Employee Expenses
Expenses are where small teams quietly lose money, goodwill and month-end evenings. This hub covers the policy first, then the mechanism: reimbursement, debit expense cards, prepaid cards or business credit cards, and the trade-offs of each.

Overview
Why expenses are a fairness issue before a finance issue
When a team member pays for a train ticket, a client lunch or software on their own card and waits weeks to be reimbursed, they are effectively lending the business money without being asked. This is easy to overlook because it feels like routine administration rather than a real cost to someone else.
Treating expenses primarily as a fairness question — is anyone out of pocket, and for how long — tends to produce better decisions than treating them primarily as a control question. Controls still matter, but they should sit on top of a policy that treats staff reasonably.
Getting this right also protects the business: a written policy and a sensible mechanism reduce disputes, prevent misunderstandings about what is claimable, and make it easier to spot genuine misuse when it happens.
The order to work through it
Start with the policy, not the product. Decide what can be claimed, what cannot, what evidence is required, and how quickly claims will be paid, before choosing between reimbursement, debit cards, prepaid cards or credit cards.
Once the policy exists, choose the mechanism that fits how often your team incurs costs. Frequent, predictable spending suits a card; rare, low-value costs can reasonably stay on reimbursement without causing hardship.
Finally, build in receipt capture and mileage handling as routine habits rather than end-of-month scrambles — ideally captured digitally at the point of purchase, using HMRC's approved mileage rates for any travel by personal vehicle.
Common failure modes
In Kayley's experience, the most common failure is having no written policy at all, so every claim is negotiated individually and inconsistently, which erodes trust over time even when no single decision was unreasonable.
A second failure is defaulting to reimbursement for frequent, work-critical spending, effectively asking staff to fund the business's short-term cashflow whenever a claim is delayed.
A third is having no plan for card misuse before it happens, so a genuine mistake or a deliberate abuse both get handled inconsistently, without a proportionate, pre-agreed response.
What to write down
Write a one-page expense policy covering scope, allowable and non-allowable costs, evidence requirements, claim timescales, mileage handling, and what happens in the event of misuse.
Set out your receipt capture expectations clearly — what counts as adequate evidence, how it should be submitted, and how long records need to be kept, in line with HMRC's requirements.
If you use expense or credit cards, document individual limits, who can adjust them, and how quickly access is removed when someone leaves or changes role.
What "done" looks like
No team member is meaningfully out of pocket for more than a few days for a legitimate work expense, and everyone can point to the same written policy when a claim is queried.
Receipts arrive close to the point of purchase rather than being chased at month-end, because capture is built into the mechanism you have chosen rather than left to memory.
You have a written, proportionate response ready for card misuse before it happens, so a genuine incident is handled calmly and consistently rather than improvised under stress.

Do I need a written expense policy for a team of three?
Yes, and it can be one page. A written policy prevents most disputes and gives you something fair to point to when a claim is refused.
Are expense cards better than reimbursement?
They are better when purchases are frequent, or when asking staff to pay first would be unfair. Reimbursement remains reasonable for occasional, low-value costs. The Employee Card Comparison Tool sets out the trade-offs.
What mileage rate should I pay?
HMRC publishes approved mileage allowance payment rates. Paying at or below the approved rate keeps the payment free of tax and National Insurance. Check the current rates on GOV.UK before setting your policy.
