Turn Supplier Catalogs into Profitable Purchase Orders. Fast
Wholesale moves fast. Your sourcing stack should too — from first look at a product to sent PO and active listings, without switching tools.
Trusted by Amazon sellers doing $10K–$500K+/mo
Research products and brands without switching tools
Margins, Buy Box, IP risk, and competitor data on any Amazon or supplier page — before a single email is sent.
Different sellers, same connected workflow
Wrong brand, wrong supplier, wrong COG — any one kills the deal
Right product, wrong supplier. Right supplier, wrong COG. Every tool catches a different one — and passes the data to the next step so nothing gets re-entered.
- Brand research before the first call
- Price list filtered to viable leads
- Lowest COG confirmed across suppliers
- PO built and sent in one click
Know the brand, the market, and the supplier before the price list arrives
Wrong brand, gated product, competitor already there. Answer those questions before you make contact.
Margins on any page, instantly
Buy Box share, IP risk, and price drops on any Amazon or supplier page. You never open a new tab.
Browser Extension →Find brands to sell
See revenue, Buy Box ownership, and Amazon's share across the full brand catalog, not just the ASIN you spotted.
What your competitors are stocking
Track any storefront over time. See what they add, drop, and how their catalog shifts — before it hits your margins.
Your next batch is buried in a supplier spreadsheet. Uncover it in minutes
Upload, match ASINs, filter by margin, clear restrictions. What's left is what you can actually order.
Get from price list to shortlist, fast
Upload, ASIN-match, filter by margin and competition, move to order. No manual lookups, no formula maintenance.
Price List Analyzer →Focus on opportunities you can actually act on
Check up to 20,000 ASINs at once. Restricted products are out before anything moves to a purchase order.
Find vetted suppliers for any brand
Locate reseller-friendly suppliers and verified distributors with contact details. Save them straight to your workspace.
The order comes after the research —
it shouldn't feel like starting over
Make sure you commit to the most profitable supplier. Data from your analysis carries into the PO — nothing re-entered, nothing looked up again.
Buy at best COG every time
See every supplier offering the same ASIN, with COGs and full history. Compare before you commit.
Products →Every supplier, one place
Manage every supplier in one place with contacts, business terms, products, price lists, and order history.
Shortlist to PO to listing, instantly
Easily turn your shortlist into a purchase order, then list your items right after. SKUs, costs, and shipping details transfer automatically.
Most of what costs you happens after you ship
List directly from your purchase order. Catch unit discrepancies while they're still claimable. Track your true cost, down to the inbound fee.
Bulk listing direct from purchase order
Select products, set condition and fulfillment, submit to Amazon. Errors surface with the exact failure reason — no guessing.
Lister →Catch missing shipment units early
Catch missing units on closed shipments immediately. File a manual claim with Amazon before the 60-day window closes.
Your actual landed cost, not an estimate
Unit cost, prep fees, and inbound charges pulled from your orders and shipments automatically. Weighted across every PO the SKU appeared in.
