If this goes wrong: you choose a card that appears cheap but has conditional fees or restrictions that make it more expensive for your actual spending.

How to actually do it

Write down your business type, expected annual spending, currencies, number of cardholders, cash withdrawal needs and required controls or integrations.
Open the current official pricing, fee and eligibility pages for each business card you are considering, and save the page URLs.
Paste the relevant fee tables and terms into the prompt, keeping each provider name and source URL beside its information.
Paste the completed prompt into an AI chat and ask it to calculate the estimated cost for your stated spending pattern.
Compare every fee and assumption in the answer with the official pages you opened, correcting the table when a fee, condition or eligibility rule is missing.
Choose only from options whose eligibility and important conditional charges you have confirmed, then save the comparison and source pages with your expense records.

Prompt

Act as a UK business-expense comparison assistant. Find the lowest-cost business card for this use case using only the provider pricing, terms and requirements pasted below or linked from official provider pages. Do not invent missing prices, eligibility rules or features.

Business details:
- Business type: [sole trader, limited company or other]
- Expected card spending each month: [amount and currency]
- Expected annual card spending: [amount and currency, if known]
- Number of cardholders: [number]
- Expected cash withdrawals: [none or details]
- Expected foreign-currency spending: [amount or percentage]
- Need for employee cards, controls, accounting integrations or rewards: [requirements]
- Other requirements or exclusions: [requirements]

Provider information:
[Paste the current official pricing pages, fee tables, terms and eligibility information here. Include the source name and URL for each item.]

For each eligible option, produce a table showing the recurring fee, per-transaction fees, foreign-currency fees, cash-withdrawal fees, cardholder fees, setup or replacement fees, and any conditional charges. Calculate the estimated total cost for my stated use case, showing the assumptions and calculations. Separate confirmed costs from missing or conditional costs. Rank the options by estimated cost, then state which option is cheapest only within the supplied evidence. Flag anything I must confirm with the provider. Do not recommend a card if eligibility is not confirmed. Use pounds where the source provides pounds, and do not convert currencies unless I provide the exchange rate.

Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong

AI cannot see unpublished offers, negotiated pricing or provider decisions about your eligibility.
It cannot guarantee that its pricing information is current unless you provide current source material or a reliable live data connection.
It cannot decide what matters more when the cheapest card has weaker controls, support or accounting integration.
It can miss conditional charges hidden in product terms, so the final cost still needs checking against the provider.

Even on a YES, the friction has a name: real time truth, verification cost and judgement under ambiguity.

FAQ

Can AI find the cheapest business card for expenses?: Yes, if you give it your spending pattern and current provider pricing. It can calculate comparable costs and rank the options, but you must confirm the result against the providers' current fees, terms and eligibility rules.
What information does AI need to compare business cards?: Give it your business type, expected spending, currencies, number of cardholders, cash withdrawal needs and required features. It also needs current pricing and terms for the cards being compared.
Can AI check business card fees?: It can extract and organise fees from pricing pages and calculate an estimated cost for your use case. It cannot reliably fill in missing or conditional charges, so compare its table with the official provider terms.
Can I trust AI to choose a business card for my company?: Use it to make a documented shortlist, not as the final decision-maker. You remain responsible for checking eligibility, conditional fees, service limits and whether the card fits your expense controls.
