Not just that you bought — but what.
A banking app shows you €83.47 at REWE. Bon.line shows you the twelve products behind it — including cash purchases, online orders and automatic categorisation.
Same shop, same amount — but two completely different worlds of insight. Only at the product level does it become visible what your money was really there for.
What your banking app doesn't see.
Banking apps are great for balances, standing orders and liquidity. For real shopping analysis they have four structural gaps.
No categories at product level
Banking apps categorise per retailer. A REWE shop becomes "Groceries" — even if half was chocolate, beer or toiletries.
Cash is invisible
Whoever pays cash at the bakery, market or kiosk appears in the banking app only as "ATM withdrawal". What the cash was spent on? Completely unclear.
Online purchases as a black box
€87.30 at a large online retailer — book or vacuum cleaner? Grocery delivery or gift? The bank transaction doesn't say.
No splitting possible
Banking apps are single-person apps. Who in the household paid for what — and whether it was joint or private — stays unanswered.
When the receipt suddenly tells you more than the account.
There's that moment when you see for the first time what's actually behind "€247 at REWE this month". How much of it was fresh produce. How much drinks. How much chocolate. And how much was things you didn't actually want to buy.
Banking apps give you a balance sheet. Bon.line gives you a picture.
"My account says: €247 REWE this month. My receipt says: €38 of that was sweets — I didn't want that." — from the Bon.line manifesto
From receipt to product level in three steps.
No manual typing, no category clicking. Bon.line handles the tedious part.
Photograph the receipt
Take a photo right in the app, upload PDFs for online orders or forward by email from your inbox. Works with cash receipts too.
AI recognises products
Trained on real German receipts: retailer, date, individual items, prices, discounts and deposit. Works with crumpled receipts and thermal-paper print too.
Categorise & split
Automatic categories for every product line. If needed, assign individual items to people in the household — ready for the monthly analysis.

Isn't my banking app enough to analyse my spending?
A banking app shows you how much you spent in total at REWE, dm or Aldi — but not what you bought there. For a real shopping analysis you need the product level: individual items, quantities, prices, categories. A receipt has all that. Bon.line reads it for you.
What about online orders that appear as a lump sum in the banking app?
Online orders are the biggest gap in any account-based analysis. €87.30 at a large online retailer could be a book or a vacuum cleaner. Bon.line accepts order confirmations from your email inbox or as a PDF upload and recognises the individual products from them just as it does from a receipt.
How long does it take to capture a receipt with Bon.line?
Take a photo, quick check, save — typically under 30 seconds per receipt. The AI recognises retailer, date, individual product lines, prices and assigns categories automatically. You only need to confirm or make corrections if the AI gets something wrong.
What happens to the photo of the receipt? Is it stored?
The receipt photo is processed for AI recognition and then stored in your digital receipt archive — securely stored on German servers, visible only to you and your household. AI processing is done without using your data for training purposes. You can export or delete any receipt at any time.
Does it work with cash purchases that don't appear on the bank statement?
This is exactly where the main advantage over banking apps lies: Bon.line isn't interested in the bank transaction but in the receipt. Whether you paid in cash, by card, with a loyalty app or with a voucher doesn't matter. As long as you have a receipt, the expense appears in your analysis — including cash purchases that would be completely missing from the banking app.
How does Bon.line automatically assign categories to products?
Bon.line recognises product names and compares them with a category database trained on real shopping data — groceries, toiletries, sweets, drinks, tobacco, pet supplies, stationery, household and more. You can correct categories any time, and Bon.line remembers your adjustments for the future.
