Track every sale. Spot every trend. Hit every goal. The only analytics platform built specifically for eBay sellers — with a live equity curve, daily trending items, and a tax tracker your accountant will thank you for.
Every feature solves a real problem — whether you're building your first 100 listings or scaling past 2,000. One platform, every stage.
Watch your cumulative profit climb from day one. The only reseller tool with a real equity curve — because your business deserves to be treated like the investment it is.
Know exactly which brands and categories are trending on eBay before your next sourcing run. Stop guessing, start sourcing with data that updates every 24 hours.
Score your listing titles for eBay SEO before you post. Get specific, actionable fixes — brand, size, color, material, style — that get your items seen and sold faster.
Never get blindsided by a tax bill. Track your self-employment tax reserve in real time with a live quarterly countdown so you're always prepared.
Items sitting 45+ days with no sales get flagged automatically. Reprice before they die. One feature that pays for the subscription on its own.
Your personal AI coach that knows your store data. Get daily, weekly, monthly, and yearly insights pushed to you — plus a chat interface to ask anything about your business.
Every sale broken down — sale profit, shipping profit, and all eBay fees tracked per item and across every time period. See your real net profit down to the penny.
Log every sourcing run, track your true COGS, and see your shipping profit broken out separately — because the $3+ you make on every shipment is real income that most sellers never track.
A single line that tells the whole story — every sale, every week, every month, climbing from day one. When it's going up you feel it. When it flattens you fix it. No spreadsheet gives you this.
Real-time trending data pulled from eBay's marketplace every day. See which brands are moving fastest, at what price, and in which categories — so every sourcing decision is backed by data, not gut feeling.
No complicated setup. No spreadsheets. No manual data entry. Just connect and go.
Sign up in 30 seconds. No credit card. No commitment. Start with the free tier and upgrade when you're ready.
One-click OAuth connection. We pull your full history — sales, fees, listings — all the way back to day one. Nothing to enter manually.
Your equity curve populates instantly. Goals activate. Stale alerts fire. What's Hot refreshes. Your dashboard is live.
Every plan includes real eBay data, real analytics, and zero hidden fees. Upgrade or downgrade anytime.
All plans include a real eBay API connection, full historical data import, and multi-device access. No setup fees.
