Amazon FBA Analytics Software Built by Sellers, for Sellers
SellerLegend delivers profit tracking, inventory management, and sales analytics for Amazon sellers. Get the data-driven insights you need to grow your FBA business across NA, EU, and FE Amazon marketplaces.
Why We Built SellerLegend
As former Amazon FBA sellers, we struggled with inaccurate profit calculations, manual spreadsheet tracking, and fragmented data across marketplaces. Amazon Seller Central doesn't show your true profit after FBA fees, advertising costs, and returns. That's why we built SellerLegend - to give Amazon sellers accurate, frequent profit analytics and the tools needed to make smarter business decisions.
Accurate Profit Calculations
We automatically calculate your true Amazon profit by factoring in FBA fees, advertising costs, returns, promotions, and all other expenses that Seller Central doesn't show you.
Built for Amazon Sellers
Every feature is designed specifically for FBA and FBM sellers. We understand the challenges because we've lived them ourselves.
Always Up-to-Date
Order data syncs every 30 minutes from Amazon. Other data types refresh hourly to daily. No manual imports, no spreadsheets — just trustworthy analytics.

Common questions about SellerLegend Amazon analytics software
SellerLegend is an Amazon FBA analytics and profit tracking software that helps sellers understand their true profitability. We connect directly to your Amazon Seller Central account and automatically calculate your net profit after all fees, advertising costs, and expenses.
We pull data directly from Amazon's API and calculate your true profit by subtracting all costs: FBA fees, referral fees, advertising spend (PPC), returns, refunds, promotions, shipping costs, and any custom costs you add. This gives you accurate, frequently-updated profit visibility that Seller Central doesn't provide.
SellerLegend supports North America (US, Canada, Mexico), Europe (UK, Germany, France, Italy, Spain, Netherlands, Sweden, Poland, Belgium, Turkey), Far East (Japan, Australia, Singapore, India), Middle East (UAE, Saudi Arabia, Egypt), and South America (Brazil) Amazon marketplaces.
SellerLegend syncs your Amazon order data every 30 minutes. Other data types refresh on different cadences: finances every 1–3 hours, inventory every 8 hours, currency rates every 6 hours, listings and feedback daily, settlements weekly.
