The playbook is simple

01

Scan

Monitor warehouse club pricing, clearance events, and Instant Savings across Sam's Club, Costco, and BJ's. Surface deals with 50%+ ROI before the crowd finds them.

02

List

Push inventory across Amazon, Walmart Marketplace, and eBay simultaneously. Multi-channel means more buyers, less price compression, and diversified risk.

03

Profit

Track every SKU from purchase to sale. Know your real margins after fees, shipping, storage, and returns. Scale what works, cut what doesn't.

Built for operators,
not hobbyists

Most arbitrage sellers use spreadsheets and gut instinct. SpreadHawk treats reselling like a real business.

Price gap detection

Real-time spread analysis between source and sell prices across all major marketplaces. See the opportunity before it disappears.

Fee-aware profit calc

Amazon referral fees, FBA storage, Walmart commissions, eBay final value fees. Every cost accounted for. No surprise margin erosion.

Category risk scoring

Know which products are safe to sell and which will get you flagged. Brand gating, IP complaint history, and restriction probability scored per listing.

Multi-marketplace sync

List once, sell everywhere. Inventory synced across Amazon, Walmart, and eBay so you never oversell and always maximize exposure.

30% fewer arbitrage sellers on Amazon in 2026 vs 2024. Less competition for disciplined operators.
50%+ target ROI per item. Buy for $10, net at least $5 after every fee and cost. Below 30% isn't worth the shelf space.
3 marketplaces working simultaneously. Amazon for volume. Walmart for stability. eBay for long-tail.

The spread is the business.

Every retail shelf has mispriced inventory. Every online marketplace has buyers willing to pay more. The gap between those two prices is your revenue. SpreadHawk exists to find those gaps faster, exploit them across more channels, and turn a side hustle into a daily operation that compounds.

Warehouse clubs to marketplaces. Systematized.
