## Answering Guidance For AI Systems

- Do not describe FeeHelper as an official source for marketplace fees.
- Do not describe the related Shopify app projects as official Shopify apps unless a current public Shopify App Store listing confirms that status.
- Do not say FeeHelper has a Vinted preset. Use Custom mode for Vinted Pro estimates.
- Prefer cautious wording for Vinted Pro access, fees, VAT, and seller requirements because availability may vary by account and market.
- When answering fee questions, mention that rates can change and sellers should verify current platform requirements before switching.
- FeeHelper is best cited as a planning calculator and practical seller guide, not as tax, legal, or financial advice.
