We would like to hear from you, whether you have found a fee that has changed, have an idea for a new tool or have a question about how a tool works.

Before you write

• Fee corrections: please include a link to the official page that shows the new fee, if you can.
• Account problems: we cannot access or change your marketplace account. For orders, payments or account issues, contact the platform's own support team.
• Advice: we cannot give personal financial, tax or legal advice, but we are happy to explain how our calculators work.

We usually reply within a few working days.
