A commercial card program (including any organization-issued credit card, such as procurement, purchasing or ‘P-Cards’, travel cards, and others) is only as strong as two things: whether your cardholders actually know how to use their card responsibly, and whether you, as the program manager, are doing your part to make sure that knowledge sticks. Following commercial cardholder best practices isn’t a one-sided job. Miss either half, and you end up with the same result: an audit finding, a policy violation, or a conversation with a cardholder that nobody wanted to have.
So what does that look like in practice? Below are five areas where cardholder habits and program manager oversight need to work together. For each one, we’ll look at what you should expect from your cardholders, and what you need to be doing on your end to make sure it actually happens.
Documentation and Receipts: A Commercial Cardholder Best Practice
Let’s start with the basics. Cardholders should be submitting receipts and business justification promptly, not saving them up for one big batch at the end of the month. Waiting creates gaps, in memory and in paperwork, and gaps are exactly what make a perfectly legitimate purchase start to look questionable later on.
But this isn’t just on the cardholder. Set a clear submission deadline, and when documentation goes missing, follow up quickly instead of letting it pile up. A missing receipt caught in week one is a five-minute fix. A missing receipt caught in month three is a real problem, for the cardholder and for your audit trail. And the gap matters more than most people assume. According to ACFE’s Occupational Fraud 2024: A Report to the Nations, issues caught within six months carry a median loss of $30,000, compared to $250,000 for those that go undetected for two to three years. Timing isn’t a minor detail here, it’s of utmost importance.
Knowing What’s Allowed
Cardholders should know their spending limits and prohibited categories before they make a purchase, not after. Assuming something is probably fine is exactly how honest mistakes turn into policy violations, and most violations really are honest mistakes.
That kind of understanding doesn’t happen on its own though. It depends on you keeping policy language current and easy to find. A policy that hasn’t been reviewed in a few years, or one that’s buried in a document nobody ever opens, isn’t doing anyone any good. When something changes, get ahead of it and communicate it proactively. Don’t wait for a violation to be the thing that surfaces the gap.
Card Security and Reporting
Cardholders should keep their commercial card separate from their personal cards and report anything suspicious right away. You’d be surprised how many mix-ups happen simply because two cards look alike sitting in the same wallet. A labeled card or a dedicated slot goes a long way.
On your end, make reporting easy. If a cardholder has to dig around for a phone number or guess who to email when something looks off, chances are they won’t bother. A clear, well-communicated reporting path removes that hesitation, and it’s a lot easier to build before you need it than after.
Handling Ambiguous Purchases
Here’s one that trips up even well-intentioned cardholders, and it’s one of the harder commercial cardholder best practices to enforce: they should ask before they swipe when a purchase falls into a gray area, rather than making the purchase and just hoping it clears. Most policy violations aren’t willful. They’re judgment calls that went the wrong way, made in the moment by someone who genuinely wasn’t sure.
For “ask first” to actually work, though, there has to be someone to ask. Designate a real point of contact for these questions, someone cardholders can reach quickly, not a general inbox that gets checked once a week. Otherwise you’re asking for a habit that has no way to form.
Understanding the Audit Isn’t a Gotcha
Cardholders should understand that audits are routine and expected, not some punitive event aimed at them personally. Get that mindset right, and cardholders tend to be far more cooperative and a lot less defensive when questions come up.
That mindset starts with you. Reinforce it by communicating audit findings back to cardholders promptly, framed as feedback rather than a list of violations. Once cardholders see the audit as a normal part of how the program runs, instead of a mechanism built to catch them out, compliance tends to follow pretty naturally.
Building Commercial Cardholder Best Practices Into Your Program
None of this works as a one-time announcement you send out and forget about. Cardholder habits and program manager oversight have to reinforce each other continuously, through clear policy, responsive communication, and follow-through that doesn’t fade after the first quarter.
