Quillfy Cash Flow Stress Test

You know your revenue. You know your expenses. But do you know what happens to your cash in Week 8 when your biggest customer pays 14 days late and payroll still lands on Friday?

Almost no small business owner does — until it happens.

The Quillfy Cash Flow Stress Test is a free, 3-minute tool that projects your cash position 13 weeks into the future, then throws six real-world punches at it: falling revenue, delayed payments, rising costs, lost customers. It shows you where your cash bottoms out, which week you breach your minimum reserve, and which expense is silently eating your business alive.

It's not accounting software. It's not a forecast you'll never update. It's a stress test — the same logic banks use on themselves, scaled down to fit your business and your attention span.

Run it once. Run it monthly. Run it before you sign that lease, hire that staff, or take that loan. Every time, you'll walk away knowing one thing clearly:

How long you have — and what to do about it.

Tagline options:

• "Know your runway before you need it."

• "Find out in 3 minutes what your bank statement won't tell you."

• "Stress-test your cash. Sleep better tonight."

• "The 3-minute check that could save your business."
