How to track expenses by photographing receipts

The easiest way to track expenses is to photograph each receipt when you get it, use a small fixed set of categories, and spend five minutes a week checking the entries. Typing every line is what makes most people quit, so the method below keeps the capture to a few seconds and does the review in batches.

The short version

• Expense tracking usually fails because each entry takes too long, so make capturing one fast.
• Photograph the receipt at the till, or log it in one line straight afterwards.
• Use a short, fixed list of categories and resist adding more.
• Spend five minutes once a week checking that amounts and categories are right.
• Look at the monthly split by category, and spend your time on the categories you did not expect.

Why does expense tracking stop after a couple of weeks?

Most people start by recording everything in detail: the shop, the date, the amount, the category and a note. That is fine for the first few days. Then a busy week arrives, a stack of unrecorded receipts builds up, and catching up feels like a chore, so the log is abandoned.

The fix is to lower the cost of each entry rather than to try harder. Capture first and tidy later, and accept that the record will be slightly rough. A rough log you keep up beats a perfect one you stop after ten days.

How do I capture expenses without typing every line?

Capture at the moment you pay, because that is when the receipt is in your hand and the details are fresh. You have three realistic options:

1. Photograph the receipt. Two seconds at the till, and you can throw the paper away.
2. Log it in one line. Something like "Tesco 84.20" is enough. The shop, the amount and a category cover almost everything you will later want.
3. Speak it. Useful when your hands are full.

You do not need to record each item on a grocery receipt. One entry per receipt is plenty for seeing where the money goes.

Which expense categories should I use?

Pick a small, fixed set and stay with it. Too many categories means you spend time deciding, and the totals get diluted across labels that differ only slightly. Eight to ten broad ones cover most people: groceries, dining, travel, shopping, home, bills, health and entertainment, with an "other" for the rest.

Decide once what goes where. If coffee on the way to work counts as dining, it always counts as dining. Consistency matters more than the right label, because it is what makes month-to-month comparisons meaningful.

What should a weekly review look like?

Set a five minute slot, such as Sunday evening, and do three things:

• Check the amount on each recent entry against the receipt, especially any that were read from a photo.
• Fix any wrong categories.
• Add anything you forgot, such as a cash payment.

Keep it short on purpose. The goal is accurate data, not a detailed audit of your week.

What should I look at each month?

At the end of the month, look at the total and the split by category, then compare it to the month before. You are looking for categories that are bigger than you expected. Say what surprised you out loud, then decide whether to act on it. What your spending ought to be is your decision, so use the numbers to ask questions, not to score yourself.

How does this work in Planwell?

Planwell on the App Store has an Expenses tracker built for this method. It is one of 15 trackers you can switch on, and you only see the ones you choose.

Quick add at the bottom of the screen

The bar at the bottom of the Expenses screen reads "Log an expense or snap a receipt...". It takes typed text, voice or a photo, and you can attach up to three photos at once. Photograph a receipt and Planwell's assistant reads it and creates the expense. You can also type "Tesco 84.20" and let it work out the rest.

Check the amount it read

The assistant can be wrong, especially with crumpled or faded receipts. Always check the amount against the paper, and fix it if needed. This is the main job of your weekly review.

On privacy, Planwell's privacy policy says that when you attach a photo, the image is sent to the AI so it can read it, and that the photo is not stored on Planwell's servers. The policy is at planwell.me/privacy.

Month total, daily average and the split

The top of the Expenses screen shows how much you have spent this month in large type, with the number of expenses and about how much that is a day. A coloured bar beneath it splits the month by category, with the largest shares named, such as Travel, Groceries and Dining.

Planwell's categories are Groceries, Dining, Travel, Shopping, Home, Bills, Health, Entertainment, Education & Business, Gifts, Donations, Pets and Other.

Spending overview

Tap Spending overview ("Totals by month and category") to see a breakdown by type for a chosen month and a chart of the last six months. This is the screen for your monthly look.

Finding and filtering entries

Below the totals is a search box for expenses and a row of category pills, so you can tap Groceries and see only those. The filter button next to the search box lets you narrow by date range (this month, last month, this year or last year), minimum amount and currency. Entries are grouped by day, newest first.

Export

From the menu at the top of the screen you can export your expenses as CSV, Excel or PDF. The same menu lets you import a CSV and choose the currency your totals are shown in.

If you would like to log without typing at all, voice logging: how to track your day without typing covers it. Regular bills that renew on a schedule are better tracked separately, as described in how to track every subscription on your iPhone.

Planwell needs iOS 18 or later and costs US$3.99 a month or US$39.99 a year after a 7 day free trial. The local price is shown in the app. Download Planwell for iPhone and photograph your next receipt.
