Ecommerce development London services from Softomate deliver Shopify Plus custom themes, WooCommerce stores, headless commerce platforms and Magento Adobe Commerce solutions. London retailers managing growing order volumes, multi-channel inventory and complex checkout journeys gain the most value. Stripe, Klarna, PayPal and REST API integrations connect stores with ERP and CRM systems from day one.
Decision framework
UK ecommerce merchants have four main platform routes: a hosted SaaS platform (quickest to launch), an open-source plugin platform built on WordPress (flexible, self-managed), a B2B-focused hosted SaaS platform, or a fully custom Laravel/Node.js build (maximum control, highest cost). A plain comparison for UK businesses:
| Factor | Hosted SaaS | Open-source plugin | B2B-focused SaaS | Custom build |
|---|---|---|---|---|
| Setup cost | £0 + theme/dev | £0 + dev | £0 + dev | £25k-£400k+ |
| Monthly cost | Subscription by plan tier | Hosting £20-£300 | Subscription by plan tier | Hosting £100-£800 |
| Customisation depth | Theme + Apps | Full PHP control | Theme + Apps | Unlimited |
| B2B / multi-currency | Higher plan tiers | Plugin-dependent | Built in | Built to spec |
| UK launch speed | 2-6 weeks | 4-10 weeks | 4-8 weeks | 12-28 weeks |
| Typical fit | £1m-£20m DTC brands | Content + commerce | B2B mid-market | £20m+ or unique workflow |
How we advise: a hosted SaaS platform suits many UK DTC brands under £20m revenue. An open-source platform suits brands where content and commerce blend, such as publishers and blog-heavy brands. A B2B-focused SaaS platform suits many UK B2B mid-market merchants. Custom builds usually make sense above £20m revenue, or when workflow is the differentiator (multi-warehouse routing, complex pricing logic, regulated products). Softomate builds across all 4 routes, and we help you confirm the right one for your revenue, catalogue and integrations rather than defaulting to an expensive custom build.
Ecommerce development London services from Softomate combine Shopify Plus custom themes, WooCommerce bespoke plugins, React and Next.js headless storefronts and Magento Adobe Commerce builds into scalable online selling platforms.

Softomate connects stores with ERP, inventory and CRM systems through REST API and Shopify GraphQL Admin API. Teams wanting a broader digital foundation can combine ecommerce with our web application development services, UX UI design services, API development and system integration services and bespoke software development services.

05. Process
Softomate maps catalogue requirements, selects the right platform, designs checkout journeys and connects payment and inventory integrations in structured delivery phases. Ecommerce managers, IT leads and operations contacts stay involved from discovery through launch, so decisions match conversion, compliance and operational workflow needs.
Catalogue requirements, payment options, inventory integrations and compliance needs are mapped in discovery workshops with ecommerce managers, IT leads and operations contacts. Discovery produces a platform recommendation, integration inventory and PCI DSS compliance scope before project sign-off.
Platform architecture, checkout journey design and UK GDPR data flows are agreed with ecommerce leads, payment and data owners during planning. Planning produces a delivery roadmap, theme specification, API integration map and acceptance criteria covering PCI DSS and compliance requirements.
Storefront designs, product listing layouts and checkout flows are prototyped in Figma with ecommerce managers, brand owners and UX reviewers. Design delivers approved mobile-first layouts, component guides and WCAG 2.1 AA accessibility requirements before theme build begins.
Theme development, payment integration, inventory sync and UK GDPR consent controls are built and tested in delivery sprints with client ecommerce and technology contacts. Build work produces a staging store, tested payment flows, connected REST API integrations and PCI DSS compliance documentation.
Live deployment, payment gateway activation and post-launch monitoring happen after UAT sign-off with ecommerce leads and operations contacts. Launch work produces a live store, monitoring dashboards and a conversion optimisation backlog covering checkout, page speed and payment mix improvements.

