A business credit card is a payment card issued in a company's name rather than an individual's, designed to help a business separate its spending from personal accounts, build a credit profile in its own right, and pull in rewards or working-capital perks tied to common business expenses such as advertising, shipping, office supplies and travel.
The differences that actually matter between one business card and another are not the headline sign-up bonus. They are how a card treats employee cards and spending controls, whether it offers category bonuses that line up with where the business really spends, and the structure of its ongoing interest rate, fees (annual, foreign-transaction and any per-employee charges) and intro financing. Those mechanics determine the card's real cost over a year of use.
On the comparisons below, weigh each card against the same short checklist: which expense categories earn the most back, what employee-authorisation and reporting tools are included, the full fee schedule, and the length and terms of any 0% intro period. Match those features to your typical monthly spend rather than to the size of the welcome offer.
