When Do You Need Custom eCommerce?
Custom is the right choice when:
- Complex B2B pricing — customer-specific prices, contract pricing, tiered volume discounts, and negotiated terms that platforms can't model
- Deep ERP integration — real-time inventory across warehouses, order-to-cash automation, and data-layer integration (not just API sync)
- Unique checkout or order logic — configure-to-order, multi-step approval workflows, split shipments, or payment terms that no platform supports
- Multi-tenant commerce — one platform serving multiple brands, markets, or business units with shared infrastructure
- Marketplace — hosting third-party sellers with commission, payout, and catalogue management
- Performance at scale — 100K+ SKUs, high concurrency, and sub-second page loads that platform themes can't deliver
- AI as a core feature — product search, recommendations, and personalisation that need Azure OpenAI integration at the architecture level
A platform is probably better when:
- Standard B2C with a catalogue, cart, and checkout — Shopify launches faster
- Content-led commerce where SEO and blogging matter — WooCommerce on WordPress is stronger
- Speed to market is the priority — platforms are weeks; custom is months
- Your team needs to manage without developers — platform admin tools are easier
We recommend the right path, not custom by default. If Shopify or WooCommerce fits, we will say so. Custom is for cases where the platform would limit pricing, checkout, integration, or operating model.
How We Build Custom Commerce
Free consultation & feasibility
We discuss your commerce model, assess whether custom is warranted (vs platform), and produce a high-level architecture. No cost, no obligation.
Architecture & design sprint
We design the full architecture: data model, pricing engine, API contracts, frontend, checkout, payments, integrations, and hosting.
Core commerce build (sprints)
We build in 2-week sprints: catalogue, cart, checkout, payments, customer accounts, and order management — with demos and feedback.
B2B / marketplace features
We build the specialised features: pricing rules, approval workflows, seller management, subscription logic — the parts that justify custom.
ERP & payment integration
We integrate with ERP, payment processors, shipping, and business systems — real-time, tested, and PCI-compliant.
AI features & search
We implement AI-powered product search, recommendations, and personalisation using Azure OpenAI and AI Search.
Testing, launch & optimisation
We test (functional, performance, security, payment), launch, and optimise based on real user behaviour and conversion data.
It starts with a free consultation. No obligation.

Insights
Custom Commerce Is Differentiation (2026)
In 2026, platforms like Shopify handle many standard e-commerce use cases well. Custom commerce is relevant when the differentiator is the business model itself — complex B2B pricing, deep ERP workflows, marketplace logic, AI-enabled experiences, or multi-tenant architecture that a platform would force into workarounds.

03
Isn't custom e-commerce too expensive?
Custom e-commerce costs more to build than a standard Shopify or WooCommerce site, but it may be the better investment when platform workarounds, transaction costs, integration gaps, or operational constraints become more expensive than owning the commerce logic. If your model is standard B2C, a platform is usually the better choice. If pricing, checkout, ERP workflow, or marketplace logic is central to your business, custom may be justified.
Frequently Asked Questions
What is custom e-commerce development?
Building a bespoke e-commerce application from scratch — product catalogue, pricing engine, cart, checkout, payment processing, customer accounts, and order management — on .NET and Azure, without an off-the-shelf platform like Shopify or WooCommerce.
When does custom e-commerce make sense vs Shopify or WooCommerce?
Custom when: your pricing is complex (B2B, contracts, volume), your checkout or order logic is unique, you need deep ERP integration at the data layer, you’re building a marketplace, or you need multi-tenant commerce. Shopify/WooCommerce when: standard B2C, fast launch, or your requirements fit within platform capabilities. We recommend honestly.
What technologies do you use?
ASP.NET Core and .NET 8+ for backend and API, Blazor or React for frontend, Azure SQL or Cosmos DB for data, Azure App Service or Container Apps for hosting, Azure AI Search + OpenAI for product search, and Stripe or Adyen for payments. Full stack detailed in the Technology Stack section.
Can you build a B2B e-commerce platform with complex pricing?
Yes — complex B2B pricing is the #1 reason organisations choose custom. We build bespoke pricing engines: customer-specific prices, contract terms, tiered volume discounts, regional pricing, and negotiated rates. This is what platforms can’t do well.
How much does custom e-commerce cost?
Custom commerce pricing depends on scope, architecture, and integration complexity. Use $400–$600 per day as the calculator rate. A focused B2C build may require 35–100+ days, while B2B, marketplace, multi-tenant, or composable builds require more effort based on features and integrations. A consultation produces a clearer estimate and fixed scope.
How long does custom e-commerce take?
A focused custom B2C store: 3–5 months. A B2B platform with ERP integration: 4–7 months. A marketplace or composable platform: 6–10 months. We build in 2-week sprints with regular demos.
What is headless commerce?
Decoupled architecture: the frontend (what buyers see) is separate from the commerce backend (products, orders, payments). They communicate via API. Benefits: faster page loads, independent deployment, multiple frontends (web, mobile, kiosk) from one commerce backend.
What is composable commerce?
An architecture where commerce is built from independent, best-of-breed services (catalogue, pricing, cart, checkout, search, payments) connected via APIs — rather than a monolithic application. Maximum flexibility but higher architectural complexity.
