Bagged and Open Banking budgeting apps
They see the total at the supermarket. Bagged sees the basket.
UK budgeting apps are built on Open Banking, which gives them a permissioned feed of your transactions. Each one carries a merchant, an amount, a date and a reference. They categorise those transactions and show you where your money went by category.
For the example receipt, the entire event as a budgeting app sees it is one line: £36.19 at a supermarket. Bagged sees 16 products, £32.29 of which was food and drink.
The short answer
Complementary. A budgeting app is the right tool for total household spending and Bagged does not replace it. Bagged goes one level deeper into a single category, using a record the banking system never sees.
Side by side
| Feature | Open Banking budgeting apps | Bagged |
|---|---|---|
| Data source | Open Banking transaction feed. | A photograph of the receipt. |
| Finest detail available | Merchant, amount, date. | Product name, quantity and price actually charged, per line. |
| Scope | All spending, every category. | Groceries only, in depth. |
| Food and non-food | Counted together. On the example, £3.90 of non-food would sit inside a grocery total. | Separated. Non-food is reported on its own and excluded from the headline. |
| Price rises | Not separable from buying more. | Separable, because the same named product can be compared week to week. |
| What you ate | Nothing. | The processing classification of everything bought. |
| Access required | A connection to your bank accounts. | No banking access of any kind. |
What Open Banking budgeting apps does well
- They cover all of your spending, not one category, including rent, transport, bills and subscriptions.
- The feed is automatic once connected, with nothing to photograph or scan.
- They can act on the whole financial picture: balances, upcoming payments, subscriptions you forgot about.
- Categorising and budgeting across every merchant is genuinely useful, and Bagged does not attempt it.
What it does not cover
- A transaction contains no line items, because the basket is not part of a card payment.
- A grocery total includes anything else bought in that shop, so it is not a food figure.
- A larger bill and a more expensive bill are indistinguishable from a total.
- They can say nothing about what was in the trolley.
This is a limit of the rails, not of the apps
It would be unfair to treat the missing line items as a shortcoming of any particular budgeting app. Card payments simply do not carry basket data. No amount of product work inside an Open Banking app produces a list of what you bought, because the information never left the till.
The itemised record does exist, on the paper handed to you at the checkout, and it is normally binned within a day. This is discussed further in why your banking app cannot see your food.
The question each one answers
A budgeting app answers how much am I spending, across everything. Bagged answers what am I actually buying, in one category. Most households have a use for both, and Bagged asks for no access to any account to do its part.
Common questions
- Can a budgeting app show my supermarket items?
- No. Open Banking exposes transactions, which carry the merchant, amount and date. Line items are not part of a card payment, so no app built on that feed can show them.
- Does Bagged need access to my bank account?
- No. Bagged never asks for banking credentials or an Open Banking connection. It reads a photograph of a receipt.
- Can Bagged replace my budgeting app?
- No. Bagged covers groceries only. A budgeting app covering every category of spending does a job Bagged does not attempt.
- Can Bagged tell me if my food shop got more expensive?
- It can distinguish a more expensive basket from a bigger one, because it compares the same named products across shops. That needs at least two receipts containing some of the same items.
