How it works
Drop the supplier's Excel or CSV. SourceVault detects UPC, ASIN, cost and stock columns and shows you a sample of each so you can fix the mapping.
.xlsx · .xls · .csvEvery product is looked up on Amazon: Buy Box, referral and FBA fees, profit, ROI, max cost, sales rank, sellers, restrictions, hazmat and IP risk.
Amazon SP-API + KeepaMark each product Winner, Discard or Review with one key. Winners move to the Research Lab, where you check them calmly and approve them for purchase.
G · D · R shortcutsBuild the purchase order with quantities, freight and prep spread into a landed cost, negotiate a discount and watch the order's profit and ROI update live.
Landed cost per unitAnalysis Center
Before you open a single product, SourceVault totals the catalog's monthly potential and breaks it down by category, brand and product.
Purchase orders
Freight, prep, tax and labels are spread into each unit's landed cost, so the profit you see is the profit you make.
Browser extension
The SourceVault panel opens next to any amazon.com product: type your cost and see profit and ROI instantly, or see the max cost you can pay when you don't know it yet.

Built on official data
Prices, fees, restrictions and catalog data come from Amazon's Selling Partner API, not from scraping pages.
Amazon and Keepa keys are stored encrypted. The extension uses its own token that you can revoke at any time.
Every user signs in with an authenticator app. Admin, research, purchasing and viewer roles keep the team in its lane.
