ShipWorks
By ShipWorks
ShipWorks is a high‑performance, multi‑carrier shipping platform built for warehouses and high‑volume eCommerce merchants. It combines a Windows desktop application with cloud components (“The Hub”) to deliver fast label processing, extensive integrations, and white‑glove support. Today, ShipWorks operates as a subsidiary within Auctane (formerly Stamps.com), alongside sister brands such as ShipStation, ShipEngine, Endicia, Metapack, and Packlink.
ShipWorks positions itself explicitly for high‑volume, multi‑location shippers who need speed and deep workflow automation—publishing performance numbers like ~16,000 labels/hour, 99.99% uptime, and 70+ integrations across marketplaces, carts, ERPs, and WMS systems.
ShipWorks traces its roots to Interapptive, Inc., founded in 2000 by Wes Clayton and Brian Nottingham in St. Louis, Missouri. The brand grew by serving online sellers with a desktop‑installed shipping client that integrated early with marketplaces (eBay, Amazon, Yahoo) and carriers (UPS, FedEx, USPS).
The company maintained a St. Louis base for years while expanding features and integrations; after acquisition, it also developed a presence within Auctane’s Austin, Texas headquarters ecosystem, reflecting its integration into the broader shipping software portfolio.
ShipWorks was not venture‑funded in the typical sense; its major capital event is its acquisition by Stamps.com (now Auctane) for $22 million on October 20, 2014.
Public filings and databases corroborate the deal structure, listing Interapptive/ShipWorks as acquired by Stamps.com/Auctane, with ShipWorks subsequently consolidated into the parent’s financials.
At the parent level, Auctane (formerly Stamps.com) was later taken private by Thoma Bravo for $6.6 billion in July 2021, and rebranded to Auctane that December—context that frames ShipWorks’ current ownership but not an independent ShipWorks valuation post‑acquisition.
ShipWorks’ core product is a Windows‑installed shipping client with cloud dashboards for visibility and orchestration. It centralizes orders from 70+ channels, connects to carriers (UPS, FedEx, USPS, DHL, GlobalPost), and automates workflows via rules, templates, and barcode‑driven processes. Key capabilities include:
ShipWorks also publishes Quick Start and verification guides that walk teams through setup, carrier defaults, cut‑off times, label formats, and printing configurations, reflecting the platform’s emphasis on operational detail.
As noted, ShipWorks itself was acquired by Stamps.com/Auctane in 2014 (for $22M), entering a portfolio that also includes ShipStation (acquired the same year) and Endicia (2015). This consolidation strategy gave ShipWorks access to broader carrier relationships, product cross‑pollination, and shared infrastructure under the Auctane umbrella.
Auctane later rebranded from Stamps.com and refreshed leadership to accelerate growth across overlapping solutions, signaling continued investment in shipping technology across the portfolio—including ShipWorks’ high‑volume niche.
Recent feature evolution emphasizes security, customization, and developer extensibility:
ShipWorks brands itself around white‑glove, U.S.-based customer support with unlimited phone/email assistance, highlighting expert, non–script‑reader agents. The company’s “Support” materials emphasize problem‑solving, remote assistance, and long‑term relationships—values consistent with servicing mission‑critical warehouse operations.
Its “About/Company Info” messaging underscores a two‑decade focus on shipping performance, automation, and letting customers “focus on growth” while ShipWorks “just works,” reflecting a culture that prizes reliability and operational excellence over flashy features.
ShipWorks targets high‑volume merchants and multi‑warehouse operations—explicitly steering smaller shippers (<5,000 monthly shipments) toward sister product ShipStation, while positioning ShipWorks for >5,000 and multi‑location setups.
ShipWorks also maintains an active support portal and community, providing quick start guides, documentation, and troubleshooting content—resources that help customers self‑serve and share best practices.
