Why Sigill

What Makes Us a Different Shopify Agency

Most Shopify agencies install a theme and call it done. Here's what we do differently.

No Templates — All Custom

Every store we build is designed and coded from scratch in Liquid. You get a theme that's uniquely yours, not something 10,000 other stores are using. Our builds average 90+ on Google PageSpeed because there's zero unnecessary code.

Conversion-First Design

We don't just make stores look good — we design them to sell. Every layout decision is backed by ecommerce data: product page hierarchy, trust signal placement, cart abandonment reduction, and mobile checkout optimisation.

Fixed Price, Fixed Timeline

We scope every project in detail before we start. You get a written proposal with the full feature list, timeline, and fixed price — no hourly billing surprises. If scope doesn't change, price doesn't change.

Post-Launch Support

All Shopify builds include 30 days of free post-launch support. We monitor store performance, fix any bugs, and help your team get comfortable managing products and orders before handing the keys over.

Our Services

Full-Stack Shopify Development Services

Everything you need to launch, grow, and scale your Shopify store — under one roof.

01

Custom Shopify Theme Development

We build bespoke Liquid themes from scratch — fully responsive, accessible, and optimised for Core Web Vitals. Every section is built as a Shopify Theme OS 2.0 block so your team can manage content without a developer. We avoid page builders entirely: no Shogun, no PageFly, no bloat.

02

Shopify Plus Development

Enterprise Shopify builds with custom checkout extensions (Checkout UI Extensions + Shopify Functions), B2B/wholesale portals, multi-store setups with a shared theme, and Shopify Flow automations. We're experienced with Shopify Plus's expanded API rate limits and Markets Pro. See our dedicated Shopify Plus page for more.

03

Shopify App Integration

We integrate and configure the full Shopify tech stack — Klaviyo for email, Recharge for subscriptions, Yotpo or Judge.me for reviews, Gorgias for support, ShipBob or ShipStation for fulfilment, and any custom middleware. Every integration is tested end-to-end including edge cases.

04

Store Migration to Shopify

We migrate stores from WooCommerce, Magento, BigCommerce, Wix, Squarespace, OpenCart, and custom platforms. All products, variants, images, collections, customers, historical orders, metafields, and SEO URLs are preserved — with 301 redirects in place on day one. Zero data loss, minimal downtime.

05

Shopify Speed Optimisation

Slow Shopify stores lose customers — 1 second of load delay costs around 7% in conversions. We audit your theme's JavaScript bundle, lazy-load images and third-party scripts, consolidate redundant app code, and implement critical CSS. We regularly take stores from 40–55 PageSpeed to 85–95.

06

Custom Shopify App Development

We build private Shopify apps (internal tools, custom admin panels), public Shopify apps (for the App Store), and Shopify Functions (custom discounts, payment/delivery customisations). Our apps are built with Remix and the latest Shopify API version.

Our Process

How We Build Your Shopify Store

A structured process that eliminates surprises and gets your store live on time, every time.

01

Discovery & Scoping

We start with a 30-minute discovery call to understand your products, audience, competitors, and technical requirements. Within 24 hours you receive a detailed project proposal: full feature list, wireframe sketch, timeline by phase, and a fixed price. No vague estimates.

02

UI/UX Design in Figma

Before writing a single line of Liquid, we design every key page in Figma — homepage, collection, PDP, cart, checkout, mobile views. You review and approve each screen. This stage catches 90% of design changes before they're expensive to fix.

03

Theme Development

Custom Liquid theme built on Shopify's OS 2.0 architecture. Every section is drag-and-drop from the admin. We code mobile-first, write semantic HTML for accessibility, and optimise images via Shopify CDN. Code reviews are part of the process — no cowboy commits.

04

App Integrations & QA

All agreed integrations are installed, configured, and tested — Klaviyo flows, review widgets, loyalty apps, shipping rules. QA covers every checkout scenario, discount combination, and edge case across Chrome, Safari, Firefox, iOS and Android.

