EasyPost is a multi-carrier shipping API that lets businesses compare rates, buy and print labels, verify addresses, track shipments, and insure parcels across 100+ carriers through a single REST integration. Rather than building and maintaining a separate connection to each carrier (USPS, UPS, FedEx, DHL, Amazon Shipping, and many regional carriers), companies route all carrier interactions through EasyPost's standardized API. The platform is aimed primarily at e-commerce sellers, marketplaces, 3PLs, and software platforms that need to embed parcel shipping into their own applications or fulfillment workflows.
The product is delivered as a developer-first API with helper libraries for Python, PHP, Ruby, Node.js, Java, and other languages, alongside a web dashboard for account management and reporting. Core APIs include the Shipping API (rating, label purchase, manifests, customs), the Address Verification API, the Tracking API (real-time updates, branded tracking pages, webhooks), and the Insurance API. EasyPost also offers higher-level products such as Luma (AI-driven rate shopping and carrier selection trained on historical shipment data), Forge (a white-label, no-code shipping toolkit for platforms), and GlobalShip for enterprise scaling. The company reports enterprise-grade reliability with 99.99% uptime.
For ERP buyers, EasyPost functions as a parcel-shipping and carrier-rating layer rather than a full enterprise TMS for freight and multi-modal logistics. ERP integration is generally API-based: orders flow from the ERP to EasyPost for rate-shopping and label creation, and tracking numbers and statuses flow back. EasyPost publishes a validated native connector for Acumatica via the Acumatica xRP platform; NetSuite and most other ERPs are connected through EasyPost's REST API or third-party middleware. Vendor-cited customers include Walmart, eBay, Dell, The Home Depot, and Warby Parker.
