The short answer
What does a Shopify development agency do?
Shopify development is the practice of building, customising and scaling ecommerce stores on the Shopify platform: including custom theme development, Shopify Plus implementation, GemPages and PageFly page building, app development, Liquid template work and headless storefronts using Hydrogen.
Shopify handles hosting, security and checkout, which is why it suits most growing brands. What it does not do is make your store fast, distinctive or easy to run. That comes from how the theme is built, how many apps are loaded on every page, how product data is structured and how the store connects to your fulfilment and marketing tools. That is the work an agency is for.
SpiderHunts Technologies is a UK-registered agency with its registered office in London and the whole team in Lahore, working with Shopify clients across the UK, USA, UAE, Canada, Europe and Australia. We build Shopify stores designed to convert: fast Core Web Vitals, clean product pages, optimised checkout and integrated analytics from day one.

03
GemPages & PageFly design
High-converting landing pages, product pages and collection pages designed in GemPages, PageFly, Shogun or Replo. Designed for conversion, not just visual polish.
04

06
CRO, speed & SEO
Shopify speed optimisation, checkout optimisation, technical SEO, schema markup, A/B testing setup and analytics integration. The work designed to turn traffic into revenue.
07
Migrations to Shopify
From WooCommerce, BigCommerce or Magento: product, customer and order migration, SEO redirects to help preserve rankings, design migration, app re-platforming and post-migration QA.
08
B2B, wholesale & international
Trade pricing and wholesale catalogues, multi-store and organisation-level Plus configuration, and multi-currency, multi-language storefronts for selling across borders.
09
Store audits & ongoing support
A review of theme code, app load, speed, tracking and checkout, with prioritised fixes: then a retainer for theme updates, new sections and campaign pages if you want one.
Where Shopify stores go wrong
Shopify is easy to launch on. It is just as easy to slow down.
Most Shopify stores we are asked to fix were not built badly on day one. They drifted: one app, one snippet, one quick theme edit at a time.
A store that has drifted
- Twenty-plus apps, each injecting scripts, and a mobile page that takes seconds to become usable
- Theme files edited directly, so the next theme update cannot be applied safely
- Landing pages built by hand in the theme, so marketing waits on a developer for every campaign
- Product data inconsistent across variants, breaking filters, feeds and search
- Stock and orders re-keyed into the ERP, 3PL or accounting system
A store rebuilt by SpiderHunts
- Only apps that earn their place; simple features built into the theme instead
- A clean section and block architecture your team can extend safely
- GemPages or PageFly templates marketing can launch campaigns from on their own
- Structured product data that feeds filters, Merchant Center and marketplaces
- Orders, stock and customers synced with your other systems automatically
Is your store slow, bloated or hard to change?
Send us the URL. We will tell you what is slowing it down, which apps you could drop and whether it needs a rebuild or just a clean-up.
Typical projects
What Shopify projects usually look like
Most briefs we receive are one of these. The timelines are the ranges we quote for each.
Launch on Shopify properly
A custom or heavily customised theme, conversion-focused product pages, payments, shipping, tax, Klaviyo and analytics set up before the first order.
Custom store · 4–8 weeks
A landing page for paid traffic
A product or offer page in GemPages or PageFly, built for one audience and one action, with tracking that tells you whether the ad spend worked.
GemPages build · 1–2 weeks
WooCommerce or Magento to Shopify
Catalogue, customers and order history moved across, apps replaced with Shopify equivalents, and every ranking URL redirected before the switch.
Migration · 4–10 weeks
Shopify Plus implementation
Checkout extensions, Functions for discounts and shipping rules, Flow automations, Launchpad for sale events, and B2B or multi-store set-up.
Shopify Plus · 8–16 weeks
Headless storefront on Hydrogen
A fully custom front end on Hydrogen and Oxygen, or Next.js with the Storefront API, while Shopify keeps running products, checkout and orders.
Headless · 8–16 weeks
A custom app for a missing workflow
A private app on the Admin API connecting Shopify to your ERP, 3PL or loyalty platform, where no public app does what you need.
Scoped per app after discovery
How we work
How a Shopify project runs, step by step
You review real pages on a development store throughout, and nothing is published to your live theme until you have approved it.
Store review & discovery
We look at your current store or plans, apps, integrations, catalogue and goals, and agree what success means: conversion rate, speed, launch date or all three.
Free · 30-minute callScope & written quote
Templates, sections, apps to keep or replace, integrations and data to migrate, all written down with exclusions in a written quote.
3–5 daysDesign
Mobile-first designs for the templates that matter most, home, collection, product, cart, reviewed with you before development starts.
1–3 weeksBuild on a development theme
Liquid sections and blocks, page builder templates, apps and integrations built on an unpublished theme, with weekly demos you can click through.
2–10 weeksQA, launch & optimise
Test orders on every payment method and device, redirects and tracking checked, the theme published, then, on an optional retainer, speed and conversion work on real traffic.
Launch, then optional retainer
Clear scope · Regular demos · Full handover
Before you spend anything
When to hire a Shopify developer: and when not to
Shopify is designed so many merchants never need a developer. We would rather tell you that than sell you a build.
Hire one when…
- Your theme cannot do what your product pages need without hacks
- The store is slow and you suspect apps and scripts are the cause
- You are moving from WooCommerce, BigCommerce or Magento and need rankings preserved
- You need Shopify Plus features, B2B pricing or a headless front end
- Orders, stock or customers need to sync with systems outside Shopify
You probably don’t need one when…
- You are testing an idea: a free or premium theme configured well is enough
- The change is content, images or copy you can edit in the theme editor
- A well-reviewed app already does it for a modest monthly fee
- Sales are low because of traffic or product fit, not the store
- You want headless without a reason a theme cannot meet
Choosing the right build
Premium theme vs custom theme vs headless Shopify
All three are legitimate. The right one depends on how different your store needs to be and how much you want to own.
| Premium theme, customised | Custom Liquid theme | Headless (Hydrogen / Next.js) | |
|---|---|---|---|
| Best for | New stores and tight budgets | Established brands with specific page needs | Design-led or multi-brand stores with engineering support |
| Design freedom | Within the theme’s sections | High, built around your products | Unlimited |
| Speed potential | Good if apps are kept in check | Very good: only the code you need | Excellent, with more work to get there |
| Marketing team edits | Theme editor | Theme editor with your own sections | Needs a CMS set up for it |
| Typical timeline | 2–4 weeks | 4–8 weeks | 8–16 weeks |
| Ongoing ownership | Theme vendor updates | Your code, maintained by you or us | A separate application to host and maintain |

