Shopify

Shopify is the leading multi-channel commerce platform: it provides a complete, subscription-based solution for businesses to start, run, and scale their online and physical retail operations.

Shopify delivers a comprehensive commerce operating system: merchants launch and manage their entire business from one command center. The platform handles everything: online storefront creation, secure payment processing via Shopify Payments, inventory control, and multi-channel selling (web, mobile, social media, and brick-and-mortar with Shopify POS). Built on a robust tech stack, including Ruby on Rails and the Liquid templating language, the system scales to handle massive traffic, like the 80,000 requests per second seen during peak sales events. This unified approach empowers businesses—from SMBs to large enterprises using Shopify Plus—to unify their commerce and focus on growth.
