Most comparisons of corporate cards and expense reimbursements ask which model wins. That's the wrong question because there's a split. According to the Federal Reserve's 2026 Report on Employer Firms, 34% of firms that regularly use a credit card use both a business card and a personal card, while only 58% use a business card alone. The real question becomes which spend belongs on a card, which belongs in a claim, and what it costs your close to run both badly.
A corporate card puts company credit at the point of purchase, so company funds leave first and finance reviews the charge afterward. An expense reimbursement puts the employee's own money at the point of purchase, so finance reviews the claim first and company funds leave afterward. That reversal decides who carries the float, when policy is enforced, and what your controller reconciles at month-end.
| Factor | Corporate card | Expense reimbursement |
|---|---|---|
| Who funds the purchase | The company, at the moment of purchase | The employee, from personal funds |
| When policy is enforced | Before or during the purchase, if limits are configured | After the fact, at claim review |
| Who carries the float | The company | The employee, until the claim clears |
| What breaks first at scale | Unmatched transactions and missing receipts | Claim volume and approval turnaround |
Cards are the better model when spend is large, frequent, or booked under time pressure, because those are the conditions where asking an employee to front the money creates a real problem. Reimbursements are better when spend is infrequent, unpredictable, or concentrated in employees who would otherwise carry a card they use twice a year.
| Spend category | Better fit | Reason |
|---|---|---|
| Air travel and lodging | Card | High ticket value, booked in advance, personal credit limits are a real constraint |
| Software and subscriptions | Card | Recurring, predictable, and easier to audit on a dedicated card |
| Fuel and vehicle operating costs | Card | High transaction frequency, low value per transaction |
| Parts, supplies, and small procurement | Card (P-Card) | Faster than a purchase order for low-value orders |
| Mileage | Reimbursement | No transaction exists to capture |
| Home office, mobile, and internet | Reimbursement | The employee holds the contract |
| Occasional spend by infrequent travellers | Reimbursement | Card administration exceeds the claim volume it replaces |
The infrequent traveller case is more common than most comparisons admit. In a 1,000-employee organization across 16 sites where most staff file one or two reports a year, issuing 1,000 cards creates 1,000 reconciliation objects, 1,000 chances for a dormant card to be compromised, and an administration workload that dwarfs the claim volume it replaced. Reimbursement is the correct option there, not the legacy one.
The reimbursement side has a cost worth naming plainly. Every day a claim sits unpaid, an employee is lending the company money at zero interest. That cost appears on no line of your P&L, and it lands hardest on the employees least able to absorb it.
Corporate cards make close a reconciliation problem. Reimbursements make it a completeness problem. Knowing which failure you are buying is most of the decision.
Corporate cards
A reconciliation problem
With cards, your controller is matching a statement to posted transactions to receipts, and the friction shows up in specific, repeatable ways. Transactions that authorize before the statement cutoff and post after it land in the wrong period. Foreign purchases arrive as two lines, the charge and the foreign transaction fee, that both need coding. Merchant category codes describe the merchant rather than the expense, so a hotel charge that is really a conference room rental still gets recoded by hand. And a card transaction with no receipt attached is a reconciled line item with an audit hole in it, which is a worse position than an unsubmitted claim, because the money is already gone.
Reimbursements
A completeness problem
With reimbursements, the question is not whether the claims you have are coded correctly. It is whether the claims you have are all the claims that exist. An employee who incurs an expense in March and files it in June has put an expense in the wrong period, and no amount of careful coding fixes that after the fact. This is why the accrual matters more on the reimbursement side, and why a submission deadline in policy is doing accounting work, not just administrative work.
A company running both models without a single system runs both failure modes at once, usually in two tools with a spreadsheet between them.
Every company has a reimbursement floor, the irreducible volume of out-of-pocket claims that exists no matter how many cards are issued. Three things put a bottom under it.
Six US states impose a broad obligation to indemnify employees for necessary business expenses: California (Labor Code §2802), Illinois (820 ILCS 115/9.5), Montana, New Hampshire, North Dakota, and South Dakota. The obligation follows where the employee works, not where the company is headquartered, and issuing that employee a card does not extinguish it.
Reimbursements are excluded from taxable wages only if the expense has a business connection, the employee substantiates it within a reasonable period, and any excess advance is returned. Treasury Regulation §1.62-2(g) sets safe harbors of 60 days and 120 days. Miss one test and the arrangement becomes non-accountable, making the payments taxable wages reportable on the W-2.
A per-kilometre allowance is non-taxable only if based solely on business kilometres actually driven at a reasonable rate. For 2026 the prescribed rates are $0.73 per kilometre for the first 5,000 business kilometres and $0.67 after that. A flat monthly car allowance not tied to actual kilometres is a taxable benefit reportable on the T4.
Substantiation attaches to the expense, not to the payment instrument. Cards reduce data entry. They do not remove the documentation obligation, which is why "we issued cards so we stopped collecting receipts" is a finding waiting to be written up. For the mechanics of running the claims side properly, see how the employee expense reimbursement process works end to end.
ExpensePoint assumes most companies will run both models side by side permanently, so both live in one workflow rather than two systems that meet in a spreadsheet.
Most mid-market companies should run corporate cards for travel, subscriptions, fuel, and small procurement, and keep reimbursements for mileage, home office cost sharing, and occasional spend by infrequent travellers. The split depends on how concentrated your spend is and which jurisdictions you employ people in.
