Before you email
Quick answers to common questions.
The fee rate in your calculator doesn't match what eBay/Etsy/etc shows me.
Fee structures vary by seller status, category, and country. Check if our calculator has Advanced Options that match your situation (Top Rated Seller, eBay Store, seller country). If you still see a mismatch, email me with details.
Can you add [platform X] calculator?
Probably yes, but it depends on search volume. Email me which platform and I'll add it to the roadmap. Priority goes to platforms with more seller demand.
Do you offer paid features?
Not yet. All calculators are 100% free forever. We're building a paid multi-channel profit tracker for sellers on 2+ platforms — see pricing for early access.
Can I contribute or write for your blog?
Yes! Email me with a topic idea and your experience. We pay for quality guest posts about seller fees, platform comparisons, and profit optimization.
