BigCommerce Development & Strategy
Open SaaS Commerce. Built to Scale.
BigCommerce gives mid-market and enterprise brands the flexibility of open architecture with the reliability of SaaS — and a significantly lower total cost of ownership than legacy platforms. We build, integrate, and optimise BigCommerce stores for ambitious B2B and B2C brands across the UK.
Your Commerce Platform Is Holding You Back
Growing brands on legacy SaaS platforms hit the same walls: limited customisation, rising app costs, and back-end systems that don't talk to each other. BigCommerce solves these structurally — but only when it's implemented correctly.
Runaway Platform Costs
Stacking third-party apps to fill platform gaps inflates your monthly SaaS spend without delivering a proportional return on operational efficiency.
- App subscription costs eroding margin at scale
- Duplicated functionality across overlapping tools
Disconnected Systems
Without clean integration between your storefront, ERP, and CRM, teams resort to manual data entry — creating errors, delays, and a back-office that can't keep pace with order volume.
- Inventory inaccuracies causing fulfilment failures
- No single source of truth across commerce and operations
B2B Buyers on a B2C Checkout
Wholesale buyers expect trade pricing, approval workflows, and account-level purchasing. A consumer checkout loses them at the first hurdle.
- Buyers abandoning due to missing account-based pricing
- Sales teams processing orders manually outside the platform
Storefront Performance Gaps
Default themes and unoptimised builds leave significant conversion performance on the table — particularly on mobile, where most UK shoppers now transact.
- Slow mobile load times suppressing checkout conversion
- Failed Core Web Vitals impacting organic search visibility
BigCommerce Development That Delivers Commercial Results
We treat BigCommerce as a business product, not a build exercise. Every decision — from architecture to integration — is made with your revenue goals, operational model, and growth trajectory in mind.
What We Build on BigCommerce
Store Builds
Custom BigCommerce storefronts built for conversion — mobile-first, performance-optimised, and designed around your buyer's journey from the first interaction to checkout.
Headless & Catalyst Builds
Composable frontends using BigCommerce's Catalyst framework or custom Next.js/React builds — delivering sub-second performance with full API-first flexibility across your commerce stack.
B2B Edition Implementation
Full deployment of BigCommerce B2B Edition — buyer portals, company accounts, price lists, quote workflows, approval routing, and bulk ordering — purpose-built for UK wholesalers, manufacturers, and distributors.
ERP & Systems Integration
Bi-directional integrations between BigCommerce and your ERP, OMS, CRM, and PIM — eliminating manual sync and giving every team real-time visibility across commerce and operations.
Platform Migrations
Structured replatforming from Magento, WooCommerce, Shopify, or any legacy system to BigCommerce — with full data migration, SEO continuity, and zero disruption to live trading.
Optimisation & Managed Support
Ongoing CRO, performance audits, feature development, and SLA-backed managed support — keeping your BigCommerce store fast, secure, and continuously improving post-launch.
A UK Wholesale Brand's Journey to Self-Service Commerce
Discovery & Scoping
A UK-based manufacturer is processing wholesale orders via email and phone. We audit their current setup, map their buyer journey, and define the full BigCommerce B2B architecture.
B2B Edition Build
We implement BigCommerce B2B Edition with a branded buyer portal, company accounts, customer-specific price lists, and a quote-to-order workflow — live in eight weeks.
ERP Integration
BigCommerce connects bi-directionally to their ERP. Inventory, pricing, and order data sync in real time, eliminating manual reconciliation across their wholesale operation entirely.
Growth & Optimisation
Post-launch CRO sprints, performance monitoring, and ongoing feature development compound improvements quarter over quarter — turning the store into a self-sustaining revenue channel.

What Makes Our BigCommerce Practice Different
Certified BigCommerce Expertise
Our developers and strategists hold active BigCommerce certifications — covering B2B Edition, headless architecture, and enterprise implementations — not just theme-level familiarity with the platform.
Commerce-First Thinking
We start with your commercial model and buyer journey, then select the right technical approach. A technically impressive build that doesn't convert is not a successful project.
B2B Specialists
BigCommerce B2B Edition is one of the strongest wholesale platforms available today. We've implemented it for UK manufacturers, distributors, and hybrid B2B/B2C brands across multiple verticals.
Deep Integration Experience
From NetSuite and SAP to Salesforce and Dynamics 365, we've built and maintained enterprise integrations at scale — in live production environments where reliability is non-negotiable.
Long-Term Partnership Model
We don't build and hand over. Our retainer model keeps a dedicated team active on your account — continuously improving performance, not just maintaining the status quo.
