A Shopify Plus and Enterprise Agency for Consequential Work
SDG is a Shopify Platinum Partner, Shopify’s highest current service-partner tier, and a Build Award winner. We architect, migrate, build, and operate Shopify Plus and Enterprise for brands whose catalog, channels, systems, and traffic make the platform decision consequential.
Trusted by brands that define their categories
Make the platform, partner, and architecture decisions with evidence
Use these commercial services and decision resources to evaluate the move, define the investment, and resolve the highest-risk parts of an enterprise Shopify program.
When Shopify Plus is the right enterprise platform
Shopify Plus is a strong fit when a brand needs enterprise scale without owning an enterprise-sized commerce infrastructure: high-volume selling, multiple storefronts or markets, B2B, retail, sophisticated merchandising, extensible checkout and account experiences, and an ecosystem that lets the internal team move quickly.
The decision still needs evidence. We evaluate catalog shape, business models, international requirements, checkout logic, content operations, security, accessibility, team workflows, and every system behind the sale. Our Shopify consulting practice turns that evaluation into a defensible business case, total cost of ownership model, target architecture, and delivery roadmap.
Enterprise replatforming with every dependency visible
A Shopify Plus migration is a business transformation disguised as a website project. Catalog and customer data, order history, content, URLs, analytics, payments, tax, subscriptions, loyalty, ERP, OMS, PIM, fulfillment, service, and finance all need to work on the other side of the launch. We plan those workstreams together and rehearse the data and cutover before the live window.
SDG has migrated some of retail’s most demanding catalogs and operations, including Barnes & Noble and Everlane. See our enterprise Shopify migration practice and platform-specific guides for Salesforce Commerce Cloud (SFCC), Magento, Oracle ATG, AEM, and custom platforms.
Liquid, headless, or hybrid, chosen for operating fit
A well-engineered Liquid storefront gives many enterprise brands the best combination of speed, native capability, maintainability, and merchant control. Headless with Hydrogen and Oxygen earns its place when content, multiple experience surfaces, frontend autonomy, or a genuinely custom journey creates enough value to justify the added stack.
We model that tradeoff before implementation: performance, preview and publishing, hosting, observability, release ownership, application dependencies, and the team required to operate it. The result may be native, headless, or hybrid. It will have a reason.
One platform across DTC, B2B, markets, and retail
Shopify Plus can consolidate customer experiences that previously lived in separate platforms. We build DTC and Shopify B2B storefronts, company accounts and contract pricing, international programs with Shopify Markets, and unified retail with Shopify POS. Shared platform capabilities reduce duplicate work while preserving the workflows each channel actually needs.
Where native Shopify is not enough, we extend it with custom applications, Checkout Extensibility, customer account and POS UI extensions, Shopify Functions, Flow, and carefully selected ecosystem products.
The systems layer determines whether enterprise commerce holds
Enterprise operations depend on reliable ownership and movement of product, price, inventory, customer, order, payment, fulfillment, return, and financial data. We integrate Shopify Plus with ERP, OMS, PIM, CRM, CMS, WMS, tax, payments, loyalty, analytics, and custom middleware using observable flows with retries, reconciliation, and recovery.
Our Shopify integrations include NetSuite, SAP, Microsoft Dynamics, Manhattan Active Omni (MAO), IBM Sterling, Salesforce, Salsify, Akeneo, Sanity, Contentful, and more. The goal is not to force Shopify to own everything; it is to make every system’s responsibility clear.
Platinum status, senior accountability
SDG has worked with Shopify since 2006 and won a Shopify Build Award for Glossier. Shopify positions Platinum, its top current service-partner tier, for global enterprise businesses. The credential matters because it is independently verifiable; the working model matters because senior people scope the program, make the architectural decisions, and remain present through delivery and launch.
