What is Custom E-Commerce Development?

Custom e-commerce development means building your online store from the ground up rather than adapting a template platform like Shopify or WooCommerce. The decision to go custom is usually driven by catalogue complexity, unique checkout logic, or a need for performance and ownership that template platforms cannot deliver at scale.

Headless commerce is a subset of custom development where the frontend and backend are decoupled. Your storefront is a fast, custom-built React or Next.js application that communicates with a commerce API. This gives you full design freedom, near-instant page loads, and the ability to serve commerce across web, mobile apps, and in-store kiosks from a single backend.

A full custom e-commerce build covers the storefront, product catalogue and search, checkout and payment processing, order management system, customer accounts, and third-party integrations with logistics, ERP, and marketing tools. You own the code, the data, and the roadmap.

Our Services

E-Commerce Development Services

End-to-end commerce engineering from storefront to fulfilment.

01

Custom Storefront Development

Bespoke frontend, product pages, collection pages, search, and filters built for conversion. Every interaction is designed around your catalogue structure and customer journey, not a generic theme.

02

Headless Commerce Architecture

Decoupled frontend and backend for performance and flexibility across web, mobile, and kiosks. Your commerce engine powers every surface without the constraints of a monolithic platform.

03

Marketplace Platform Development

Multi-vendor marketplace with seller onboarding, commission management, payout, and reviews. We build the full operator and seller tooling so you can launch and grow a two-sided commerce platform.

04

Storefront Performance That Drives Revenue

Every 100ms of page load time costs measurable revenue. Generic templates are built for the average merchant, which means the checkout flow, product page layout, and navigation are all compromises. A custom storefront built to your catalogue and customer behaviour can lift conversion rate by 20 to 40 percent compared with a template baseline.

We set Core Web Vitals targets at the start of every project and build the architecture to hit them. CDN configuration, image optimisation, lazy loading, and edge caching are engineering requirements, not afterthoughts. The result is a storefront that ranks better, loads faster, and converts more of the traffic you already have.

Our Process

From Requirements to Revenue

A structured delivery process that eliminates surprises and keeps go-live on schedule.

01

Commerce Requirements Mapping

Catalogue structure, checkout flow, fulfilment model, and integration list documented before a line of code is written.

02

UX and Conversion Design

Wireframes and prototypes tested for checkout completion rate. Every screen is validated against your conversion goals before build starts.

03

Storefront Development

Frontend built for performance with Core Web Vitals targets set at kickoff. Product pages, collection pages, search, and checkout engineered to convert.

04

Commerce Engine and OMS

Product catalogue, pricing rules, orders, and fulfilment logic built to your business model. Custom OMS if your fulfilment complexity requires it.

05

Payment and Integration Layer

Payment gateways, logistics APIs, and ERP/WMS connections tested in staging before go-live. Tax and fraud rules configured per market.

06

Launch and CRO

Go-live, performance benchmarking, and conversion rate baseline established. Analytics and A/B testing infrastructure ready from day one.

Indicative Pricing

E-Commerce Development Investment

Scope-based pricing that reflects build complexity, not arbitrary day rates.

Project TypeScopeIndicative Cost
Custom storefront (Shopify/headless)Up to 500 SKUs, standard checkout$20,000 - $50,000
Full custom e-commerce platformCustom OMS, multi-currency, integrations$60,000 - $150,000
Marketplace platformMulti-vendor, seller portal, payout$100,000 - $250,000+

Indicative ranges. Exact pricing depends on catalogue size, integration complexity, and OMS requirements. We provide a detailed breakdown after a scoping call.

Why CodeShiper

What Makes Our E-Commerce Builds Different

Six principles that change the outcome of a commerce project.

01

Conversion-First Design

Every UI decision is tested against checkout completion and revenue per visitor. We do not ship screens that look good but do not convert.

02

Performance Engineering

Core Web Vitals targets are set before the build starts, not bolted on after. Performance is a design constraint, not an optimisation task.

03

Commerce Domain Depth

We understand catalogues, pricing rules, fulfilment, and returns at code level. This means fewer edge cases discovered in production.

04

Payment Integration Expertise

Stripe, PayPal, BNPL, multi-currency, and tax handled without surprises. We have solved the hard currency and compliance edge cases before.