09. FAQs
Softomate builds Shopify Plus custom themes and apps, WooCommerce stores with bespoke plugins, headless commerce platforms using React and Next.js, and Magento Adobe Commerce solutions for London retail businesses. Stripe, PayPal and Klarna handle payment processing. REST API integrations connect storefronts with inventory management, ERP and CRM systems. PCI DSS-compliant checkout flows and UK GDPR consent management protect customer data. AWS hosting and CI/CD pipelines ensure reliable deployment. Softomate clients typically reduce manual order processing from four hours per day to under forty minutes after launch. A discovery session defines platform choice, integrations and compliance requirements before any build work starts.
Headless commerce separates the storefront frontend from the ecommerce backend, connecting them through REST API or GraphQL. React and Next.js power the customer-facing experience. Shopify Plus, WooCommerce or a bespoke backend manages products, orders and fulfilment. Headless suits businesses needing custom checkout journeys, fast page loads or content delivery through Contentful. It handles personalisation, A/B testing and multi-channel selling more flexibly than template-based platforms. PCI DSS-compliant payment tokenisation through Stripe or PayPal still applies. Softomate clients using headless typically improve conversion rates by twelve to twenty per cent within sixty days of launch. A discovery session confirms whether headless architecture fits your catalogue, traffic and integration requirements.
Yes. Softomate integrates Shopify Plus with ERP systems, inventory management platforms and warehouse tools through REST API and webhook connections. Product data, stock levels and order status sync in real time without manual exports. Shopify Admin API and GraphQL Admin API handle product, order and customer record updates bidirectionally. OAuth 2.0 secures connections to Salesforce, Microsoft Dynamics 365 and bespoke back-office systems. Softomate clients typically reduce manual stock reconciliation from three hours per day to under twenty minutes after integration. PCI DSS card data never touches your ERP because Stripe handles payment tokenisation before order records reach connected systems. A technical workshop confirms API credentials, webhook events and error-handling rules before build starts.
Softomate ensures PCI DSS compliance by routing all card data through certified payment processors: Stripe, PayPal or Klarna. Card details are tokenised at the browser before transmission, so your server never stores or processes raw card numbers. Shopify Plus and WooCommerce hosted payment pages handle SAQ A scope reduction for most merchants. HTTPS-only delivery, Nginx security headers and AES-256 encryption protect session and personal data. UK GDPR consent capture protects marketing and analytics data separately. Softomate documents the payment data flow, third-party processor agreements and compliance scope during discovery. Merchants processing high volumes receive additional guidance on SAQ A-EP requirements. A compliance review is included before go-live.
Most ecommerce projects for London businesses take six to fourteen weeks from discovery to launch. A focused Shopify Plus theme with standard integrations typically takes six to eight weeks. WooCommerce stores with bespoke plugin development normally take eight to ten weeks. Headless commerce projects with React, Next.js and REST API integration typically take ten to fourteen weeks. Payment gateway configuration, Stripe or Klarna testing and PCI DSS review add one to two weeks. UK GDPR consent flows and cookie management are built in parallel and do not extend timelines significantly. UAT and content migration add five to eight working days. A scoped workshop produces a precise schedule once platform, catalogue size and integration requirements are confirmed.
Yes. Softomate builds WooCommerce stores with Stripe, Klarna and PayPal payment integrations for London businesses. Stripe handles card payments through WooCommerce Stripe Gateway with 3D Secure authentication. Klarna adds buy-now-pay-later options that increase average order value for retail and fashion merchants. PayPal Express Checkout covers wallet payments. WooCommerce REST API connects product catalogues and order data with Salesforce and inventory tools. UK GDPR cookie consent, PECR compliance and Privacy Policy integration are built into checkout flows. Softomate clients typically see a fifteen to twenty per cent increase in checkout completion after Klarna is added alongside Stripe. A discovery session confirms payment mix, product catalogue size and integration scope before build starts.
Standard-platform ecommerce setup starts from £5,000 for a standard Shopify or WooCommerce setup with an agreed catalogue, payments and shipping. Custom ERP integration is quoted separately. Monthly care starts from £199/month. Prices exclude VAT. Required licences, hosting and usage are confirmed separately before you commit.
