About SellerMonitor

SellerMonitor is a real-time analytics platform built for Amazon FBA sellers and the agencies that serve them. We unify profit, inventory, and competitor data across every Amazon marketplace into a single dashboard — so you can act on accurate numbers instead of guessing.

We connect through Amazon’s official Selling Partner API (SP-API) with secure, read-only access, surface the metrics that move your business — true margin per SKU, Buy Box status, stockout risk, PPC RoAS — and alert you the moment something changes.

Operated by FBA Seller Inc., SellerMonitor is built to deliver enterprise-grade monitoring at a fraction of the cost of legacy tools, without the bloat or steep learning curve. We are based in Vancouver, Canada, and serve Amazon sellers worldwide.
