Endicia

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.

Products and services

• Endicia Label Server Endicia Label Server is a web-based postage and shipping label service that lets users print USPS postage and shipping labels directly from a computer. It integrates with ecommerce platforms and shipping carriers for streamlined fulfillment, and is offered both as a standalone subscription and embedded within 600+ partner platforms via the Label Server Web Service API.
• DaZzle DaZzle is Endicia's desktop shipping software that provides streamlined package processing for Endicia users. It includes address verification through the Dial-A-ZIP server and is targeted at customers who print shipping labels from a Windows or Mac workstation and want tight integration with USPS postage.
• ShipStation API The ShipStation API is Auctane's shipping and logistics integration platform that enables developers to embed shipping capabilities, connect selling channels, automate tasks, find best rates, and manage shipments and returns from a single platform. It is positioned within the Auctane family as the integration layer shared by Endicia and sister brands.
• GlobalPost Service GlobalPost Service is Endicia's international shipping offering that enables customers to ship packages from the United States and from international posts at discounted rates through a network of third-party parcel processing facilities. It is governed by Section 11 of Endicia's Terms and Conditions and includes options such as SmartSaver Ship-In, SmartSaver Pickup, and SmartSaver Dropoff.

Endicia offers both personal virtual postage meters and aggregate virtual postage meters that manage account funds and the purchase of postage through the Endicia platform.
• Refund Assist Refund Assist is an automated add-on service that identifies eligible shipping labels for refunds, submits refund requests on behalf of users to the carrier, and updates the Endicia account balance upon receipt of processed refunds. It is priced separately from base service plans and billed per active billing cycle.
• Pay-on-Use Shipping Labels Pay-on-Use is a shipping label add-on for qualified Endicia customers that defers shipping charges until the label is scanned by the carrier in the mail stream, rather than billing at the time of print. It is governed by Section 13 of Endicia's Terms and Conditions and is intended for customers who want to reduce upfront postage spending.
• Warehouse Solutions Warehouse Solutions is Auctane's high-volume shipping offering that brings speed, automation, and simplicity to warehouse fulfillment, allowing operators to process thousands of orders across multiple selling channels.
