As a finance manager, you'll inevitably face the question: "Should we use corporate cards or stick with expense reimbursements?"
The honest answer? It depends. And the decision isn't really about preference—it's about structure, control, and how well the system scales with your business.
Both corporate cards and expense reimbursements have their place. But without the right approach, either model can create friction: employees waiting weeks for reimbursements, finance teams drowning in receipts, or uncontrolled card spend slipping through the cracks.
The real challenge isn't choosing one over the other. It's understanding when each makes sense, and building a system that works for your people and your business.
Corporate cards vs. expense reimbursements: what's the difference?
Before diving into trade-offs, let's clarify what we're comparing.
Corporate cards are company-issued cards that employees use for approved business expenses. The company pays directly, transactions happen before any formal review, and real-time tracking is possible—provided you have the right systems in place.
Expense reimbursements work differently. Employees pay out of pocket for work-related expenses, submit a claim, and get reimbursed after the claim’s been approved. Finance reviews everything before any money leaves the company.
Here's how they stack up at a glance:
| | Corporate card | Expense reimbursement |
| Who pays upfront? | Company | Employee |
| Visibility | Real-time | Delayed |
| Admin focus | Reconciliation | Claims processing |
| Control point | Pre-spend (if limits set) | Post-spend |
| Primary risk | Misuse without controls | Delayed oversight |
Both models solve the same problem—managing business spend—but they do it in fundamentally different ways.
Corporate cards: when they work, and when they don't
When they work
Corporate cards solve one of the most frustrating problems in business travel and spend: employees fronting large amounts of their own money.
When someone books a £1,000 flight or pays for a week-long hotel stay, asking them to wait a month for reimbursement isn't just inconvenient—it's unfair. For junior staff or employees without significant savings, it can create real financial stress.
From a finance perspective, corporate cards offer something equally valuable: real-time visibility.
When spend happens through company cards, you can see it the moment it occurs. There’s no waiting weeks for claims to trickle in, and no surprise claims at month-end.
When cards are set up properly, the control is baked in from the start:
Spend limits per employee or per transaction
Blocked vendors and categories
Policies enforced at the point of purchase
Instant notifications for every transaction
The ability to freeze or terminate cards immediately
All of this means you're managing spend proactively, not reactively.
Corporate cards also eliminate the entire reimbursement cycle. There are no claims to review, no manual data entry, and no back-and-forth chasing missing receipts. Expenses are generated automatically, receipts are matched to transactions, and reporting becomes straightforward.
For frequent spenders like sales teams, consultants, or execs corporate cards simply make sense. The volume justifies the infrastructure, and the time saved adds up quickly.
When they don't
Corporate cards without proper controls can quickly become a liability.
Without transaction limits, category restrictions, or real-time monitoring, employees can easily overspend—and you won't find out until the money’s been spent. Misuse doesn't have to be malicious, it can just as easily be accidental. For example, someone books a flexible flight because they're not sure of their plans. Or another employee adds a dinner to the company card without realizing it's outside policy. These small slips can compound.
Then there are the costs that creep in with some corporate card providers: annual card fees, foreign exchange charges, and the admin overhead of managing unused cards that are still generating statements.
This is where finance teams get stuck. Cards seem like the easy solution until you choose a card provider without the right controls and safeguards in place that ensure you and your teams get the full benefit.
Expense reimbursements: when they work, and when they don't
When they work
Reimbursements offer something that appeals to every finance team — control before commitment.
With reimbursements, no money leaves the business until the expense has been reviewed, categorized, and approved. It's a finance-first model that keeps spending decisions firmly in your hands.
There's also a behavioral component. When employees are using their own money, they think twice. There are fewer impulse purchases, less casual overspending, and more scrutiny before the card comes out.
For companies with simple needs like small teams, infrequent travel, and low transaction volumes, reimbursements are straightforward to implement. There’s no card infrastructure required, just a clear policy and an approval process.
And for employees who travel rarely, for example an operations manager who attends one conference a year, it doesn't make sense to issue them a card. A reimbursement works perfectly fine.
