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.

  • 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. The free tier is genuinely free — no card, no trial period, no automatic charges. You only enter payment info when you decide to upgrade to Pro or Growth.
What eBay data does Zellerly pull? +
Everything that flows through eBay's API — active listings, completed sales, transaction fees, shipping data, and item details. Your full history is imported the moment you connect, all the way back to your first sale.
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: equity curves, trending sourcing data, tax tracking, and cash flow projections.
Does this work for any eBay category? +
Yes. The dashboard is category-agnostic. All analytics, KPIs, equity curves, and goal tracking work the same whether you sell clothing, electronics, collectibles, sneakers, or anything else on eBay. The What's Hot tab surfaces trending data across all eBay categories too.
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.
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.
