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.
SellerRadar Audit, USD 49 one-time
The full per-SKU breakdown, built for the moment you reprice or renegotiate.
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.
| Fee type | What changes | Status |
|---|---|---|
| Referral | Referral fee % changes by category: a 1-point move on apparel reprices every unit you sell | Tracked |
| FBA fulfillment | Size/weight tier repricing: a few cents per unit compounds to thousands per year at volume | Tracked |
| Storage | Monthly storage rate moves per cubic foot: quiet, recurring, and easy to miss | Tracked |
| v2 | Inbound placement fees, aged-inventory surcharges, and PPC cost analysis (post-MVP scope) | Coming |
You get dollars, not data
"This change reduces your margin by X% on Y SKUs, estimated $Z/year." Per-SKU breakdown in the audit (USD 49 one-time); the monitor (USD 99 / month) re-scans weekly when schedules update and emails your personal impact.
Impact figures are estimates, verify against your settlement reports. No financial, tax, or repricing advice.
