What Endicia does
Endicia, operating as PSI Systems, Inc. dba Endicia and headquartered under Texas jurisdiction, provides online postage, mailing, and shipping software for online sellers, warehouse shippers, and home and office mailers. Its core technology is a cloud-based mailing and shipping platform with USPS-authorized virtual postage meter capability (PC postage evidencing), supported by the Endicia Label Server web service for label generation, the DaZzle desktop software for streamlined package processing, and the proprietary Dial-A-ZIP address verification capability. Distribution is anchored on a network of 600+ integration partnerships across ecommerce platforms (Shopify, Amazon, eBay, BigCommerce, WooCommerce), ERP systems (SAP, Oracle, NetSuite, Microsoft Dynamics), WMS solutions, and marketplace connectors, with the Auctane ShipStation API providing developer-facing extensibility.
Revenue is generated through monthly service plan subscriptions, term/pre-paid service plans, subscription-free pay-as-you-go postage and shipping plans, transactional postage and shipping fees (including dimensional weight adjustments and insurance), add-on services such as Refund Assist and Pay-on-Use labels, and quoted professional services for onboarding and configuration. Customer segments are primarily small-to-mid-size businesses, multichannel e-commerce sellers managing orders across multiple sales channels, and high-volume warehouse shippers requiring batch fulfillment automation. Go-to-market combines direct online self-service registration and 1-800 phone sales with channel-driven acquisition through the partner network and developer integrations.
Endicia is now part of Auctane, a privately held strategic operating company whose portfolio also includes Stamps.com, ShipStation, ShipEngine, and GlobalPost. Within that portfolio, Endicia is the brand associated with USPS PC postage, SMB and warehouse-focused shipping software, and the broadest integration footprint, while Stamps.com handles office mailing and ShipStation handles multi-channel ecommerce logistics for sister segments. Operating status is active with an active website (endicia.com), customer service line (1-800-576-3279), and continued integration partner accumulation as of 2025.
