Name: SellerRadar
Brand: SellerRadar
Price: 49 USD

SellerRadar diffs every Amazon fee-schedule change — referral, FBA fulfillment, and storage — against YOUR catalog. Upload a seller CSV export and get the dollar impact per SKU per year, not another dashboard of charts.

What you get

Sellers already pay for tools that show them data. Nobody tells them the dollar impact of a fee change on their own catalog. SellerRadar does exactly one thing: change → impact → alert.

Upload your catalog

A CSV export with SKU, category, dimensions, weight, COGS, price, and estimated monthly units. Flexible header mapping — real Seller Central exports parse as-is. No Amazon credentials, no SP-API.

We diff the fee schedules

Every fee row is versioned with its source URL and effective date. We compute your per-unit fee stack before and after the change — referral %, FBA fulfillment by size/weight tier, and monthly storage.

You get dollars, not data

"This change reduces your margin by X% on Y SKUs, estimated $Z/year." Per-SKU breakdown in the $49 audit; the $99/mo monitor re-scans weekly when schedules update and emails your personal impact.

Fee changes we track

The three Amazon fee types covered in v1 — every schedule row carries a source URL and effective date. Your audit computes the delta against your own catalog.

Type 01

ReferralReferral fee % changes by category — a 1-point move on apparel reprices every unit you sell

Referral

Type 02

FBA fulfillmentSize/weight tier repricing — a few cents per unit compounds to thousands per year at volume

FBA fulfillment

Type 03

StorageMonthly storage rate moves per cubic foot — quiet, recurring, and easy to miss

Storage

v2Inbound placement fees, aged-inventory surcharges, and PPC cost analysis (post-MVP scope)

Spotlight

Amazon bumped fulfillment fees in February and my "profitable" SKU was suddenly break-even. I found out from my accountant in April. A dollar number per SKU the week the fee changed would have saved me a quarter of dead pricing.
