Staxly - Reseller Margin Checker

See your real profit before you list — works on major reseller marketplaces.

Staxly shows you the real profit on any listing before you commit to selling it. A floating button appears right on the page when you’re listing on a reseller marketplace — tap it to see sale price, your cost, shipping, and platform fees calculated into instant profit, margin %, and ROI. Fee percentages are pre-set per platform and fully editable, so the numbers stay accurate to how each marketplace actually charges you. Works across most major resale and marketplace sites. Built for resellers who list across multiple platforms and need to know their real margin at a glance, not after the sale.
