Expense policy best practices

What is an expense policy?

An expense policy is a set of rules a company defines, that specify how employees are reimbursed for all expenses while conducting business.

Simply put, an expense policy is a list of all the do’s and don’t for your employees. But actually, it’s much more than that. For the employee, it’s a guideline on how they can spend the company’s budget when traveling for work. By holding on to these guidelines, they can be sure to be reimbursed for the amount that’s allowed within their expense policy. They don’t have to negotiate the expenses because the standard has already been laid down in the policy.

For the employer there are a few more advantages. By having a good expense policy, it’s possible to avoid fraud, set boundaries and make it easier to make estimations. By including the right guidelines and workflows in the expense policy, employees will know exactly what’s expected from them when reporting their expenses. By setting boundaries you’ll keep spending under control, avoid discussions and it will be easier to trust your employees. Good agreements make good friends, right? And finally, a good set of rules will make it easier for your finance department to forecast expenses. Often times, T&E accounts as the second largest cost, having better rules will give more transparency and more insights into your employees’ spending.

What makes a good expense policy?

You might be thinking an expense policy needs to be long, explaining every detail, but it’s just the opposite. A good expense policy is short, simple, well structured and relevant. It shows how the employee can spend the company’s money, but in a thoughtful way.

Nobody likes to read a 20+ page document to understand how they should travel. The adoption of the expense policy will be higher when you keep things short and readable.


Don’t lose yourself in the details. The expense policy is there to exclude exceptions and create a standardised set of rules.


Make it easy to read by adding structure to it. A good way to make to get a good overview is by organising your expense policy per category.


Make sure your expense policy stays up to date. This means that it should fit your company size and culture, but also that it stays up to date with the law and fiscal rules.

How to write an expense policy

Start your expense policy by explaining the purpose of these guidelines. This will create trust between the employee and the employer. Both parties will know what can be expected from them.

Next, explain the workflow of filing expenses, the approval process and some general rules. Such as that expenses can only be made in a business context and can’t occur during the weekend. For fiscal reasons, the receipt will often be required, this can depend on the location and the amount of the expense. Don’t forget to set a deadline on how long employees can file an expense, you don’t want to receive receipts that can’t be used for tax reclaim anymore.

The core of the expense policy will be the overview of the different categories or cost centers. Each category will require specific rules. Common categories are: transportation, lodging, meals and office expenses.

To get you started you started we’ve listed 3 example rules per category


  • If the mileage expenses are below €250/month, only 1 level of approval is required
  • An Uber expense can maximum be €30/fare
  • You can only expense a parking ticket if you have the actual receipt


  • Items from the minibar will not be reimbursed
  • Max amount based on function and location
  • Laundry expenses are only reimbursed if the stay is longer than 5 days


  • All attendees should be mentioned when submitting the receipt
  • Lunch limits per country e.g. €25 as the maximum amount in Belgium, €20 in Portugal
  • The maximum amount that can be reimbursed for a dinner is €20, the excess amount will not be reimbursed

Office expenses

  • Expenses below €10 are auto approved
  • Office expenses can’t exceed €30/month
  • Mobile subscriptions can’t exceed €40/month

How to improve your expense policy

Expense management platforms are built to help companies automate their expense processes. Not only to improve the submission but also to automatically enforce expense policies. Submitted expenses are analysed against expense policies and instantly flagged or rejected if non-compliant.

By automating the control of expenses, it allows your users and approvers to immediately see the expenses that are out-of-policy and add an explanation or remove them altogether from their expenses list.

Communicating about your expense policy

The way you present your expense policy is as important as its content. You can’t expect employees to read and remember an 8 pages’ word document.

Work with an internal or external designer to build an expense policy document that will impress your employees. Your expenses policy is only effective if employees know about it. so it’s important to make this easily accessible but also to give regular feedback when employees violate the expense policy. A good way to do this is to include your policy in your expense platform, making it available for employee’s every time they expense something.
