Custom Business Applications Connected to Shopify

Extend Shopify around the business, not around an app catalog

Shopify provides a powerful commerce core, but a distinctive operating model may cross systems and users no off-the-shelf application understands completely. A custom business application can coordinate those requirements without forcing the storefront, ERP, or merchant admin to own responsibilities that do not belong there.

We begin with the user and outcome, then define which Shopify capabilities, applications, custom services, and enterprise systems should participate. The goal is the smallest maintainable architecture that gives the business a real advantage.

Applications beyond the storefront

The same Shopify data and workflows that power commerce can support specialized applications for every team around it.

• Merchant workbenches for catalog enrichment, content readiness, assortment, pricing, promotions, launches, and market operations.
• B2B buyer portals, account onboarding, quoting, approvals, custom catalogs, reordering, service, and partner workflows.
• Order review, exception management, returns, exchanges, fulfillment coordination, inventory visibility, and customer-service tools.
• Product and content workflows connecting Shopify to PIM, DAM, CMS, translation, regulatory, and approval systems.
• Operational dashboards that combine commerce, inventory, margin, service, fulfillment, and marketing data with actions, not only charts.
• AI assistants and agents for merchants or customers, grounded in current Shopify data and limited to approved tools and actions.

Use Shopify as a platform without making it the only system

We work with Admin APIs, Storefront APIs, webhooks, Shopify Functions, Flow, app extensions, customer accounts, B2B primitives, Markets, and Shopify data models where they fit. We connect them to ERP, OMS, PIM, WMS, CRM, finance, identity, data warehouse, and specialized services through governed integration patterns.

Every flow defines the system of record, idempotency, validation, retries, reconciliation, rate limits, observability, and recovery. That discipline keeps a helpful application from becoming another hidden source of commerce truth.

Build for enterprise permissions and operational consequence

Merchant and operational tools can change prices, products, customers, orders, inventory, and money. We design identity, roles, resource permissions, approval paths, audit trails, and safe failure behavior around that consequence. AI-generated recommendations never become authorization by themselves.

The application receives the same production discipline as a customer-facing system: threat modeling, accessibility, automated testing, environments, controlled deployment, monitoring, performance, documentation, incident readiness, and support.

From prototype to a supported Shopify product

If your team already built a prototype, SDG can assess the repository and connected Shopify development store, identify risks, and preserve the proven workflow. If the application is new, we can lead product definition, UX, architecture, app and service development, systems integration, testing, launch, and ongoing operation.

This practice connects our enterprise AI application development, Shopify development, and enterprise integration teams in one accountable delivery model.
