Why sellers switch to Nexa Source
Sourcing tools are powerful but scattered. Nexa Source puts the whole decision — buy it, at what price, on which marketplace — on one screen, starting at $23/mo.
Amazon and Walmart, side by side
Most tools pick one marketplace. Nexa Source prices every product for both, including WFS and FBA fees, so you see which channel actually pays more.
Answers in seconds, not spreadsheets
Paste an ASIN, UPC or Walmart item ID and get profit, ROI, competition, restrictions and the cheapest source instantly — no CSV exports or scan queues.
Gating and risk flagged up front
See if a product is ungated, gated or hard gated — and what it takes to get approved — before you spend a dollar on inventory.
Real listings, refreshed live
Every row is a real Amazon or Walmart listing with current price, rating and offer count. No stale sample data, no invented products.
7 days
Free trial on every plan, no card games — cancel any time, and keep your saved products and alerts.

Built to be trusted with your buying decisions
You are spending real money on inventory. Here is exactly where the data comes from and how your account is handled.
Real listings only
Every product row is a live Amazon or Walmart listing with its current price, rating and offer count. Nothing is sample or placeholder data.
Refreshed continuously
Prices, ranks and offer counts are re-scanned throughout the day, and each product shows when its data was last pulled.
Transparent fee math
Profit is shown as a full breakdown — referral fee, FBA or WFS fulfilment, shipping and your cost — so you can check every number yourself.
Secure accounts
Sign in with email, Google or Apple. Sessions are encrypted, and your saved products, alerts and supplier lists are private to your account.
No lock-in
Start with a 7-day trial, change or cancel your plan any time, and keep access to your saved data on the free tier.
Verified sources
Supplier and arbitrage links point only to 44+ vetted retailer and distributor domains — never scraped or unverified sellers.
Nexa Source is an independent research tool and is not affiliated with Amazon or Walmart. Estimates are guidance, not guarantees — always confirm fees and restrictions in your seller account.
