Overview
Services for Shopify stores
Shopify development is the core of the MerchantBase practice. We are Shopify specialists rather than a general web agency: every build is shaped by how Shopify actually works — themes, Liquid, checkout, apps, the Admin API, and the operational systems behind the store.
That covers Shopify 2.0 theme development and custom Liquid, custom Shopify features and functionality, app and API integrations, Shopify Plus work, and performance optimization. The focus is clear implementation rather than overbuilt solutions — define the right scope, build carefully, test the important paths, and leave the team with documentation that explains what changed.
Supporting capabilities live inside this pillar rather than as separate service lines: migrations and launches (WooCommerce, Magento, BigCommerce, and custom platforms), B2B and wholesale requirements such as portals, tiered pricing, approvals, and quick order forms, and custom automation and internal tooling for operations teams.

Process
How the work usually runs
Scope the development work
We clarify the feature, workflow, or improvement before code starts. This includes understanding the business goal, affected pages, app dependencies, customer paths, and any constraints in the current Shopify setup.
Build and test
We implement the work in Shopify using the appropriate theme, app, checkout, or integration approach. Key customer paths are tested so the work supports the store rather than creating new friction.
Launch and document
After review, the work is launched carefully and documented where useful. Your team gets context on what changed, how to manage it, and what to watch for later.
FAQ
Common questions
Do you only work on Shopify?
Yes. Shopify is the platform we build on, so the recommendations are specific to how Shopify actually behaves. Migrations into Shopify from WooCommerce, Magento, BigCommerce, and custom platforms are part of this work.
Do you work with existing Shopify themes?
Yes. MerchantBase can improve existing Shopify themes, build custom sections, adjust templates, clean up front-end code, and support theme updates.
Can you help with Shopify Plus checkout extensibility?
Yes. We can help plan and implement checkout extensibility updates, including replacing older checkout customizations with supported Shopify approaches.
Do you take on small Shopify development tasks?
Yes. Focused Shopify development tasks are a good fit when the goal is clear and the work can be handled cleanly without a large project structure.
Do you build headless storefronts or Hydrogen?
We support teams exploring headless with honest scoping — most stores are better served by a strong Shopify theme, but we can plan and build a custom front-end when the business case is there.