FAQ
Questions about Shopify development
Straight answers to what buyers ask before they sign.
Still have a question?
Ask us directly. A senior engineer reads every question.
Ask about your projectWhat is Shopify development?
Shopify development is the practice of building, customising and scaling ecommerce stores on the Shopify platform: including custom theme development, Shopify Plus, GemPages and PageFly page building, app development, Liquid template work, and headless Shopify storefronts with Hydrogen.
How much does Shopify development cost?
As a guide, a GemPages or PageFly landing page costs £1,000–£3,000, a custom Shopify store £5,000–£15,000, a migration to Shopify £5,000–£20,000, and Shopify Plus or headless builds from around £20,000. Your Shopify plan and apps are paid separately. We give a written quote, with scope and exclusions, after a free discovery call.
Do you build custom Shopify themes from scratch?
Yes. We build custom Shopify themes in Liquid with mobile-first design, accessibility built in, Core Web Vitals optimisation, and clean section and block architecture your marketing team can extend safely.
Do you work with GemPages, PageFly, Shogun or Replo?
Yes: all four. We design and build high-converting landing pages, product pages and collection pages in GemPages, PageFly, Shogun and Replo. We pick the right tool per project; the goal is conversion, not picking a favourite app.
Can you migrate from WooCommerce, BigCommerce or Magento to Shopify?
Yes. We handle product, customer and order migration; SEO redirects to help preserve rankings; design migration; app re-platforming; and post-migration QA. Most migrations run 4 to 10 weeks depending on catalogue size.
Do you build Shopify Plus stores?
Yes. We are familiar with Shopify Plus features including Launchpad, Flow, Functions, custom checkout extensions, B2B and wholesale, multi-store set-ups and organisation-level configuration. Where a store still relies on legacy Shopify Scripts, we rebuild that logic with Functions.
Do you build headless Shopify with Hydrogen?
Yes. We build headless Shopify storefronts using Hydrogen and Oxygen for brands that need full design freedom and strong performance. We also build headless using Next.js with the Shopify Storefront API where it fits better. For most stores, though, a well-built Liquid theme is faster to launch and cheaper to own, and we will tell you if that is the case.
How long does a custom Shopify build take?
A standard custom Shopify store typically takes 4 to 8 weeks. Shopify Plus implementations and headless builds typically run 8 to 16 weeks. GemPages page builds for single landing pages or campaigns typically run 1 to 2 weeks.
Can you build a custom Shopify app?
Yes. We build private and custom apps on the Storefront API and Admin API: typically to connect Shopify with an ERP, 3PL, subscription, loyalty or review platform, or to add a workflow no public app covers. Apps are scoped and quoted separately after discovery.
Why is my Shopify store slow, and can you fix it?
The usual causes are too many apps loading scripts on every page, oversized images, heavy page builder sections and leftover code from apps that were uninstalled. We audit the theme and app load, remove what is not earning its place, and rebuild slow sections, aiming to improve Core Web Vitals without losing features you rely on.
Will you edit our live theme directly?
No. We work on a duplicate, unpublished theme or a development store, review changes with you there, and publish only when you approve. That way your live store can keep trading while we work.
Where are you located and which markets do you serve?
SpiderHunts Technologies is a UK-based agency, registered in London with engineers in Lahore, serving Shopify clients across the USA, UK, UAE, Canada, Europe and Australia. We work fully remotely with time-zone overlap for each region.
