Ecommerce platforms built to sell

Myth Digital is an ecommerce development agency in Belfast and London. Our senior in-house UK team builds stores that are ready to take orders: product catalogues, secure checkout, payment integration and the back-office connections that keep inventory, fulfilment and revenue moving, through a discovery-first process with transparent milestones.

A well-built ecommerce platform does more than display products. It shortens your time to first revenue, converts more browsers into buyers, and removes the manual work that slows fulfilment as order volumes grow.

Talk to us about your store

Most online stores underperform because checkout friction, slow page loads and disconnected back-office systems quietly erode sales. We build stores that tackle those problems head-on. That means faster product pages, streamlined checkout flows, and integrations that connect orders to your inventory and fulfilment without manual re-keying.

The payoff? Higher conversion rates, fewer abandoned carts and a platform that handles demand spikes without falling over. Our senior in-house team pairs UX design with solid engineering so every decision, from catalogue structure to payment flow, is grounded in how real customers actually buy.

Checkout that protects your revenue

Most online shoppers abandon their cart before paying. A complicated checkout, unclear payment options or a missing trust signal is often enough to lose the sale.

We build checkout flows that are performant, clear and compliant with UK Strong Customer Authentication rules. Legitimate buyers aren't blocked and your store meets its obligations. Our UX design process strips friction from every step, while PCI-compliant payment integration keeps card data secure without slowing things down.

  • PCI-compliant payment integration built in
  • UK Strong Customer Authentication handled
  • Fewer steps, lower cart abandonment
  • Trust signals placed where buyers hesitate

Integrations that keep your store running

A store is only as good as the systems behind it. We build the integrations that connect your storefront to the tools your operations depend on.

Which ecommerce platform fits you?

There's no single right platform. The best choice depends on where your business is now and where you want it to go. We start every engagement with a discovery conversation to match the approach to your ambition.

  • Template stores can launch in weeks with lower investment
  • Headless or API-driven builds offer more flexibility over a mid-range timeline
  • A fully custom platform is shaped around your operations and gives ultimate control and potential
  • We help you choose before a line of code is written

How does an ecommerce project work?

Every ecommerce project follows the same milestone-based structure. You see progress, sign off deliverables and stay in control throughout.

  1. Discovery and scoping

    We define success criteria together, map your customer journeys and agree a fixed scope. Nothing gets built until you've signed off the plan.

  2. UX and design

    Our designers produce conversion-focused wireframes and visual designs for every key page, from product listings to checkout. You review and approve each round.

  3. Build and integrate

    Our in-house engineers develop your store and connect payments, inventory and any third-party systems. Each milestone ships a working increment you can test.

  4. Test and optimise

    We run performance, security and checkout testing across devices. Issues get resolved before launch, not after your first customers hit a broken flow.

  5. Launch and handover

    Go-live with our team on hand. We provide training and documentation so your team can manage products, orders and content independently from day one.

  6. Iterate and grow

    Post-launch, we review analytics and run targeted improvements. Conversion tweaks, new features and A/B tests keep your store performing as your business scales.

  • Senior team, no subcontracting

    The people you meet are the people who build your store. Our in-house engineers and designers work together from discovery through to launch, with no offshoring or handoffs to third parties.

  • Discovery before a line of code is written

    Every ecommerce engagement starts with an in-person discovery session at our London or Belfast office. We define scope, success criteria and measurable outcomes before any build work begins.

  • UK-based engineers who understand UK commerce

    Our team works from Shoreditch and Belfast. Our comprehensive knowledge of UK payment regulations, consumer expectations and data-protection requirements is built into every project.

  • Milestone delivery you can track

    We work in phases with clear deliverables at each stage. You see progress, give feedback and sign off before we move on. No big-bang launches, no surprises.

  • Post-launch support that sticks

    Launching your store is the starting line, not the finish. Our team stays with you after go-live to monitor performance, resolve issues and iterate on what the data tells us.

  • Multi-disciplinary by design

    UX designers, software developers and data specialists sit in the same team. Checkout flows, back-end integrations and front-end performance get considered together rather than in silos.

