Why track balances instead of transactions

Personal finance software mostly agrees on the approach: capture every transaction, sort it into categories, and report on where the money went.

Walleet does the opposite. It records what each account holds and ignores how it got there. That is a real trade with real losses, and it is worth setting out why it is the better one for most people.

Two different questions

Transaction tracking answers "where did my money go?"

Balance tracking answers "how much do I have, and is it growing?"

They sound like the same question and they are not. The first is about behaviour, the second about position. Most people who install a finance app believe they want the first and actually want the second — they want to know whether they are getting ahead.

You can answer the second without answering the first. That is the whole bet.

The diligence problem

Transaction tracking has an adoption curve that people rarely admit to.

Week one is genuinely interesting. You discover what you spend on coffee. Week six, the imports need correcting: merchant names are unreadable, a single shop lands in three categories, transfers between your own accounts appear as income and expense, refunds double-count. Week twelve, you stop correcting, and the reports keep generating — confidently, and wrong.

That last state is worse than not tracking. An abandoned system produces numbers that look authoritative and are not, and you either act on bad data or learn to distrust the whole thing.

The failure is structural, not a lack of discipline. The work is proportional to how much you buy, it never ends, and the reward is a chart most people look at twice.

Balances do not decay

A balance is a fact your bank has already computed. There is nothing to categorise, nothing to correct, and no backlog if you miss a month.

The work is proportional to how many accounts you have — typically four to ten, and stable for years — rather than to how many purchases you make. It takes about two minutes and it is the same two minutes every time.

Miss a month and you have a gap in the chart. Come back and the next entry is just as accurate as if you had never stopped. Nothing needs reconstructing, because a balance is a snapshot rather than an accumulation. That is the property that makes it survivable.

Balances already contain the answer

Here is what is easy to miss: if you want to know whether you are saving, the balances tell you. If your total is €4,000 higher than three months ago, you saved €4,000. You do not need to have categorised anything.

Transaction tracking computes the same figure the long way — sum the income, sum the expenses, subtract — and it is more fragile at every step, because a single miscategorised transfer moves the answer.

What you lose is the breakdown. Balances say you are €4,000 up; they cannot say it was the restaurants. If diagnosing the composition is your goal, you need transactions and Walleet is the wrong tool.

But for most people the breakdown is not actionable. They already know roughly where the money goes. What they do not know is whether the total is moving in the right direction, and that is exactly what balances show.

One complication worth naming

There is a case where a balance change is not saving: currency movement. If you hold euros and read your net worth in dollars, your total moves when the rate does, without you doing anything.

Walleet splits the change into the part your balances contributed and the part exchange rates did, so a good saving month in a bad currency month does not read as failure. That is covered in more detail in what net worth in one currency actually means.

Investment gains sit in the same place. A rising portfolio is a rising balance, and Walleet does not separate it from money you added. If that distinction matters to you, a portfolio tracker is the better instrument.

The kinds of account this reaches

A quieter advantage: balance tracking works for assets nothing can aggregate.

Cash. A brokerage in a country no aggregator covers. A self-custodied wallet. A pension whose provider has no API. Money lent to a family member. A foreign account from when you lived somewhere else.

These are frequently the accounts that matter most to net worth, and they are precisely the ones transaction-based tools cannot see. A tool that only tracks what it can connect to shows you a confident, incomplete picture — and incomplete in a way that is invisible, because the missing accounts are simply absent rather than marked as missing.

If you can put a number on it, Walleet can track it.

Who this is wrong for

Being clear about it. Use something else if you want to know which categories you overspend, if you are running a household budget with envelopes and limits, if you need cashflow forecasting, or if you want expense records for a business or for tax.

Walleet is for the person who wants to know whether their net worth is going up, who has accounts in more than one currency or institution, and who will realistically sit down for two minutes a month rather than curating a transaction feed indefinitely.

That is a narrower product than most finance apps aim at. It is also one you can still be using in three years, which is the only timescale on which any of this becomes useful.
