Accounting.
Invisible.

Lives in LINE. No apps. No tables.
Just snap... and live.

iPhone 15 Pro with zFiN Interface

Precision.
Not an accident.

"I built zFiN because business numbers need bank-grade accuracy but chat-like simplicity. Our AI accountant never sleeps. Never makes a typo. And stands by in your LINE, invisible until you need it."
