Policy changes have real money consequences
We quantify impact when possible. When official figures aren't available, we say so — we never guess.
Quantified alerts in our database
Policy intelligence, not policy noise
Seller Policy Radar is a monitoring service for Amazon and TikTok Shop sellers. We turn policy changes into actionable business intelligence.
Daily Policy Scanning
We monitor official Amazon and TikTok Shop policy sources every day — not just when something trends on social media.
Official Source Verification
Every alert links to the original policy announcement. No secondhand reporting, no Chinese media paraphrasing as primary source.
Plain English Translation
Marketplace policy language is written for lawyers. We rewrite it for sellers: what changed, who's affected, what to do.
Money Impact Quantification
When official numbers exist, we calculate the per-order or per-SKU cost change. When they don't, we say NOT_QUANTIFIABLE.
Confidence Scoring
HIGH / MEDIUM-HIGH / MEDIUM — you always know how certain we are about a given alert before you act on it.
Recommended Actions
Not vague guidance. Specific steps: which tools to check, what to recalculate, and what deadline you're working against.
Simple, transparent pricing
One plan. Everything included. Cancel anytime.
