Choosing a receipt scanner app: what actually matters
The best receipt scanner app saves clean PDFs, extracts data without guessing, lets you search, exports PDF and CSV, respects privacy and has a clear price.
In short: A good receipt scanner app saves every receipt as a clean PDF, extracts the amount, date and merchant without guessing, lets you search and categorise, exports everything in open formats such as PDF and CSV, and treats your data so that you know where it lives. Price and platform come after that. The best receipt scanner app is the one you are still using six months from now.
The App Store and Google Play list dozens of apps that scan receipts. They all look similar in the screenshots, and the ratings help little, because most users rate after the first week, not after the first tax year. The differences only show once you have 300 receipts in the app and your accountant wants a list.
This article names the criteria that really count in everyday use, in order of importance. It helps you check an app in ten minutes instead of switching after three months and re-entering everything.
What must a receipt scanner app do at a minimum?
It must turn a photo into a complete, legible receipt saved as a PDF. That is the basic function, and a surprising number of apps only half deliver it.
Specifically, that means:
- Automatic cropping and straightening. You take the photo, the app finds the edges and squares the receipt up. Without this, you crop every scan by hand.
- Contrast, not filters. The app makes the text darker and the background lighter without smearing the digits.
- PDF as the storage format. Not JPGs in a gallery. PDF is the standard for accountants and bookkeeping software; the reasons are in Converting receipts to PDF.
- One receipt per file, multi-page where needed. A two-page invoice belongs in one PDF; two till receipts belong in two.
Test this in a shop with a real receipt, not with the smooth invoice on your desk. A crumpled receipt on a wooden tabletop shows immediately whether the detection is any good.
How well does the app read the amount, date and merchant?
It should recognise the fields but only fill in what it has read with confidence. This criterion separates useful apps from dangerous ones.
Automatic extraction saves the most time: instead of typing the amount, date and merchant, you only check what the app found. The problem is the error rate. Receipts are badly printed, faded and crumpled, and text recognition confuses 8 and 3, 1 and 7, CHF and EUR. An app that simply fills in something when it is unsure produces errors you only notice at year end, when the totals do not add up.
Pay attention to how the app handles uncertainty. Belego leaves a field blank if it is not clearly readable, and you complete it by hand in that moment. That is less spectacular than an app that always fills everything in, but it is more reliable. Why guessing is so risky with receipts is explained in AI receipt recognition: what it can do, what it cannot.
Also check whether you can override every extracted field by hand. An app that forces its recognition on you is unusable in practice.
Can you find a receipt again after a year?
A receipt app must offer search, categories and an overview by period. Otherwise you have a gallery, not a filing system.
The test is simple: imagine your accountant asks for the receipt for the office chair from last spring. Can you find it in ten seconds? For that, the app needs:
- Full-text search across merchant, amount and notes
- Categories you can adapt yourself
- A yearly or monthly overview to spot gaps
- Filtering by date range
- Support for several currencies if you shop abroad
Which categories make sense depends on what you need the receipts for. A handful is usually enough; more on that in Receipt categories that make sense.
Can you get your receipts back out of the app?
Export is the most important criterion that almost nobody checks before buying. An app without a complete export in open formats is a trap, however nicely it scans.
Three situations where you need the export: your accountant wants a year's worth of receipts. You change phone or app. The app is discontinued. In all three cases you must be able to reach your data without loss.
| Criterion | Good | Problematic |
|---|---|---|
| Receipt format | PDF, individual, descriptively named | Only visible in the app, JPG collection |
| Data list | CSV with date, merchant, amount, category | Only a PDF report, no CSV |
| Selectable period | Year, month, from-to | Full export only, or per receipt |
| Export in free version | Yes | Subscription only |
Belego exports any period you choose as a ZIP: the original PDFs named by date, merchant and amount, a CSV list with category and note, and a README so that someone without the app understands the structure. The PDFs suit bexio and similar tools, the CSV suits Banana, CashCtrl or Excel. What a usable CSV must contain is covered in Exporting receipts as CSV.
Where do your receipts live, and who can see them?
Receipts reveal more about you than you might think: where you shop, what you earn, which medicines you collect, where you spent the weekend. So check where the app stores its data before your first scan.
The two models:
- Cloud apps upload every receipt to the provider's server. Advantage: automatic sync across several devices. Disadvantage: you need an account, the data sits with a third party, and if the provider shuts down or is breached, your data is affected.
- Local apps store everything on the device. Advantage: no account, no login, no data with the provider, works offline. Disadvantage: you are responsible for backups yourself, usually via export.
Belego belongs to the second group: all receipts stay on the phone, there is no account and no tracking, and only automatic extraction needs a brief internet connection. The trade-off between the two models is discussed in A receipt app without the cloud. In any case, read the privacy policy in the store before you enter 300 receipts.
How much should a receipt app cost?
As much as the time it saves you, with a pricing model you understand. Both are unclear with many apps.
Typical models: one-off purchase, monthly subscription, annual subscription, or a free version with a limit and a Pro subscription. Watch three things: what exactly the free version includes, whether there is a scan limit, and whether export works without a subscription. An app that locks you out of your own receipts without a subscription has you over a barrel.
For comparison, Belego's model: the free version allows unlimited scanning and managing, export and backup are included, and automatic extraction is limited to 10 receipts per month. Pro costs CHF 10 per month or CHF 50 per year and extracts without limit. If you have few receipts, you do not need a subscription; if you have many, the subscription saves you the typing.
Do the sums soberly: if you have 30 receipts a month and save two minutes of typing per receipt, that is an hour a month. Whether an app is worth it at all compared with a spreadsheet or a folder is the topic of Receipt app, spreadsheet or folder: which one fits you?.
What a receipt app does not need to be
An accounting program. That is the most common confusion when choosing. A receipt app collects, extracts, organises and exports. The bookkeeping itself, meaning accounts, VAT returns and the balance sheet, is done by your Treuhänder (the Swiss term for a trustee or accountant) or by an accounting tool that imports the receipts.
Apps that try to do both are usually mediocre at both and tie you to their ecosystem. Better an app that captures receipts cleanly and passes them on in standard formats, so you remain free in your choice of accounting software and accountant. How scanning itself works day to day is shown in How to scan receipts with your phone.
Frequently asked questions
Do I need different apps for iPhone and Android?
Only if you use both devices at the same time. Most receipt apps exist for both platforms, but check whether the feature set is identical, since some providers develop for iOS first. When switching between platforms, the export is what counts: with a ZIP of PDFs and a CSV you can keep using your receipts on any device, even without the original app.
What is the difference between a scanner app and a receipt app?
A scanner app, such as the scan function in a notes app, turns photos into PDFs and nothing more. A receipt app does that too, but additionally extracts the amount, date and merchant, offers categories, search and overviews, and exports a list for bookkeeping. With a few receipts a year, the scanner app is enough; from about one receipt a week, the receipt app pays off.
Does a receipt app work without internet?
With locally stored apps, yes: scanning, searching and exporting work offline. Only the automatic extraction of amount and date needs a connection in most apps, because the recognition runs on a server. Cloud apps need internet for almost everything, because the receipts are stored there. For travel and building sites without reception, that is a decisive difference.
Can I manage emailed invoices with a receipt app too?
Many apps let you import a PDF straight from your mail app via the share function, so that digital invoices sit next to your scanned till receipts. That is convenient because you then have one place for all receipts. Before choosing, check whether PDF import is supported and whether the app also extracts the amount and date from imported files.
