What is Shopify Plus?
Shopify Plus is an enterprise e-commerce platform from Shopify, designed for businesses with high demands in terms of growth, automation, internationalisation and system integration. The platform is suitable for B2B, B2C and D2C business models and can be connected via APIs to ERP, PIM, CRM, logistics and other systems.
As a Shopify Plus agency, Sitewerk supports businesses with strategy development, UX/UI design, technical implementation, system integration and the further development of sophisticated e-commerce solutions.
Benefits of Shopify Plus
High-performance SaaS infrastructure
Shopify Plus offers a stable e-commerce platform for businesses with high demands in terms of operations, performance and availability. Teams no longer need to manage their own shop infrastructure and can therefore focus more on development, conversion and the customer experience.
Rapid further development
With Shopify Plus, new sales channels, markets, features and campaigns can be implemented efficiently. Standardised platform functions, apps, APIs and automations reduce the technical maintenance workload and shorten development cycles.
Flexible scalability
Shopify Plus can be adapted to existing business processes using apps, APIs and bespoke developments. ERP, PIM, CRM, payment, logistics and marketing automation systems can be integrated, ensuring that product data, prices, orders and customer data are available across all systems.
Automation with Shopify Flow
Shopify Flow allows you to automate recurring tasks, such as those relating to orders, segmentation, internal notifications or operational workflows. This enables e-commerce teams to manage their processes more efficiently and reduce manual work.
Headless Commerce
Shopify Plus can be used as a commerce backend in a headless architecture. In this setup, the frontend is developed independently, whilst Shopify provides core commerce functions such as products, the shopping basket and checkout.
Shopify Plus for B2B commerce
Shopify Plus supports B2B commerce with features such as corporate accounts, customer-specific catalogues, customised price lists and multiple buyer roles. Combined with ERP, PIM and CRM integrations, even more complex B2B sales processes can be mapped digitally. Shopify Plus can provide a stable foundation for digital self-service processes, customer portals and international B2B shops for businesses with multiple customer groups, bespoke terms and conditions or recurring orders.
When does headless commerce with Shopify Plus make sense?
Shopify Plus can be used either with Shopify themes or with a bespoke front-end. This architecture is known as headless commerce. In this setup, Shopify Plus handles key commerce functions such as product data, the shopping basket, checkout and orders in the background. The visible user experience is designed and developed independently of this. Headless Commerce is a good option when businesses require highly customised user experiences, high performance or multiple digital touchpoints. These include, for example, websites, apps, customer portals, 3D visualisations, personalisation or international commerce set-ups.
For many e-commerce projects, however, the classic Shopify architecture with themes, apps and APIs is sufficient. Headless is particularly worthwhile when design, content, performance or system integrations need to be more highly customised.
Shopify Plus as a building block for composable commerce
Composable commerce means that an e-commerce platform is built using a modular approach. Rather than incorporating all functions into a single system, specialised solutions such as Shopify Plus, CMS, PIM, ERP, CRM or customer portals are interconnected via APIs. Within such an architecture, Shopify Plus can handle the commerce side of things, namely product management, the shopping basket, checkout and orders. Additional systems are integrated as required, for example for content, product data, customer data, logistics or self-service processes.
This approach is particularly well-suited to businesses that wish to continue using existing systems, integrate new features more quickly or expand their e-commerce platform in stages.
