Cash Flow — Last 6 Months
Why Nano Fi
Never lose track of a payment again. Know exactly what's owed and when — with automated reminders and status at a glance.
Visualize your financial health at a glance. Spot trends before they become problems with real-time cash flow charts.
AI scans your invoice history and flags slow-payment patterns 3–4 weeks early — so you can act before the cash gap, not after.
How It Works
Sign up free in under 2 minutes — no credit card, no accountant needed. Add your first invoice and you're live.
Every invoice, payment, and overdue amount updates instantly. Your cash position is always one glance away.
AI detects slow-payment patterns and seasonal dips weeks in advance. You get the warning — not the surprise.

Testimonials
“Nano Fi replaced my spreadsheet nightmare. I know exactly what I'm owed before my morning coffee. Saves me at least 3 hours a week.”
Sara K.
Brand Designer, Freelance
“The cash flow dashboard alone is worth it. I caught a slow month coming three weeks out and lined up two new projects before the gap hit.”
Marcus T.
Dev Agency Owner
“I track 7 active clients without a single spreadsheet. Simple, fast, no bloat — exactly what a one-person shop needs.”

FAQ
Do I need a credit card to start?
No. The free plan is completely free — no card required. You only need a card if you upgrade to Pro or Business.
How is my financial data protected?
All data is encrypted in transit and at rest using 256-bit AES encryption. We never sell your data or share it with third parties.
What happens when I hit the 5-invoice limit?
You'll see a warning before you hit the cap. Upgrade to Pro at any time for unlimited invoices — no data is ever lost during the upgrade.
How does the AI actually work?
Nano Fi analyzes your invoice and payment history to detect patterns: slow payers, seasonal revenue dips, and average days-to-pay. It surfaces warnings automatically — no setup or configuration required.
Can I export my data?
Yes. Pro and Business plans include CSV and PDF export. Your data is always portable and yours.
Is there a mobile app?
The web app is fully responsive and works great on mobile. A dedicated iOS/Android app is on our roadmap.
