A Shopify Agency for San Francisco Teams
SDG is a San Francisco Shopify agency for enterprise brands that need more than a theme launch. Shopify’s original enterprise partner, a Shopify Platinum Partner, and a Build Award winner, we bring two decades of platform depth to Bay Area replatforms, custom development, and integrations.
A Shopify partner built for Bay Area technical teams
San Francisco commerce teams tend to arrive with strong opinions, mature engineering practices, and systems that cannot simply be replaced. That suits us. SDG works alongside product, engineering, ecommerce, and operations leaders to define the architecture, divide ownership clearly, and ship within the standards an internal team already uses.
The engagement can begin with a platform evaluation or technical audit, a focused feature, or a complete Shopify Plus replatform. In each case, senior practitioners stay close to the work from discovery through launch. There is no account layer translating technical decisions back and forth.
Enterprise Shopify migration without erasing what works
Bay Area brands often have valuable capabilities inside a custom platform, headless stack, or legacy commerce system. A good migration does not discard that investment indiscriminately. We identify what Shopify can simplify, what should remain a system of record, and what needs to be rebuilt because it creates real customer or operational value.
For Everlane, SDG led a move from a custom platform to Shopify Enterprise while preserving the editorial flexibility the brand needed. Our Shopify migration practice brings the same discipline to catalog data, integrations, redirects, analytics, performance, and cutover.
Liquid, headless, and architecture with a reason
We build high-performing Liquid storefronts, custom Shopify applications, and headless experiences with Hydrogen and Oxygen. The architecture follows the business case. Headless can be the right choice for complex content, multiple experiences, or a product organization that needs frontend autonomy; it should not be a reflex that leaves the commerce team with more infrastructure than value.
Our Shopify developers work through that decision with your team, including content ownership, deployment, observability, preview workflows, performance budgets, and the long-term cost of operating the stack.
Integrations designed around systems of record
Enterprise storefronts only work when the operational layer works. We connect Shopify to ERP, OMS, PIM, CRM, CMS, analytics, tax, payments, and fulfillment platforms with clear data ownership, retries, reconciliation, monitoring, and recovery paths.
Explore our Shopify integration practice, including NetSuite, Manhattan Active Omni (MAO), and headless CMS platforms. When a standard connector fits, we use it. When the business process is the differentiator, we engineer the custom layer carefully.
Local context, enterprise delivery
Our San Francisco presence makes workshops, architecture sessions, and critical launch windows easier for Bay Area teams, while the wider SDG team supports delivery across time zones. We work with brands in San Francisco, Oakland, Silicon Valley, and throughout Northern California, as well as distributed teams worldwide.
What remains consistent is the operating model: direct access to senior people, visible decisions, practical documentation, and a team accountable for the outcome after the presentation ends. See our enterprise Shopify case studies or bring us the problem that has outgrown the current platform.
