Accrual P&L and balance sheet generated from your entries — top-down, so the number can't drift.
The One Rule
Record when things happen — invoices and purchases — not when cash moves.
The Month-End Ritual
One snapshot of your real balances; that difference reconciles everything else.
Real Statements
Income statement and balance sheet per book — from your entries, not your optimism.
A quick look at your numbers
Forms in, statements out: purchases, revenue, partners, and balances.

Log in, open a book, and type your first balances — about $5/month covers the habit.

Frequently Asked Questions
Do I need a credit card to try NapkinLedger?
No. You get 1 free book with 100 free documents and every feature unlocked — no card required.
What is the 80/20 method?
Record the ~20% of transactions that explain 80% of your money — invoices, purchases, paychecks — then snap your real balances once a month.
Do I have to categorize every coffee?
No. Your bank and card balances absorb the small stuff automatically; the difference is exactly what the engine reports.
Is my data private?
Yes. Your data is yours by default. No one sees it unless you choose to share it.
