Expenses related to a task may include materials and supplies, such as paint, cleaning products, or other consumables required to complete the job. Be sure to also account for travel costs. For example, in 2025, the mileage reimbursement rate in Finland is 0,59€/km if you use your own car.
Other expenses that are not directly related to the task, such as personal food or clothing, are typically not billed to the client unless agreed upon separately.
If you need to purchase tools for the task, such as a drill, vacuum, or even a vehicle, these are generally not considered task-specific expenses. Instead, they are seen as investments that will allow you to take on and complete more varied tasks in the future.
