The short answer
Policy precedes technology
Before you implement any software, you must define the rules. What is the daily allowance for a hotel? Can they buy alcohol at a client dinner? Can they upgrade to first class on a train? If you do not write this down, employees will guess, and their guesses will be more generous than yours. A formal document provides clarity and sets expectations, reducing disagreements and potential misuse.
Your policy is a living document. As your business grows and changes, so will the requirements around employee spending. Regularly revisit the policy to ensure it reflects current operational and financial conditions. Engage your team when updating these rules to gain insights and to promote a shared understanding of any changes.
The policy does not need to be a lengthy legal document. A single page covering the five most common spending categories — travel, accommodation, meals, software, and client entertainment — is enough to eliminate 90% of the grey areas. Keep it short enough that people actually read it, and put it somewhere they can find it without asking HR.
Hard limits over soft guidelines
Telling an employee 'try to keep it reasonable' is a soft guideline that invites conflict. Giving them an expense card with a hard £100 daily limit is a technical boundary that requires no argument. Software should enforce the policy so you don't have to. This removes personal bias from decisions and empowers employees within agreed limits.
Hard limits make budgeting predictable and manageable. By understanding expenditure caps, you can better forecast monthly cash flows, and employees can plan their spending more efficiently. This not only curtails excessive spending but also builds a culture of fiscal discipline and transparency.
The psychological effect of a hard limit is also significant. When an employee knows their card will simply decline above a certain amount, they stop testing the boundaries. There is no awkward conversation, no judgement — the system just says no. That removes the founder from the role of financial police officer entirely, which is exactly where you want to be.
The receipt rule
Without a receipt, an expense cannot be claimed against tax, meaning it costs the business significantly more. The rule must be absolute: no receipt, no reimbursement (or the card gets frozen). Modern apps make this easy by prompting for a photo instantly. Having a clear, non-negotiable receipt policy simplifies audits and enhances trust with the financial team.
Receipts serve as proof of legitimate business expenses. When employees promptly submit receipts, they reinforce accuracy in financial reporting. This practice is vital for maintaining compliance with HMRC requirements and ensuring that your business minimizes taxable profits legitimately. A strong receipt culture improves transparency and accountability across the business.
The best time to capture a receipt is the moment the purchase happens, not at the end of the month. Expense platforms like Pleo, Soldo, and Moss send an instant push notification after every card transaction asking the employee to photograph the receipt. When the habit is built into the moment of purchase, the end-of-month reconciliation becomes a five-minute review rather than a two-hour archaeology project.
Reimbursement versus company cards
The traditional model — employees pay personally and claim back — creates a cash flow burden on your team and a reconciliation burden on you. An employee who pays £800 for a conference ticket on their personal card and waits 30 days to be reimbursed is effectively lending the business money interest-free. Over time, this erodes goodwill, particularly for junior staff who cannot easily absorb the float.
Company expense cards eliminate this entirely. The employee spends the company's money directly, the receipt is captured at point of purchase, and the bookkeeping entry is created automatically. The only thing left for you to review is the exception report — transactions that were flagged as unusual or that lacked a receipt.
Moving from reimbursement to company cards is one of the highest-leverage operational improvements a growing business can make. It saves hours of admin every month, removes the personal financial burden from employees, and gives you real-time visibility into where money is going rather than a retrospective surprise at month end.
Worked example: A clear expense policy excerpt
- Trains
- Standard class only, booked at least 7 days in advance where possible.
- Hotels
- Maximum £120/night outside London, £180/night inside London.
- Meals
- Maximum £30/day for evening meals when staying overnight.
- Client Entertainment
- Requires pre-approval from a director if exceeding £100.
This is an illustrative example, but clarity like this prevents employees from feeling anxious about what they can spend, and prevents founders from feeling exploited. By spelling out these expectations, you create a transparent baseline that supports fair spending while aligning with business cost objectives.
What to do, in order
- 1
Draft a one-page policy
Keep it simple. Cover travel, accommodation, meals, and software subscriptions. This document should be concise yet comprehensive enough to outline key spending areas and limitations, while remaining easily understandable for all employees.
- 2
Distribute individual cards
Use a modern expense platform to give each spender their own card with a hard limit. This empowers employees to make purchases within set parameters while streamlining spending controls. The individualized approach reduces the risk of misuse and simplifies the reconciliation process.
- 3
Enforce the receipt rule ruthlessly
If an employee fails to upload receipts for three transactions, freeze their card until they do. They will only make the mistake once. This approach encourages prompt compliance and ensures that every transaction is verifiable, supporting accurate financial record-keeping.
Common mistakes
- Having an unwritten policy that exists only in the founder's head. This leads to inconsistency in enforcement and potential disputes over what constitutes appropriate spending, increasing the risk of financial leakage.
- Allowing senior staff to ignore the receipt rules, which destroys the culture of compliance for everyone else. This undermines the integrity of your policy and sets a double standard that can demotivate employees and erode trust in leadership.
- Reviewing expenses manually at the end of the month rather than using software to flag anomalies automatically. This method is time-consuming, prone to human error, and less effective than real-time monitoring. Manual reviews can delay corrective measures, increasing financial risks.
- Overcomplicating the policy with too many exceptions. Complex rules confuse employees and make compliance more challenging, often leading to mistakes or intentional end-runs around the policy.
- Neglecting to update the expense policy as the business evolves. This can result in outdated rules that no longer reflect the company's financial goals or operational realities, leading to inefficiencies and financial strain.

Frequently asked questions
- Can I deduct the cost of un-receipted expenses from an employee's salary?
- Only if their employment contract explicitly allows for it, and even then, it is legally complex and terrible for morale. It is much better to use prepaid cards and freeze them if receipts are missing. This approach protects employee relations and ensures clearer expenses management.
- What should I do if an employee consistently overspends their limits?
- First, ascertain why the overspend occurred. It may be a genuine misunderstanding or a sign of inadequate limits. Discuss the incidents with the employee and adjust the spending limits if required. Repeated offenses should lead to a more formal review, possibly involving HR.
- How can I encourage employees to follow the receipt rule?
- Implement an easy-to-use system that makes receipt submission simple, such as a mobile app that allows them to photograph receipts instantly. Recognize employees who consistently follow the policy and provide positive reinforcement publicly. Reinforce the importance of this rule during team meetings and through internal communications.
- Is there a benefit to allowing some flexibility in the expense policy?
- While structure is important, allowing for some flexibility can be beneficial in certain situations, like last-minute travel changes or emergencies. However, flexibility should be the exception rather than the rule and should be documented to prevent abuse and maintain transparency.
