Finally shipped the tool I kept wishing existed as an ecommerce seller
Hey everyone 👋
No promo, just sharing something I've been quietly working on for a while.
I've been selling on Amazon, eBay, and Etsy for years — and every time a platform changed their fee structure, I'd find myself rebuilding the same spreadsheet from scratch at 11pm wondering where my margins went. Got tired of it.
So I finally just... built the thing. A free set of ecommerce fee calculators. Amazon FBA, Etsy, Shopify, Stripe, PayPal, eBay, ROAS, profit margin — all in one place, all updated for 2026 rates. No login. No email wall. Just plug in your numbers and get an answer.
It's not fancy. It's not trying to be the next big SaaS. It's just the tool I wished existed when I started selling.
If anyone has a spare 2 minutes to poke around and tell me what's broken, missing, or just plain confusing — I'd genuinely appreciate it 😅 Thick skin, promise.
