Haul Yield Tracker

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.

The Real Profit Engine

eBay has your real numbers. It just makes you go find them — fees in one report, shipping costs in another, sales in a third, then do the math yourself. Zellerly pulls all three together automatically, the moment you open your dashboard, and reconciles them down to the penny. No digging through reports. No spreadsheet math. And unlike a static report, those same real numbers feed straight into your daily goals and rewards, something a report was never built to do.

Exclusive to Zellerly
AI That Writes Listings That Sell

Stop staring at a blank title field. Snap a photo, and Zellerly builds a Cassini-optimized title, a full set of item specifics, and a description engineered for both search engines and AI answer engines — AEO and SEO in one pass — so your listing shows up whether a buyer's typing a search or asking an AI to find it for them. What used to take fifteen minutes takes fifteen seconds.

Built for eBay's Cassini algorithm + AEO
🎮
Momentum, Engineered

Consistency is the real unlock in reselling, and it's the hardest thing to sustain alone. Daily goals, real streaks, and rewards tied to your actual sales — not busywork — turn showing up every day into something that feels like progress instead of a chore.

Zelly, The Coach Who Actually Knows Your Business

Most reseller advice is generic — the same five tips repeated everywhere. Zelly is different: it learns from your real sales, real profit margins, and real performance trends, then delivers daily, weekly, and monthly coaching built specifically around your store. Not what worked for someone else. What's actually working, and not working, for you.

Growth feature · Powered by AI
The equity curve

  • Tracks cumulative profit from your first sale forward
  • Daily, weekly, monthly, quarterly, yearly, and all-time views
  • Best month, average month, and days active — always visible
  • Updates automatically every time a sale comes through eBay

Questions

Everything you want to know

Do I need a credit card to start? +
No. Every new account starts with a free 14-day Growth trial — no card required. After the trial, you're automatically moved to the Free tier unless you choose to upgrade. You're never auto-charged.
What eBay data does Zellerly pull? +
Everything that flows through eBay's live API — active listings, completed sales, transaction fees, shipping data, and item details. eBay's own API only exposes about 90 days of order history, a platform-wide limit that applies to every developer, not something we control. Zellerly captures what's available at connection, then keeps building your real history forward from there, permanently. The longer you use it, the deeper your history goes.
How is this different from Vendoo or List Perfectly? +
Vendoo and List Perfectly are cross-listing tools — they help you post items to multiple platforms. Zellerly is a performance analytics platform built specifically for eBay sellers who want to understand and scale their business. Different tools, different jobs. We do what they don't: real fee and shipping reconciliation, sourcing intelligence built from your own sales history, and tax-ready reporting.
Does this work for any eBay category? +
Yes. The dashboard is category-agnostic. All analytics, KPIs, growth charts, and goal tracking work the same whether you sell clothing, electronics, collectibles, sneakers, or anything else on eBay. Sourcing Intel highlights your own best-performing brands and categories, so it gets sharper the more you sell, in any category.
Is my eBay data secure? +
Yes. We connect via eBay's official OAuth 2.0 API — the same method used by every major eBay integration. We never see or store your eBay password. You can revoke access at any time directly from your eBay account settings.
What is AEO, and why does it matter for my listings? +
AEO (Answer Engine Optimization) is how content gets surfaced by AI shopping assistants like ChatGPT Shopping and Perplexity — the same way SEO gets you found on Google. It rewards specific, structured, quotable facts over vague marketing language. Zellerly brings AEO to your eBay listings, starting with your Condition and Description fields, so your listings are ready for where shopping is heading, not just where it's been.
How do Daily Plays and points work? +
Every day, Zellerly ranks the highest-impact actions for your store — send an offer, reprice a stale listing, refresh cold photos — by real dollar value. Complete one, earn points automatically. Points redeem for real billing discounts (up to 20% off) or a 24-hour Zelly AI Coach pass. Streaks and personal records earn bonus points and get celebrated the moment you hit them.
Can I cancel anytime? +
Yes, anytime, no questions asked. Cancel from your account settings in 10 seconds. You keep access through the end of your billing period. Annual plans are non-refundable for unused months but you can cancel renewal at any time.
