Seven questions to ask before you pay for any cash-flow tool
Ours and anyone else's. Here are our answers.
- 1Does it need a bank or accounting login?
- No. No account, no bank login, no upload. The file stays with you.
- 2Is it a subscription?
- No. One payment.
- 3Does it work week by week, not only month by month?
- Yes. 13 weeks, with a weekly routine.
- 4Can you test a decision before you make it?
- Yes. The simulator, and the SCENARIO TEST tab (base, bear, bull, plus a new monthly cost).
- 5Does it tell you when your assumptions keep missing?
- The VARIANCE LOG flags any line that misses in the same direction three weeks running.
- 6Where do your numbers go?
- Nowhere on their own. They leave the file only when you paste an AI prompt yourself, or share them with me in a Build Session you booked.
- 7What if it is not for you?
- 14-day refund promise, for any reason. And if you already update a free template every week, keep it.
If you already keep a 13-week forecast current, you may not need this. If you keep meaning to, start with the free starter.
The 14-day refund promise
14-day refund promise. Ask within 14 days of buying and you get a full refund, for any reason. Link processes it. Write to hello@getcfobrain.com with the word "refund".
There is no free trial. The simulator and the starter are free with no time limit, so you can try the approach before you buy.
Payment and delivery
You pay on Link's secure checkout. You get the receipt by email, and your download on the download page. Link is the legal seller and sends the receipt, with any VAT or sales tax shown.
Payment is handled by Link. We never see your card.
Businesses: the receipt shows any VAT or sales tax. Questions before you buy: write to hello@getcfobrain.com. See the terms and the refund page.
Questions about the price
How is this different from the free 13-week templates online?
If you already update a free template every week, keep it. The free starter from CFO Brain is one tab of this workbook. What the full workbook adds: a cash floor tied to a status message, a Friday variance log that flags a line missing in the same direction three weeks running, a scenario test for a hire or a new monthly cost, a working-capital view, prompts that already know your numbers, and a 15-minute routine to keep it current.
My accounting software already has a cash-flow forecast.
Some do, and if you use yours every week, keep it. What this adds: you plan every line yourself for 13 weeks, you set a cash floor and see the week you would cross it, a Friday variance log flags assumptions that keep missing, and a scenario test shows what a hire does in a bad quarter. No subscription, no bank connection.
Do my numbers leave my computer?
No. There is no account, no bank login and no upload. The workbook is a file that stays with you, or in your own Google Drive or iCloud if you open it there. The simulator on this site runs in your browser and never sends your numbers anywhere. The only time numbers leave the file is when you choose to paste an AI prompt into an assistant, or share them with me in a Build Session you booked.
Is this financial, tax or legal advice?
No. CFO Brain is a planning tool. Tax amounts and dates come from you or your accountant; the workbook only shows when the money leaves. Check important decisions with your accountant or tax adviser.
What happens after I pay?
You pay on Link's secure checkout. You get a download page and a receipt by email. If you lose the page, write to hello@getcfobrain.com with your order number and we send you the file. Open the file in your spreadsheet app and start on the START HERE tab.
Do I get a receipt?
Yes. Link is the legal seller and sends the receipt with your order. Any VAT or sales tax is added at checkout, and the checkout shows the final amount before you pay.
What if it is not for me?
14-day refund promise. Ask within 14 days of buying and you get a full refund, for any reason. Link processes it. Write to hello@getcfobrain.com.
Do you offer support and updates?
Questions about using the file: write to hello@getcfobrain.com. We answer within 2 working days. If a formula in the file as delivered gives a wrong result because of a mistake in the file, we fix it and send you the corrected file, for 12 months after your purchase.
Can my bookkeeper use it for my business? Can I use it for several businesses?
Yes for your own business, and your bookkeeper or accountant may open it. One purchase covers one business.
Why does a spreadsheet cost US$149?
Because the work is in the assembly and the habit: 324 checked formulas, a floor tied to a status, a log that flags a pattern, a hire test and a 15-minute routine. If you already keep a 13-week forecast current, you may not need it, and the free starter uses the same weeks-of-cash calculation on one tab. It is one payment, with a 14-day refund promise.
Is there a free trial?
There is no timed trial. The Cash Cliff simulator and the 13-week starter are free with no time limit, so you can try the approach before you buy. The workbook has a 14-day refund promise.
