7 Rules for a Corporate Card Policy That Keeps Your Books Clean Here is the math nobody runs before issuing cards to the team. Every uncategorized charge costs you twice. Once when your bookkeeper chases it, and again when someone has to fix the coding after the chase produces a shrug. And the chase happens three weeks after the purchase, which is roughly three weeks after anyone remembers what a $340 charge at a hotel in Denver was for. Ten cards at fifteen mystery charges a month is a part-time job you did not know you hired for. A corporate card policy is not a bureaucracy problem. It is the difference between books that close on the tenth and books that close whenever the last receipt turns up. Seven rules, in the order they matter. 1. A Corporate Card Policy Starts With What the Card Is For A card with no stated purpose becomes a general-purpose spending instrument, and the policy gets written after the damage instead of before it. Write one sentence per card, or per card type, that names what it is for. The sales team card is for travel and client meals. The ops card is for software subscriptions and shipping. The founder card is for everything else and gets reviewed monthly. This sounds trivial. It is the control that makes every rule after it enforceable, because "is this an appropriate charge" becomes a question with an answer instead of a judgment call about someone's character. 2. Set the Limits at the Card, Not in the Handbook A policy that says "use good judgment on purchases over $500" is not a limit. It is a hope. Modern card platforms let you set per-transaction caps, monthly caps, and merchant category restrictions at the card level. Use all three. A card that physically cannot spend $4,000 at once never generates the conversation about why it did. Merchant category controls are the second lock and the one most teams skip. A card restricted to software and advertising categories cannot buy a flight, which means nobody has to police whether the flight was reasonable. The tradeoff is friction. Set the limits too tight and you will spend your week approving exceptions, which trains everyone to route around the system. Set them where they catch the outlier, not the ordinary. 3. Require the Receipt at the Moment of Purchase Month-end receipt collection does not work. It has never worked. It will not start working because you send a firmer email. The rule that works is that the charge itself is the reminder. Card platforms push a notification within seconds of the swipe, and the receipt gets photographed then, while the person is still...
