THE STARTING POINT
Why expense tracking fails
It does not fail from lack of discipline: it fails because the system asked for more work than life allows. Any method that needs thirty minutes of weekly upkeep gets abandoned in three weeks.
The other common reason is not knowing what it is for. “Tracking my expenses” is not a goal: it is an activity. With no concrete question behind it, every number looks equally important and the effort stops paying off.
The five steps below are ordered so that the first one decides everything else. If you are only going to do one, do the first.
THE METHOD
Five steps, in this order
Each step is designed to cost little and to make the next one easier. No budgets and no spreadsheets full of formulas.
Decide what you want to know
Write down one concrete question: “how much do I spend eating out?”, “why do I run out of money when my pay hasn't changed?”, “what does the car actually cost?”. Just one. That question decides what you need to log and, more importantly, what you do not.
Separate your money into few places
You do not need to replicate your bank. Two or three accounts are usually enough: day-to-day, cash, and shared money if it exists. Fewer places means fewer decisions every time you spend, and decisions are what wear you out.
Log in the moment, or leave a trace
Logging takes fifteen seconds if you do it when you pay and fifteen minutes if you leave it for Sunday. When you cannot log, leave a trace: keep the receipt or take a photo of it. An imperfect trace is worth far more than memory.
Review once a week, five minutes
Look at only two things: anything you do not recognize, and which category took more than you expected. A short weekly review catches what a long monthly review can no longer fix.
Change one single thing
After three or four weeks you will have an answer to your question. Change one thing and leave it for a month. Three changes at once cannot be measured, and what cannot be measured gets abandoned.
WHAT TO AVOID
Five mistakes that make people quit
- Starting with thirty categories. Five to eight is enough; split one when it grows too big to answer anything.
- Trying to rebuild the last six months before starting. The past will not change; start today and in a month you will have your own data.
- Chasing the last cent. A two-euro gap changes no decision. The precision you need is the kind that tells €40 from €400.
- Logging only at month end. That is exactly when you remember nothing and when the work has piled up enough to feel like a chore.
- Quitting after a bad month. A month with a repair or a trip does not invalidate the method: being able to look at it separately is the whole point.
WHAT TO USE
Which tool fits this method
Any of these works. What changes is how much effort each one asks for and how much of your money it gets to see.
Tally belongs to that last category, and the rest of this guide explains how the five steps map onto it. The method does not depend on that: if you already have a tool you actually keep up with, stay with it.
| Tool | Good for | What it costs |
|---|---|---|
| Paper or notes | Starting today, with nothing to install, and for step 1. | It does not add up or group: the weekly review is manual and there is no useful history. |
| Spreadsheet | People who already know one and want total control over the columns. | You maintain formulas and usually open it on a computer, so step 3 gets postponed. |
| Bank app | Seeing that bank's movements with no effort. | It only sees that bank: no cash, no other cards, no receipts, and it categorizes on its own. |
| App with bank connection | People who want movements from several banks to appear on their own. | You have to give the app or an aggregator access to your accounts, and cash is still left out. |
| Manual app with import | Logging in the moment, keeping receipts, and pulling in a statement when it helps. | You decide when each movement gets in: nothing appears by itself. |
WITH TALLY
How each step maps onto Tally
Tally is built for short sessions: log, review, move on. It does not ask you to set up a budget before you start.
| Step | In Tally | Free or PRO |
|---|---|---|
| 1 · What you want to know | The 17 built-in categories answer almost any first question with nothing to configure. | Free · custom categories with PRO |
| 2 · Separate | Create the accounts you need. A trip or a move can live in an event account, outside your totals. | 3 accounts free · event and unlimited accounts with PRO |
| 3 · Log | Tap +, amount, account, category. Or attach the receipt photo, which stays on your phone; tap “Analyze receipt” and Tally proposes amount and date for you to review. | Free · 1 AI analysis, unlimited with PRO |
| 4 · Review | History with search for anything you do not recognize, and statistics by month, quarter, semester, or year for the category breakdown. | Free · custom date range, monthly comparison, trend, and category evolution with PRO |
| 5 · Change one thing | Save what repeats as a recurring item and use a goal to set money aside with a clear intention. | 1 recurring item and 1 goal free · unlimited with PRO |
WITHOUT BANK SYNC
Do you need a bank connection for this?
No. Step 3 can be solved in four different ways, and none of them needs access to your bank account. What it does need is for you to confirm what gets in.
With Tally PRO you can import a statement you download yourself (CSV, Excel, or Spanish Norma 43), review the rows, and confirm them. It is useful for pulling in a card's whole month at once, but it is not the same as connecting a bank: you choose the file and you approve it.
The trade-off is honest: nothing appears on its own. In exchange you also see the cash, the receipts, and the accounts no bank knows about, and there are no banking credentials anywhere.
TO BE CLEAR
What Tally does not do
This method does not need budgets, and it is worth saying that Tally does not have them either. If your problem is planning before you spend, there are better tools.
- No category budgets and no envelope-style money assignment: YNAB or Actual Budget fit that better.
- It does not connect to banks or download movements on its own.
- It does not use real-time or historical exchange rates, and does not convert when saving: each movement keeps its currency.
- It does not split expenses between people or calculate debts.
- It requires an account: there is no guest mode.
VARIANTS
The same method in two concrete cases
Expenses as a couple
The steps do not change; step 2 does. One shared account for what is common and each person's own accounts kept apart.
Travel expenses
Step 2 taken to the extreme: the trip in its own account, so it does not wreck the month. And step 3 leans on receipts.
FAQ
Frequently asked questions
How much time does this actually take?
Under a minute a day if you log when you pay, plus a five-minute review once a week. If a method asks for more than that on an ongoing basis, it is too big to keep up.
Do I need to make a budget?
Not to start. A budget is an answer, and this method is for getting the question and the data first. If you later want category budgets, you will need a tool that does them: Tally does not have budgets.
How many categories should I use?
Five to eight at first. You add one when a category grows so big it stops answering anything — not before.
Do I have to log absolutely everything?
No. Log what answers your question and group the rest into one general category. A method that demands logging a €1.20 coffee gets abandoned before it becomes useful.
Does it work if my income is irregular?
Yes, and all the more so: with irregular income what matters is knowing your spending well, because that is the part you can measure precisely.
Do I need to connect my bank?
No. You can log by hand, photograph receipts, or import a statement you download yourself. In Tally, statement import is PRO and always goes through your review before saving.
What if I have not logged anything for months?
Start today. Rebuilding the past costs a lot and changes no future decision. In four weeks you will have your own data, and enough of it.
