What SixBit Software does
SixBit Software is a privately held, bootstrapped desktop software company headquartered in Sayre, Pennsylvania. Founded in 1997/1998, the company develops and sells SixBit, a Windows-based eCommerce management application that runs locally on customer machines using a bundled SQL Server Express database, enabling offline work and integration with marketplace APIs (eBay, Etsy, and beta support for HipCommerce collectibles marketplaces such as HipStamp, HipPostcard, and HipComic). The product bundles listing management, inventory tracking, order processing, consignment handling, reporting, drop shipping, fitments/compatibility management, promotions, purchase orders, label and packing slip printing, and a deep variable-driven description system.
The company targets primarily small businesses and individual professional sellers operating on eBay and Etsy, including vertical specialists in philatelics, automotive parts, collectibles, and consignment. Distribution is direct-to-customer via a self-serve 30-day free trial and downloadable installer from the company website. The company monetizes through annual subscriptions with tiered support plans (Bronze included with all subscriptions, Silver Priority at $399 per year, Gold Priority at $599 per year), and offers paid support upgrades, an affiliate program paying 10% of referred subscription fees, and partnerships with template designers and shipping/warehouse systems (UPS Worldship, Endicia, Barcoders, Monsoon StoneEdge).
SixBit holds a 2025 eBay Gold Badge as a verified compatible solution and positions itself on 27+ years of domain expertise, offline desktop reliability, and deep customization. The company has 11-50 employees, no disclosed external funding or institutional ownership, and ongoing product releases through v5.00.010 in 2026. Customer evidence consists of long-tail testimonials from individual and SMB sellers rather than named enterprise accounts.
