Commerce for catalogues that break the rules.
Configurable products, contract pricing, multi-warehouse stock and approval workflows — built when a hosted platform cannot express how you actually sell.
- B2B pricing
- Complex catalogues
- ERP integration
Bespoke commerce platforms for catalogues, pricing and fulfilment rules that need custom logic.
When the cart is the hard part.
B2B and specialist retail rarely fit a standard cart: customer-specific price lists, quantity breaks, quotes, credit terms and split fulfilment all collide.
Why it matters
Some catalogues, pricing rules or fulfilment models simply do not fit a hosted platform. A custom storefront removes those constraints, with ownership of the whole funnel.
What we build
Bespoke storefronts and checkouts, complex pricing and configurators, B2B portals, ERP and inventory integration, and headless commerce backends.
Who it is for
B2B sellers with contract pricing, brands with configurable products, marketplaces, and retailers with deep ERP integration needs.
What we handle from strategy to delivery.
Six areas we take responsibility for on custom e-commerce engagements — no handoff gaps between them.
- 01
Commerce discovery
Catalogue, pricing rules, tax, shipping and fulfilment realities.
- 02
Storefront experience
Search, filtering, product pages and cart designed to convert.
- 03
Custom checkout
Multi-step, saved carts, quotes and account-based purchasing.
- 04
Pricing & promotions
Tiered, contract and volume pricing with rules engines.
- 05
ERP & inventory integration
Stock, orders, invoices and fulfilment kept in sync.
- 06
Scale & reliability
Caching, load testing and monitoring for peak trading.
Standards we hold every custom e-commerce project to.
- Full control
- Own the checkout funnel
- Complex pricing
- Contract and tiered rules
- ERP connected
- Live stock and orders
- Peak ready
- Load tested for campaigns
From first conversation to a product that is ready to grow.
01 — Discover
We review the catalogue, pricing rules, fulfilment and the drop-off points in the current funnel.
We review requirements, existing analytics, competitors and user needs to understand where custom e-commerce will create the most value. Nothing is proposed before the problem is clear.
Deliverables
- Commerce requirements
- Catalogue assessment
- Conversion baseline
Typical activities
- Stakeholder workshop
- Analytics review
- Competitor teardown
Success criteria
A clear, shared understanding of the problem, scope and expected outcome.
02 — Define
We agree the platform approach, data model and integrations before design begins.
We turn research into a clear product direction, priorities and information architecture. Scope, sequencing and technical direction are agreed in writing before work starts.
Deliverables
- Platform decision
- Product data model
- Integration plan
Typical activities
- Technical design
- Migration planning
- Estimation
Success criteria
Everyone understands what is being built, in what order, and why.
03 — Design
We design browsing, product and checkout experiences around conversion on mobile first.
We translate the agreed structure into a polished, responsive interface — every state, breakpoint and edge case included, reviewed together as we go.
Deliverables
- Storefront designs
- Checkout flow
- Merchandising sections
Typical activities
- Flow design
- Visual design
- Review
Success criteria
The experience is validated and ready for implementation.
04 — Build
We implement the storefront, checkout and integrations with stock, payments and fulfilment.
We turn approved designs into production-ready software using maintainable components and a scalable architecture. You see working software throughout, not just at the end.
Deliverables
- Storefront implementation
- Payment integration
- ERP or inventory sync
Typical activities
- Development
- Integration work
- Code review
Success criteria
The product works reliably across the required devices and scenarios.
05 — Validate
We test the full purchase path, including refunds, edge cases and peak-load behaviour.
We test the product against the real requirements, profile performance and surface issues before launch rather than after it.
Deliverables
- Checkout test matrix
- Performance results
- Migration dry run
Typical activities
- Transaction testing
- Load testing
- Redirect verification
Success criteria
Critical issues are resolved and the product is ready for launch.
06 — Launch
We go live with redirects, analytics and a plan for post-launch conversion improvements.
We deploy, review the built product in production and refine the details that only appear in the real thing. Monitoring and handover happen at the same time.
Deliverables
- Live store
- Redirects and analytics
- Optimisation backlog
Typical activities
- Cutover support
- Monitoring
- Conversion iteration
Success criteria
The product is live, verified, documented and ready for users.
Everything handed over, nothing locked away.
Concrete output at the end of a custom e-commerce engagement — code, assets and documentation you own.
The stack we reach for first.

Questions we get asked.
Still unsure about something on custom e-commerce? Ask us directly — we answer honestly, even when the answer is no.
Usually you should. Custom commerce is for catalogue, pricing or fulfilment rules the platform genuinely cannot express.
Yes, with separate pricing, tax and checkout behaviour per customer segment.
Card data goes directly to the payment provider; we never store it, which keeps your scope minimal.
When pricing logic, B2B workflows, catalogue complexity or integrations exceed what the platform allows.
Payments go through certified providers with hosted fields, so card data never touches your servers.
Yes — stock, pricing, orders and invoices, with retries and reconciliation.
Yes, with a mapped data migration, redirect plan and phased cutover.
