Corporate Card Security Best Practices for Canadian Businesses

Corporate cards should make business spending smoother, not riskier. But without the right controls, visibility or policies, even well-meaning teams can open the door to fraud, misuse and costly mistakes.

Nobody likes the thought of fraud happening in their organization, but ignoring it is not an option. The longer a dishonest employee works for the company, the greater the impact. Median costs lost to a bad actor rocket up to a quarter of a million dollars over a decade or more, according to the Association of Certified Fraud Examiners.

Seb Prost, CPA and founder of LedgerLogic, has helped guide business owners through these concerns. His firm provides tax, accounting and virtual CFO services for Canadian businesses looking to modernize their finance stack and reduce the friction of traditional banking tools.

In this article, Seb walks through the risks he sees most often and the corporate card security best practices that help companies take a proactive stance in credit card fraud prevention.

The importance of managing corporate card security

Corporate card fraud rarely looks like a high-stakes heist. More often, it’s unintentional misuse or a small purchase here and there. Even so, the cost adds up. And it’s even harder to spot red flags when your team shares cards or lacks oversight.

“The lack of real-time visibility into spending is a huge issue, especially with legacy banking,” says Seb. “You might not know until month end what was actually spent.”

Delayed reconciliations, shared cards and hard-to-cancel access are all vulnerabilities that Seb’s clients face. These issues pose a risk, especially when no one’s sure who made a charge or whether the expense aligns with someone’s role. With help, these businesses can implement better financial management controls that are key to preventing corporate card misuse.

Biggest safety risks

When it comes to corporate card security, the most common risks aren’t always the most obvious. Sometimes the issues are real security risks, while others are simply due to a lack of clarity. 

Here are a few of the most common risks Seb advises businesses to watch out for:  

Lack of visibility

Without real-time spend tracking and timely receipt submission, unauthorized charges can fly under the radar for weeks or even months. 

Shared cards

As soon as a card changes hands, there’s an opportunity for murky details or misuse. “If it’s just one card for multiple people, how do you even know who spent what?” asks Seb.

Orphaned cards

Former employees with lingering access can create serious exposure if cards aren’t cancelled immediately.

Receipt gaps and role mismatches

Expenses that don’t align with a person’s responsibilities or arrive without documentation should cause concern. 

5 tips to better your corporate card security management

The risks are real, but can be managed. With the right policies and financial management tools in place, you’ll be well on your way to preventing corporate card misuse while empowering your team. 

1. Develop a comprehensive corporate credit card policy

Think of your credit card policy like a seatbelt. It should click into place before anyone starts driving. It’s your first line of defence to preventing any security issues. Define who gets a card, how it should be used and what happens when someone breaks the rules.

Seb recommends setting clear eligibility criteria, pre-approval thresholds and usage guidelines tied to specific roles and responsibilities. 

“Does it make sense that this person gets a card?” he says. “If someone’s in IT, maybe they need to pay for a subscription. A salesperson might need travel funds. But not everyone needs a card that can be used for anything.” 

The policy should also list prohibited uses (like personal expenses) and the consequences for credit card misuse. And don’t let your corporate credit card policy collect dust. “Review it periodically, especially if there are changes in how the business operates,” says Seb.

2. Implement financial management controls

Internal controls are essential for spotting fraud early. For example, you can assign individual cards instead of shared ones for more clarity. “You want to be able to track an expense back to an individual, not a team,” Seb says.

Real-time transaction feeds help business owners or accountants flag issues quickly. “You can pop into Float and review expenses daily if you like,” says Seb.

Other smart controls include:

• Regular reviews by accountants or management
• Setting and reviewing transaction limits
• Segregation of duties so the same person isn’t both spending and approving 

3. Use technology to enhance security

Legacy systems walk. Modern solutions run, with real-time visibility, instant card controls and tech that doesn’t make you beg a banker for a call back. 

“Instant card issuance and freezing is a big one,” says Seb. “If somebody joins or leaves, you can issue or cancel a card right away with no need to call the bank.”

He also recommends category-level restrictions. “If you can limit based on what the person actually needs, that’s super helpful,” he says. 

Other features that stand out include:

• Adjustable spending limits that reflect project budgets or one-off needs
• Cloud accounting integrations that eliminate manual data entry
• Automatic receipt capture and reminders to cut down on paperwork and errors

“Automation helps catch issues early and significantly reduces the administrative burden on finance teams,” says Seb. 

4. Set appropriate corporate card limits

Card limits aren’t one-size-fits-all. “Base limits on the employee’s role and the type of expenses they might incur,” Seb says. A salesperson might need more flexibility, while admin staff might only need a small recurring amount.

He also suggests adjusting corporate card limits monthly when needed, like busy seasons or to attend a trade show. He also recommends enabling real-time alerts so employees know when they’re approaching their cap. 

5. Educate employees on security best practices

Policies only work if people follow them. “It starts with clear communication and training,” says Seb. 

He recommends a quick onboarding session when issuing cards, including examples of acceptable and off-limits purchases. “Equally important is reinforcing that card access is a responsibility, not a perk.”

Seb also flags receipt collection as a chronic pain point. “Especially for outsourced bookkeepers, it’s hard to get clients to provide supporting documentation,” he says. That’s where Float’s automated reminders can offer help.

“When employees get a text reminder to upload their receipt right away, it makes a big difference,” says Seb. “It reinforces good habits.” Finance teams can also offer transparent feedback to help employees stay compliant without friction.