When they don't
But reimbursements have their own friction points, and they show up fast as a company scales.
The biggest issue is the employee burden. You're asking staff to float company costs, which creates stress, especially for junior employees or anyone without significant cash reserves.
Then there's the admin. Finance teams end up chasing receipts, reviewing spreadsheets, and approving line items one by one. Multiply that by 200 employees, and it's not just tedious, it's unsustainable.
The other, often overlooked, challenge with reimbursements is they don't give you real-time visibility. You don't know what's been spent until it's claimed, which could be weeks after the fact. That makes financial forecasting harder, budgeting less accurate, and month-end close a scramble.
As for policy compliance? Without built-in rules or automated checks, employees are relying on memory or best guesses. You're left untangling mistakes after the money's already gone.
Reimbursements might feel controlled, but it often comes at the expense of speed, visibility, and scale.
5 questions to ask to decide which is right for you
Choosing between corporate cards, reimbursements, or a combination of both is about finding the right fit for your company, your employees, and your finance team.
Here's how to pressure-test your current setup:
1. How frequently are employees spending?
Frequent spenders benefit from the speed and automation of corporate cards. The volume justifies the infrastructure, and the time saved compounds quickly.
Infrequent or ad hoc spenders are often better served by reimbursements.
2. Do you have a strong expense policy and a team you trust to follow it?
If you have clear spending policies and can enforce them with card-level controls (transaction limits, blocked categories, real-time notifications) using a platform like Perk, corporate cards reduce admin and keep teams moving.
If you're unable to manage controls at the card level and enforce policy before any money is spent, then reimbursements with post-spend approvals offer tighter oversight.
3. How stretched is your finance team?
Automated card workflows reduce manual checks and reconciliation time. Expenses are generated automatically, receipts are matched in real time, and month-end close is cleaner.
4. How important is real-time visibility?
If forecasting accuracy matters, if you're scaling fast, and if surprises at month-end aren't acceptable then cards give you a live view and proactive control.
Reimbursements show up later, so you’re always catching up.
5. Are compliance and audit-readiness non-negotiable?
Both methods require documentation. The difference is when and how that documentation flows.
With cards, you need a system like Perk that captures receipts automatically and matches them to transactions in real time. With reimbursements, you're relying on employees to submit everything correctly.
Either way, an expense platform that automates receipt capture and record-keeping keeps your team compliant without the paper trail panic.
Why more finance teams are choosing a hybrid approach
For many businesses, the answer isn't corporate cards or reimbursements — it's both.
Cards for regular, high-value, high-frequency spenders like sales, consultants, and execs
Reimbursements for mileage, occasional travel, and low-frequency staff
This hybrid approach avoids the extremes. You're not issuing cards to everyone and risking unnecessary spend, but you're also not forcing frequent travelers to front thousands in personal cash.
However, this only works smoothly when both corporate cards and reimbursements flow through the same system.
When cards and reimbursements are managed separately, you double your workload and it leads to fragmented data, duplicated effort, and reconciliation nightmares.
But when both feed into a single platform? Automated reconciliation. Unified reporting. Real-time visibility across all spend. Policy enforcement across both flows.
The decision between cards and reimbursements starts to matter less when the system handling both is designed to remove the friction.
Does the expense platform matter?
Yes. Enormously.
Whether you’re using corporate cards, reimbursements, or a combination of the two, it only works if the platform supporting it removes friction from the process.
That means:
Automated expense creation for every card transaction
AI-powered receipt matching so employees aren't manually entering data
Real-time policy enforcement across both cards and claims
Unified reporting so finance sees all spend in one place
Audit-ready data from day one, with no manual reconciliation required
When your travel, expenses, and card payments run through one platform, the work behind the work disappears. Employees book trips, expenses are filed automatically, and finance has full visibility without chasing anyone down.
Perk supports both corporate cards and reimbursements on a single platform—so you don't have to force one approach on every situation. Match the model to the employee, the role, and the spend frequency. Then let the platform handle the rest.
