## Questions

### Should I choose Quartile or Atomic One for advertising across multiple channels?

Quartile is the better fit for cross-channel advertising: it publishes support for Amazon Ads, Walmart Connect, Google Ads and other channels. Atomic One describes an Amazon-focused operating system and says Walmart support for its MCP is on the roadmap.

### Which product covers more than Amazon PPC?

Atomic One publishes Amazon agents for PPC, pricing, listings, inventory, fees and promotions. Quartile also publishes promotion and listing optimization services, but its core offering is cross-channel advertising management.

### How much do Quartile and Atomic One cost?

Neither Quartile nor Atomic One publishes a standard price for its paid service. Quartile specifies fees in an order form, while Atomic One invites buyers to book a demo. Atomic One separately offers a free Amazon MCP connection; that is not the same as its paid agents.

### Is Atomic One's free MCP the same as its paid agents?

No. Atomic One's free MCP connects Amazon store data to supported AI tools for analysis. Its agents are a separate paid layer that performs ongoing store operations.

### Can I use either product with ChatGPT?

Atomic One publishes an MCP connection for ChatGPT, as well as Claude and Codex; ChatGPT requires a paid plan to use connectors. Quartile does not publish an equivalent Seller Central-to-AI-tool connection.

### Do both products include human support?

Quartile says every customer receives dedicated account support from an advertising team. Atomic One describes a dedicated strategic advisor alongside its agents and on-call specialist teams.

### What commitment does Quartile require?

Quartile's published terms describe an annual contract, with a 60-day initial evaluation period and a month-to-month exception available only if Quartile grants it in writing. Atomic One does not publish a paid-service contract term.

### Which Amazon marketplaces does Atomic One's free MCP support?

Atomic One says its free MCP is live for Amazon stores selling in the US and Canada, and for eligible Mexico sellers using Amazon.com with inventory in the US. It lists the UK and Germany as coming soon.
