Questions about a calculator, spotted an error in a guide, or want something built that doesn’t exist yet? Get in touch.

What I can help with

Something’s wrong in a guide. eBay changes fees and policies regularly, and sometimes a guide falls behind before I catch it. If you’ve spotted a figure that no longer matches what eBay is charging you, tell me — include the page and what you’re actually seeing, and I’ll check it against the current documentation.
A calculator isn’t working, or the numbers look off. Let me know which calculator, what you entered, and what you expected. Browser and device help too, since some issues only show up on certain setups.
You want a tool that doesn’t exist. An Amazon fee calculator is planned. Etsy and TikTok Shop tools are further out. If there’s a calculation you keep doing manually in a spreadsheet, that’s usually a sign it should be a tool — tell me what it is.
General feedback about the site. If something was hard to find, badly explained, or didn’t answer the question you came with, that’s worth knowing.
Guest posts, link exchanges, or paid placements. Short answer: no. The site doesn’t sell links or publish sponsored content, and that isn’t going to change.

What I can’t help with

I’m not eBay, and I can’t access, restore or influence your account. If you’ve been suspended, hit a selling limit, or had a case decided against you, only eBay can resolve it — though the guides on those topics explain the appeal routes that actually work.
I also can’t give tailored financial, tax or legal advice. The guides explain how the systems work; what to do about your specific situation is a question for a qualified professional in your country.
