FOLSOM, Calif. - eTradeWire -- Salloq Software, an enterprise software firm founded in 1993, today announced the launch of CartOS, a comprehensive e-commerce platform that gives online merchants full ownership of their storefronts, a modular extension architecture, and transparent pricing with no hidden fees.

CartOS is a full-stack commerce solution encompassing hosted storefronts, point-of-sale systems, built-in marketing automation through Cascade, and a developer ecosystem. The platform uses Liquid-based templating, making it immediately familiar to experienced e-commerce developers, and supports everything from first-time sellers to high-volume DTC brands with international, B2B, and multi-store needs.

MODULAR BY DESIGN:
Central to CartOS is its Bolt extension system — modular add-ons that inject functionality into any storefront without modifying theme code. The platform ships with core bolts for Reviews, Shipping Protection, Product Bundling, Email Marketing, SEO, and Split Testing. Third-party developers can build and distribute their own bolts through the Bolt Store.