05

Scalable Architecture

Built to handle traffic spikes during launches and sales events without downtime. Load tested before go-live so you are not discovering limits in peak season.

06

Post-Launch CRO Support

A/B testing infrastructure and analytics built in so you can keep improving. We offer retainer-based CRO support after launch for teams who want to keep optimising.

FAQ

Common Questions About E-Commerce Development

When should I build a custom e-commerce store instead of using Shopify?
A custom build makes sense when your catalogue, pricing rules, or checkout flow cannot be expressed in a template platform without heavy workarounds. Common triggers are complex product configurators, B2B pricing tiers, custom fulfilment logic, or a need to own the full data model for analytics and personalisation. If your annual GMV is above $2M or you are experiencing platform limitations that cost you conversion, a custom build typically pays back within 18 months.
What is headless commerce and do I need it?
Headless commerce separates the frontend presentation layer from the backend commerce engine. Your storefront is a custom React or Next.js application that fetches data from a commerce API - giving you full control over performance, UX, and design without being constrained by a theme system. You need it when page speed is a conversion priority, when you are delivering commerce across multiple surfaces (web, mobile app, kiosk), or when your marketing team needs to move faster than a monolithic platform allows.
How much does custom e-commerce development cost?
A custom storefront built on a headless commerce platform for up to 500 SKUs typically costs $20,000 to $50,000. A fully custom platform with a bespoke OMS, multi-currency support, and third-party integrations runs $60,000 to $150,000. A multi-vendor marketplace with seller onboarding, commission management, and payout infrastructure starts at $100,000 and can reach $250,000 or more depending on complexity. We provide a detailed breakdown after a scoping call.
How long does it take to build a custom e-commerce platform?
A custom storefront for an existing catalogue takes 10 to 16 weeks from kickoff to go-live. A full platform with custom OMS and integrations is typically 20 to 32 weeks. Marketplace builds are 24 to 40 weeks depending on seller tooling complexity. These timelines assume a clear scope, available stakeholders for sign-off, and content ready for migration. We provide a milestone-based schedule at the start of every engagement.
Can you migrate our existing store and product data?
Yes. We handle data migration from Shopify, WooCommerce, Magento, BigCommerce, and custom platforms. This includes product catalogue, variant data, customer records, order history, and URL structure for SEO continuity. We run a parallel environment and validate data integrity before cutover. SEO redirects are mapped and deployed on launch day to protect your organic rankings.
Which payment gateways do you integrate with?
We integrate with Stripe, PayPal, Braintree, Adyen, Klarna, Afterpay, and regional gateways including Razorpay and Mollie. We also handle Apple Pay, Google Pay, and Buy Now Pay Later options. Tax calculation via TaxJar or Avalara is included in all payment integration work. If you have an existing payment provider relationship, we will integrate with their API regardless of platform.
Can you build a multi-vendor marketplace?
Yes. We build marketplace platforms with seller onboarding flows, individual seller storefronts, product listing management, commission configuration, automated payout via Stripe Connect, and buyer and seller review systems. We also build admin tooling for marketplace operators to manage disputes, commission tiers, and seller performance. Marketplace builds are scoped individually based on category complexity and seller tooling requirements.
How do you handle inventory sync across multiple channels?
We build a centralised inventory service that maintains a single source of truth and syncs to all sales channels in real time. This covers your web storefront, mobile app, point of sale, and any third-party marketplaces like Amazon or eBay. We integrate with warehouse management systems and 3PL providers via their APIs. Oversell protection and low-stock alerting are standard features of every inventory integration we build.
What happens to our store's SEO during and after migration?
We audit your existing URL structure before migration and build a redirect map that preserves all ranking URLs. We implement canonical tags, structured data for products and breadcrumbs, sitemap generation, and Core Web Vitals targets as part of the build. After launch we provide a 30-day monitoring period to catch any ranking fluctuations and address them. SEO is treated as a first-class requirement in every e-commerce project, not an afterthought.
Do you provide support after the store launches?
Yes. We offer retainer-based support covering bug fixes, performance monitoring, A/B test implementation, and feature development. We also provide a 90-day warranty period after launch that covers defects at no extra cost. For high-GMV stores we offer an SLA-backed support tier with guaranteed response times and a dedicated point of contact. Support scope and pricing are agreed at project kickoff.
