Shopify is the optimal platform for running your own e-commerce site.

Shopify's open API and platform policies enable robust integration with external services. Shopify has pioneered many world-first integrations — including the first Instagram Shopping integration and Amazon Pay built into the admin panel. Third-party integrations and Apps that extend Shopify's capabilities are abundant. For example, Criteo, Treasure Data, and advanced personalization tools like Nosto are pre-integrated, so you can start using them without custom development.

Domestically, many payment providers such as NP後払い and atone, as well as logistics and marketing tools, are also integrated.

Shopify comes standard with REST API, GraphQL, and webhooks for data handling, enabling integration with external systems. Among various systems, Shopify Plus is typically the most agile hub, often serving as the central data layer. Common systems we integrate include WMS (client warehouse systems), ERP (SAP, NetSuite), and DWH/MA tools (Salesforce Marketing Cloud, b→dash) — through mutual API integration or CSV file exchange via SFTP.

Shopify offers an official POS system (Shopify POS). Combined with Shopify's e-commerce capabilities, a complete omnichannel solution is achievable. Even without Shopify POS, you can sync loyalty points across offline and online channels, display in-store inventory on the e-commerce site, reference e-commerce inventory in stores, and add click-and-collect options at checkout — enabling comprehensive customer integration.

Freedom from infrastructure concerns is a hallmark of Shopify. Unlike WordPress, there's no need to manage version updates or servers — resources can focus on growth. With infrastructure capable of handling 10,000 purchases per minute (powered by Google Cloud), auto-scaling is fully automatic (no configuration needed), and servers never crash under load or oversell inventory.

Developer experience is often overlooked when selecting a platform. UX, operational usability, and the degree of automation are critically important, but once winning UX patterns are identified and operations stabilize, what becomes crucial for growing the e-commerce system is how easily developers can work with it.

This isn't solely a system issue, so Shopify Plus doesn't solve every problem, but at minimum, when engineers are ready to take action, Shopify offers an extremely developer-friendly architecture compared to other platforms. Thanks to Shopify's API-centric design, technical debt accumulates far more slowly — a significant long-term advantage.
