The prompt
Roll this 13-week cash flow forecast forward one week: [paste forecast]. Apply only these approved changes: [paste]. Keep the assumption visible on every line and give me a change log of what you modified. Do not add new assumptions of your own.What to bring
The 13-week forecast lives in one person's spreadsheet, updated by hand, and every board ask means a late night re-checking which rows are current.
What a good run returns
Week, opening cash, inflows, outflows, closing cash and assumption per row, in a Google Sheet in a Finance Cash Flow Forecast Workspace folder.
Where the free version ends
A prompt runs when you remember to run it, from whatever context you paste, and it forgets the rules between sessions. The Cash Flow Forecast Agent ($19 one-time) installs this as a standing workflow: fixed evidence rules, a saved output in your own Drive every run, fictional-data testing before real work, and hard stops before anything sends, spends or publishes. More detail on the AI cash flow forecasting guide.
