The core idea: a system of record

A system of record is the place you go to find out what actually happened — not a guess, not a summary, the real thing. That’s what finzu tries to be for your money: somewhere you can look up any transaction, on any account, and trust that what you see is real.

Most finance apps optimize for a nice-looking number on a dashboard. Finzu optimizes for that number being right, even when right means showing you something is unresolved. Its core rule: an assumption never poses as a fact. If finzu doesn’t actually know your account’s starting balance, it won’t quietly invent one and display it like it knows. If a balance doesn’t add up, it says so — it doesn’t smooth the number over so the app looks clean.

What this buys you

A dashboard you can act on. When finzu says a category total is $340, that number traces back to real transactions from real statements, not an estimate. When something looks off — a gap, a balance that doesn’t follow from the last one — finzu surfaces it instead of hiding it, so you can go fix the actual problem instead of wondering if the app is even right.

What this costs you

Occasionally, seeing “this needs your attention” instead of a clean number. That’s the trade finzu makes on purpose: a flag you can resolve beats a number you can’t trust.
