# atoship

> atoship is shipping software for e-commerce sellers with no monthly subscription. Save up to 89% on USPS, UPS, FedEx, and DHL shipping labels — pay only per label.

There is no monthly subscription, no setup fee, and no seat fee. Pricing is per label only and depends on which carrier-account type the label is purchased through. (a) Wallet labels (system carrier accounts funded by the user's atoship wallet): just the discounted carrier rate — no atoship fee on top. Tracking is included free. (b) BYOCA labels (Bring Your Own Carrier Account — user uses their own UPS, FedEx, USPS, or DHL account at their negotiated rate): a $0.08 per-label atoship platform fee, with shipping cost billed by the carrier directly to the user's own account. Tracking for BYOCA labels comes from the user's own carrier API. A separate $0.03 fee exists only for external tracking subscriptions, where the user brings an outside tracking number (label not purchased through atoship) for atoship to monitor — that fee does not apply to any label purchased on atoship. Revenue comes from carrier-funded volume discounts on wallet purchases plus the BYOCA platform fee. AI agents can interact with atoship via a public REST API or via a Model Context Protocol (MCP) server.