Timelines, investment and what shapes both

Every ecommerce build is different, and honest scoping matters more than a ballpark figure. A template-based store can launch in weeks. A headless or API-driven build typically runs two to four months. Custom platforms with complex integrations and tailored checkout flows can take three to six months or longer.

The variable is scope, not guesswork. Our discovery process fixes requirements, surfaces risks and produces a clear milestone plan before any build work begins. Fewer surprises mid-project. A budget tied to real deliverables, not assumptions.

  • Discovery de-risks scope and cost
  • Template stores launch in weeks
  • Custom builds scoped in milestones
  • No surprises mid-project

How much does ecommerce development cost?

Every store is different. These tiers give you a realistic starting point based on scope and complexity.

  • 4–6 weeks

    Starter Store

    £15,000+

    Your first online store, built on a proven platform with catalogue, cart, checkout and payment integration. Ideal if you're launching ecommerce for the first time.

    • Product catalogue setup
    • Cart and secure checkout
    • Payment gateway integration
    • Mobile-responsive storefront
    • Basic order management
    • Launch support and handover
  • 2–4 months

    Custom Platform

    £40,000+

    A custom or headless build with conversion-optimised UX and integrations to your existing systems. Right for brands that need their store to work harder.

    • Discovery and UX design
    • Custom front-end build
    • ERP, CRM or fulfilment integration
    • Conversion-focused checkout flow
    • Search and filtering
    • Performance and load testing

All builds begin with a paid discovery phase to define scope, success criteria and a fixed-price proposal.

Are we the right fit?

A great fit

  • You need a store that integrates with your existing operations, not just a standalone shopfront
  • You want a senior team building your platform, not freelancers or offshore contractors
  • You value a proper discovery phase that defines scope and success criteria before any code is written
  • You're selling in the UK or EU and need confidence around payments compliance and data protection
  • You want ongoing support after launch, not a handover and goodbye

Not the right fit

  • You need a quick template store with no customisation
  • You're looking for the cheapest possible option above all else
  • You don't have time for a discovery phase and want to skip straight to build
  • You need a simple single-product page with no integrations or checkout logic

FAQ

Ecommerce development FAQs

How long will it take for you to build my app?

That depends on the complexity of the project and whether you are developing hybrid or native. We follow a bespoke software development process that we know takes a minimum amount of time. Depending on your custom requirements, there is no estimate that fits all projects. As a guideline, don’t expect to get an Ionic hybrid app developed in less than 8 weeks, or a React Native hybrid app developed in less than 12 weeks. If you need native, that will be a minimum of 16 weeks per app required.

Can you migrate my store from Shopify or Magento to a custom platform?

Yes. We map your existing product data, customer records, order history and integrations, then rebuild on a platform that fits your growth plans. We run both stores in parallel during the switch so there's no downtime or lost sales.

Which payment providers do you integrate?

We integrate the providers that suit your market and transaction volumes, including Stripe, PayPal and others. Provider fees vary and are set by the provider, not by us. We advise on the best fit during discovery based on your volumes, currencies and customer expectations.

How do you reduce cart abandonment during checkout?

We streamline the checkout flow: fewer form fields, guest checkout options, clear delivery costs shown early, and real-time validation so errors don't force a restart. Our UX designers test each step to remove friction before launch, then we monitor drop-off points post-launch.

Do you build international stores with multi-currency support?

Yes. We build stores that handle multiple currencies, localised tax rules and region-specific payment methods. Product catalogues, shipping logic and checkout can all adapt based on the customer's location, so you can sell across borders from a single platform.

What ongoing support do you offer after launch?

We don't disappear after go-live. Our team provides post-launch support covering bug fixes, performance monitoring and iterative improvements. Because the same people who built the store maintain it, issues get resolved quickly without handover delays.

How do you handle UK and EU payment compliance?

We build to PCI-DSS requirements and implement Strong Customer Authentication so your checkout meets UK and EU regulations. Payment data is handled through certified providers rather than stored on your servers, reducing your compliance burden and protecting your customers.
