Our Shopify Plus
Development Process

A successful Shopify Plus Development project requires more than writing code. We combine strategic planning, thoughtful architecture, Custom Shopify Development, and rigorous testing to create scalable commerce experiences.

Discovery, Scope & Planning

We begin by understanding your business, customers, existing technology, and growth objectives. This gives us a clear foundation for building the right Shopify Plus architecture and development roadmap.

  • Requirements Gathering: Identify business goals, customer needs, technical requirements, and essential commerce features.

  • Technical Audit: Review your existing Shopify setup, theme, apps, integrations, performance, and technical architecture.

  • Development Roadmap: Define architecture, priorities, integrations, milestones, and technical requirements for a successful build.

Architecture & Development

We translate the approved UX and designs into a flexible Shopify Plus architecture. Our developers focus on creating scalable, maintainable systems that support both current needs and future growth.

  • Custom Shopify Development: Build tailored storefronts, sections, templates, features, and functionality based around your business requirements.

  • Theme & Custom Development: Develop scalable Shopify Custom Theme components and commerce systems designed to grow with your store.

  • Performance & Scalability: Build with speed, stability, scalability, and flexibility in mind to deliver a fast experience across your storefront.

Integrations & Advanced Commerce

Modern commerce rarely operates in isolation. We connect Shopify Plus with the systems your business relies on, creating a seamless ecosystem across technology and operations.

  • Third-Party Integrations: Connect ERP, CRM, PIM, OMS, subscriptions, reviews, search, payments, and other essential platforms.

  • Custom Shopify Apps: Develop custom applications and functionality when existing apps cannot meet your business requirements.

  • Shopify ERP Integration: Implement connected pricing, inventory, customer experiences, subscriptions, promotions, and other enterprise commerce requirements.

QA, Launch & Continuous Improvement

Before launch, we put every part of the experience through rigorous testing. After launch, we continue monitoring and optimizing the platform to unlock performance as your business grows.

  • Quality Assurance: Test functionality, responsive layouts, browsers, devices, integrations, checkout flows, and edge cases.

  • Launch & Migration: Handle deployment, data migration, redirects, analytics, tracking, and launch coordination with minimal disruption.

  • Ongoing Optimization: Monitor performance, identify opportunities, resolve issues, and continuously improve the Shopify Plus experience.

Is this the right fit ?

Our Shopify Plus Development service isn't for everyone. Here's who it's built for.

Who it's for

  • Brands that need custom Shopify Development built properly around their business requirements and customer experience.
  • Brands with performance issues that need a faster, more scalable Shopify experience.
  • Shopify Plus brands looking to unlock advanced functionality, integrations, and scalable development.
  • Brands that want an experienced development team without building a full in-house team.
  • Brands that value conversion-focused development over cheap development hours.

Who it's not for

  • Brands looking for the cheapest Shopify developer or lowest hourly rate. We compete on value, not price.
  • Brands looking for development without strategic input or consideration for long-term growth.
  • Brands that only need a basic Shopify store with no custom functionality or technical requirements.
  • Brands looking for a one-off developer without ongoing support, communication, or accountability.
  • Brands looking for development without considering UX, performance, scalability, or conversion.

If the fit's right, the call's easy. If it's not, we'll tell you honestly and point you toward a better option.

Our Partner StoriesThat Inspire Bigfolio

We partner with ambitious Shopify Plus brands that want to build better. From custom Shopify Development to complex commerce experiences, we meet brands where they are and help them move forward with confidence.

Bigfolio has been an outstanding technology partner for Fandiem. They led our migration to Hydrogen and built the custom platform behind our charity campaigns, auctions, fundraising operations, and complex commerce workflows.

What sets Bigfolio apart is their ability to understand complex business requirements and turn them into fast, scalable, well-engineered solutions. Their technical expertise, problem-solving, communication, and attention to detail have been exceptional throughout our partnership.

I highly recommend Bigfolio to any company looking for a trusted Shopify Plus and custom commerce partner.
