United Kingdom — Shopify App Developer

Built for UK, delivered senior-only

When no app in the store does exactly what your store needs — a custom integration, a merchant-facing tool, a public app for other merchants — a bespoke Shopify app is the answer. I build Shopify apps on the Admin and Storefront APIs with proper auth, webhooks, billing and review-readiness, so the app survives Shopify's review, real merchant volume, and API version changes.

Selling in the UK means VAT at the 20% standard rate, UK GDPR and PECR consent rules, and shoppers who expect Klarna and Clearpay alongside cards, Apple Pay and PayPal. Delivery expectations are set by Royal Mail, DPD and Evri, with next-day delivery common and returns handled as a normal part of the purchase, not an exception. Consumer Rights Act protections shape refund and product-information pages, and GBP pricing with clear delivery and returns terms is what British buyers check before they commit. I am Omer Muneer Qazi, with 15+ years of experience and 100+ projects delivered. UK business hours — GMT in winter, BST (UTC+1) in summer. Dubai is 3–4 hours ahead, so UK mornings overlap Dubai late morning and the full UK afternoon is covered for calls, reviews and launches. Let’s talk UK hours.

What you get

What a UK shopify app developer engagement covers

  • Custom apps for one store — private or custom apps that solve your store's specific workflow, integrated with your theme, ERP or fulfilment tools.
  • Public apps for the App Store — listing-ready apps with onboarding, billing, support docs and the polish Shopify's review process actually checks.
  • API and webhook engineering — Admin, Storefront and GraphQL APIs with webhook handling, retries and idempotency, so no order or event is silently lost.
  • Embedded admin experience — Polaris-based embedded apps that feel like part of Shopify, not a bolted-on external dashboard.
  • Version and billing discipline — API version upgrades planned, usage billing or subscriptions implemented cleanly, and merchant data handled per Shopify's rules.
  • United Kingdom specifics — UK checkout and compliance — VAT configuration, UK GDPR consent, Klarna and Clearpay placement, and Royal Mail, DPD and Evri delivery options set up for British shoppers.
How it works

From kickoff to UK launch

  1. App definition

    The problem, the merchant workflow, the data it touches and the billing model agreed, with Shopify's rules checked up front.

  2. Build in slices

    Auth and core workflow first, then admin UI, webhooks and billing, each slice reviewable on a development store.

  3. Review preparation

    For public apps: listing, screenshots, support docs and test flows prepared for Shopify's review before submission.

  4. Launch and maintenance

    Staged rollout, monitoring, version-upgrade plan and support, so the app keeps working as Shopify evolves.

FAQ

Questions, answered

Custom app or existing app?
If an existing app does 90% of the job, buy it. A custom app earns its cost only where the workflow is genuinely specific or the public app's fees exceed the build cost over time.
How long does Shopify review take?
It varies, and resubmissions are common. Review preparation is built into the schedule so a rejection is a fix, not a surprise.
Who owns the app?
You do — code, listing and merchant relationships, in your accounts. No dependency on me for routine operation.
What happens when Shopify changes its APIs?
Version upgrades are part of maintenance. Deprecated calls are tracked and migrated on Shopify's schedule, not after a breakage.
How do UK working hours and payments work?
Calls, reviews and launches run in UK business hours, with GMT in winter and BST in summer. Payments cover cards, Apple Pay, PayPal, Klarna and Clearpay, and tax and delivery are configured for UK VAT and UK carriers — so a British buyer sees familiar options at every step.
