Spending categories that show
where your money really goes.
WonderBon categorises spending not just by merchant or total, but line by line: groceries, toiletries, sweets, subscriptions, deposit refunds, tips and many more categories become visible.
The merchant is not the category.
Traditional budgeting apps file a REWE shop as "groceries" — full stop. But is that really true? A typical REWE receipt has 23 lines — and not all of them are food:
The merchant is not the category. The receipt tells the truth.
That's why WonderBon goes deeper: the app can read receipts at line level and show which categories really sit behind your shopping. A single receipt can contain groceries, toiletries, sweets, deposit refunds and household items all at once. When everything lands in one category, the overview is lost.
One receipt. Seven categories. Finally visible.
A real supermarket shop from a WonderBon beta phase — and what it actually looks like when every line is categorised individually:
Weekly shop with 7 different categories
| Bread | €2.95 | Groceries |
| Milk | €1.10 | Groceries |
| Crisps | €2.20 | Sweets |
| Cola | €1.55 | Drinks |
| Shampoo | €4.40 | Toiletries |
| Kitchen roll | €3.50 | Household |
| Cat food | €7.45 | Pet |
| Deposit | €0.60 | Deposit |
What happens when categories are missing.
Lots of households feel that somehow everything's getting more expensive — but can't say what exactly. Here are four typical consequences of missing categorisation:
"Where's my money?"
The balance drops, but each purchase felt fine. Without categories, this stays a gut feeling — and decisions get made on suspicion alone.
Hidden creep costs
Sweets, small subscriptions, deposit refunds, tips — individually harmless, surprising in total. Without categories they never surface in the monthly summary.
Vague inflation
"Everything's pricier" — everyone says it. But where exactly? Groceries? Energy? Restaurants? Without categories, there's no concrete lever to push against.
Unfair splitting
When everything's booked as "weekly shop", nothing can be split fairly. Whoever buys sweets should pay for them — but only if they're actually recognised.
"We thought it was the shopping — turns out it was the subscriptions."
A classic light-bulb moment from a beta family: they had a feeling the weekly shop had become more expensive. WonderBon showed: groceries had risen slightly, yes — but that wasn't the driver. It was eight small subscription charges that added up to over €490 across the year.
Without categories, this would never have surfaced. With categories, it became a clear decision: keep three subscriptions, cancel two, switch one. The result the next month: a noticeable budget effect, without anyone having to give up something they cared about.
"After 6 months we realised: we spend €190 a month on restaurants, not €70. That was a real eye-opener — and suddenly it wasn't abstract any more, it was something we could actually discuss." — from beta-phase user feedback
What looks small alone can be big over a month.
Some spending categories are so harmless on their own that they never land on the radar. In the monthly overview, they become visible:

None of these categories hurt at the till — but in total they easily exceed the monthly streaming stack. WonderBon makes this visible without judgement. It's not about banning anything. It's about spotting patterns.
Which categories WonderBon knows.
Eight standard categories that play a role in almost every household — plus as many custom ones as you like. Clicking a category opens the matching receipts in your dashboard:
Groceries
Bread, milk, fruit, vegetables, coffee, cheese, meat — the basics.
Toiletries
Shampoo, toothpaste, laundry detergent, cosmetics, personal care.
Drinks
Water, juice, soft drinks, beer, wine — everything that isn't a grocery staple.
Sweets & snacks
Chocolate, crisps, biscuits, ice cream — often underestimated.
Household
Cleaning supplies, kitchen roll, bin bags, batteries, small bits.
Children & family
Nappies, school supplies, kids' clothes, toys, nursery.
Pets
Food, litter, grooming products, vet expenses.
Subscriptions & fixed costs
Streaming, cloud, apps, memberships, insurance.
Plus more standards: deposit refunds, tips, restaurants, transport, health, leisure, other — and as many custom categories as you want to create yourself.
Three properties that make WonderBon categories strong.
Categories aren't statistics — they're a living system that grows with your household:
Automatic
"Recognised, not typed in."
WonderBon categorises during the scan — every line of the receipt, not just the total. No manual sorting, no dropdown clicks, no discipline required.
Customisable
"Your categories, your rules."
Standard categories fit, custom ones can be created. Families need school and pet, flatshares need deposit refunds and cleaning, couples need personal and shared — WonderBon adapts, not the other way round.
Connected
"Categories plus people plus receipts."
Categories don't sit in a vacuum. They're linked with people (who paid?), receipts (which one?) and splitting (private or shared?). Statistics become household logic.
Why WonderBon goes further than classic budget-app categories.
Six properties that decide in practice whether a category system is still being used after 4 weeks or not:
| Feature | WonderBon | Budget app | Banking app | Spreadsheet |
|---|---|---|---|---|
| Automatic categorisation | Yes, from receipt | Limited | Per merchant | No |
| Multiple categories per receipt | Yes | No | No | Manually |
| Line level instead of merchant | Yes | No | No | With effort |
| Linked to people | Yes | Per account | Per account | Manually |
| Realistic to maintain daily | Yes | Rarely | None needed | High effort |
Frequently asked questions
What are spending categories?
Spending categories help sort spending thematically — for example groceries, toiletries, subscriptions, household, sweets, deposit refunds or tips. In WonderBon, categories are derived automatically from the captured receipts, and every individual line can have its own category.
Why are spending categories important?
They show what your money is really spent on. Without categories you only see totals per merchant — with categories you spot patterns, cost increases and areas of daily life that otherwise stay invisible (e.g. sweets, small subscriptions or impulse toiletries).
Can WonderBon categorise spending automatically?
Yes. WonderBon recognises products and prices from receipts and assigns them to suitable categories — automatically during scanning. You can check, correct and adjust every assignment at any time. The app learns your specific preferences as it goes.
Can a single receipt contain multiple categories?
Yes, that's precisely the USP. Traditional budget apps file a supermarket shop as "groceries" — full stop. WonderBon splits the receipt at line level — so bread becomes groceries, shampoo becomes toiletries, cola becomes drinks and the deposit becomes deposit refunds, all from a single shop.
Can I create my own categories?
Yes. Categories can be fully adapted to your household. A family might need categories for children, school or pets. A flatshare creates categories for cleaning supplies, shared shops or deposit refunds. You can create, rename and re-categorise receipts whenever you want.
Can I link categories to people?
Yes. Categories and individual lines can be assigned to people, nicknames or household roles — so private and shared spending stay cleanly separated. Categories then feed directly into fair splitting and the monthly balance.
Can I see which category is getting more expensive?
Yes. WonderBon shows category development over time — monthly comparisons and trends. So you spot which areas of your spending are growing without it being just a gut feeling.
Not less living. Better understanding.
Categories aren't a tool for bans. They're a tool for visibility. What's visible can be discussed. What's discussed can be decided deliberately — not from doing without, but from clarity.
