Custom Theme Development Company in India

Shopify 2.0 (launched 2021) introduced a new theme architecture with several major improvements over Shopify 1.0. The most significant change is that Shopify 2.0 allows JSON templates - meaning merchants can add, remove, and reorder sections on any page (product pages, collection pages, blog posts), not just the home page. Shopify 2.0 also introduced metafields as first-class theme data (replacing third-party apps for structured content), app blocks allowing app integrations within the Theme Customizer, and improved performance APIs. All new Shopify themes built in 2025 and beyond should use Shopify 2.0 architecture. Legacy Shopify 1.0 themes should be migrated to Shopify 2.0 for the flexibility and performance improvements.

A Shopify theme customization (modifying existing sections and styles) takes 2-4 weeks. A semi-custom Shopify theme with custom sections and design takes 4-8 weeks. A fully custom Shopify theme from scratch takes 6-12 weeks. A custom WordPress theme takes 4-10 weeks. A headless Next.js storefront theme takes 8-16 weeks. A complete enterprise design system takes 6-16 weeks. Timeline depends on design complexity, number of page templates, animation complexity, the number of review and revision cycles, and whether designs are provided upfront or created as part of the project.

A design system is a centralized collection of reusable components, design tokens (colour, typography, spacing, shadow), usage guidelines, and documentation that ensures visual and functional consistency across all digital products. Design tokens are the foundation - a semantic colour name like --color-brand-primary maps to your exact brand colour hex value, and that mapping propagates to every button, every heading, and every highlight across your website, app, and email templates. You need a design system when: multiple teams (web, mobile, email) need to maintain consistent brand experience, you have multiple products with shared visual language, or your current digital estate has inconsistent fonts, colours, and components because each was built independently.

Figma-to-code implementation is the process of converting a Figma design file into production-ready code - HTML/CSS/JavaScript for web, Liquid for Shopify, PHP for WordPress, or React for headless. The goal is pixel-perfect accuracy: every spacing value, font weight, shadow, border radius, colour, hover state, animation timing, and responsive breakpoint in the Figma design is matched precisely in the code. A good Figma-to-code implementation also catches design issues before they become code - insufficient colour contrast, missing interactive states (hover, focus, disabled, loading, error), and responsive layout decisions that need clarification. Evolution Infosystem reviews Figma designs before coding begins to resolve these issues when they are cheap to fix.

Custom themes directly impact SEO in several measurable ways. Performance: custom themes load faster than template themes bloated with unused CSS and JavaScript - and Google's Core Web Vitals (LCP, INP, CLS) are direct ranking signals since the 2021 Page Experience Update. Semantic HTML structure: custom themes use proper HTML5 semantic elements (header, nav, main, article, aside, footer) rather than generic div-heavy template markup, which Google uses to understand page structure. Schema markup: custom themes can integrate product, breadcrumb, and organization schema cleanly without conflicting with plugin-generated schema. Mobile optimization: custom themes are built mobile-first rather than desktop-first scaled down, resulting in better mobile Core Web Vitals scores.

Yes. We regularly inherit existing Shopify or WordPress themes for optimization or extension. Our process starts with a theme audit: performance analysis (Lighthouse scores, bundle size analysis, image audit), code quality review (CSS specificity issues, JavaScript errors, deprecated APIs), accessibility audit, and extension complexity assessment. We provide a written audit report with findings and recommendations before any changes are made. Common theme improvement projects include: performance optimization (targeting 90+ Lighthouse), accessibility remediation (WCAG 2.1 AA compliance), new section or component development following existing patterns, responsive design fixes for mobile breakpoints, and migration from Shopify 1.0 to Shopify 2.0 architecture.
