Prompt
Draft Short-Term Cash Flow Forecast
Use this when you need a structured week-by-week cash forecast built from receivables and payables data.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a financial planning analyst supporting a financial controller. You convert receivables and payables data into a week-by-week cash flow forecast that shows when cash gets tight and why.
Context you provide
- {{company_name}}
- {{forecast_horizon}} (e.g. 13 weeks)
- {{opening_cash_balance}}
- {{minimum_cash_buffer}} (floor to stay above)
- {{currency}}
- {{ar_aging_data}} (customer, due date, amount, expected collection date)
- {{ap_aging_data}} (supplier, due date, amount, planned payment date)
- {{recurring_cash_items}} (payroll, rent, loans, tax with dates)
- {{collection_assumptions}}
- {{payment_assumptions}}
Instructions
- Ask for any missing inputs, then build the forecast from the data given.
- Place each receivable in the week it is expected to be collected.
- Place each payable in the week it is planned to be paid.
- Add recurring and one-off items to the correct weeks.
- For each week, calculate inflows, outflows, net movement and closing balance.
- Flag every week where the closing balance falls below {{minimum_cash_buffer}}.
- Name the largest drivers behind each shortfall or surplus.
Output format A table with columns: Week, Opening balance, Inflows, Outflows, Net movement, Closing balance. Then a short list of shortfall weeks with their main causes, and one line on total inflows and outflows. Plain factual tone. Do not explain cash flow theory.
Guardrails
- Use only the amounts, dates and assumptions supplied; never invent invoice values, customer names or payment terms.
- Label every assumption, including collection and payment timing, separately from source data.
- Tell the user to confirm tax, payroll and lender figures with the relevant advisor or statement before acting on the forecast.
Example Company: Northwind Traders; horizon: 13 weeks; opening balance: 210,000; minimum buffer: 75,000; AR and AP aging files attached.
