do not infer credit availability, recommend financing, move payment dates, alter payroll or taxes, or present projections as certain.Run a second-pass review
The first output should not be the final answer. Use this challenge prompt to find weak evidence, hidden assumptions, or avoidable risk.
Audit this brief for arithmetic claims not visible in the supplied summary, hidden assumptions, false certainty, and decisions that require a qualified financial professional.What good looks like
- Every scenario names its assumptions
- Cash timing pressure is visible
- The brief creates questions instead of pretending to advise
Review before you use it
- Was the spreadsheet verified by the responsible person?
- Are taxes, payroll, and debt handled by qualified professionals?
- Are scenario assumptions dated and owned?
Privacy and judgment guardrails
- Remove passwords, payment details, private health information, and confidential customer data before pasting anything into an AI tool.
- Treat the output as a working draft. A person remains responsible for the decision, promise, price, and final send.
- Do not let AI invent customer quotes, financial figures, legal terms, capabilities, deadlines, or proof.
Your next action
Review the brief beside the actual spreadsheet with your bookkeeper, accountant, or finance lead before acting on it.
