Four public datasets, continuously maintained.

Tangible data assets you can search, filter, and reference — not gated reports or vague summaries.

Searchable rate cards across Amazon, Walmart, and Shopify. Referral, fulfillment, storage, and ad fees — all sourced from official documentation.

Historical and upcoming fee changes with impact levels, affected categories, and direct links to official announcements.

Appeal templates, policy references, and successful reinstatement strategies for common suspension types.

Continuously archived policy updates from official sources. Track what changed, when it took effect, and who it impacts.

We don't sell leads to marketplaces. Our datasets exist to protect your margin and your account.

Every record is traceable to a primary source — no speculation, no recycled blog content.

Data you can act on immediately. Filter by marketplace, category, date, or impact level.

Search the fee database or browse the latest policy changes — no signup required.