05

Launch & Handover

DNS cutover, 301 redirects verified in Screaming Frog, Google Search Console connected, sitemap submitted. You get a recorded Loom walkthrough of the admin, a written SOP for your team, and 30 days of free post-launch support.

What Our Shopify Clients Say

"Sigill rebuilt our entire Shopify store from scratch in 5 weeks. The new theme is lightning fast and our conversion rate went from 1.8% to 3.2% within the first month. Worth every rupee."

Sneha Kapoor
Founder, LuxeWear India

"We migrated from a Magento 2 store with 12,000 SKUs. Zero data loss, zero downtime, and they preserved every SEO ranking we had. The Shopify store is night and day — our team can actually manage it now."

V
Vikram Desai
Head of Ecommerce, FabHome

"Best Shopify developers we've worked with. They understood our subscription model, integrated Recharge seamlessly, and built a custom loyalty section in Liquid that no app could have done. Highly recommend."

Frequently Asked Questions

Everything you need to know about our Shopify development services.

A custom Shopify store with a fully bespoke Liquid theme typically costs ₹80,000–₹2,50,000 depending on complexity — number of pages, custom sections, and app integrations required. Shopify Plus builds or stores with custom app development start from ₹3,00,000. We always provide a fixed-price quote after a discovery call, so there are no surprises.

A standard DTC store (custom theme, 5–10 section types, basic app integrations) takes 3–4 weeks from design sign-off to launch. Complex stores with custom checkout extensions, B2B wholesale portals, or multi-store setups take 6–10 weeks. We publish a milestone-based timeline in every proposal so you know exactly what happens when.

Both. If budget allows, we strongly recommend building a custom Liquid theme from scratch — it gives you the best performance, unique design, and no dependency on a third-party theme vendor. If your budget is tighter, we can take a premium base theme (Dawn, Impulse, or Prestige) and customise it heavily — replacing sections, restructuring layouts, and extending functionality — so it looks nothing like the original.

Yes — migration is one of our core services. We handle the full migration: products (with all variants and images), collections, customers, historical orders, blog posts, and page content. We set up 301 redirects for every changed URL and verify them before launch. Your Google rankings are protected. See our Store Migration page for more detail.

Shopify Plus is the enterprise tier — it unlocks custom checkout (via Checkout UI Extensions and Shopify Functions), B2B/wholesale pricing, unlimited staff accounts, higher API rate limits, and Shopify Flow automations. It costs $2,300/month (or revenue-based pricing). For most DTC brands under ₹10Cr/year in revenue, standard Shopify is sufficient. We can advise which tier makes sense for your business.

All projects include 30 days of free post-launch support for bug fixes. After that, we offer monthly maintenance retainers starting at ₹15,000/month — covering updates, new feature requests, app additions, and performance monitoring. Many of our clients have been on retainer for 2–3+ years.

Yes. We've built custom middleware integrations connecting Shopify with Tally, SAP, Zoho CRM, Salesforce, and proprietary warehouse management systems — using Shopify's REST and GraphQL APIs combined with webhooks. These integrations sync inventory, orders, customer data, and fulfilment status in real time.

A well-built Shopify store is inherently SEO-friendly — clean URLs, fast load times, structured data, and sitemap.xml out of the box. We follow SEO best practices in every build: semantic HTML, proper heading hierarchy, optimised meta tags, canonical URLs, and schema markup. We also set up Search Console and submit your sitemap at launch.

Yes. Shopify Markets lets you sell in multiple currencies and languages from a single store. We configure currency conversion, market-specific pricing, translated content, and localised checkout. For truly independent storefronts per region, Shopify Markets Pro or a multi-store Shopify Plus setup is the right approach — we handle both.

It depends on your business model, but a typical DTC store needs: Klaviyo (email/SMS marketing), Judge.me or Yotpo (reviews), Recharge (if subscriptions), Gorgias (support), ShipStation or Shiprocket (fulfilment), and a loyalty app like Smile.io or LoyaltyLion. We help you pick the right apps for your use case and configure them properly — many store owners overpay for apps they don't fully use.
