Custom Ecommerce Development: Headless, Bespoke Features and Integrations Built for Your Business
Templates stop working when your pricing, catalog or operations are unusual. Our custom ecommerce development covers headless storefronts, bespoke features, pricing and checkout rules, ERP and CRM integration and replatforming. Online stores start from $1,600, and complex builds are priced after discovery.
What custom ecommerce development covers
We build only what the standard platforms cannot do, and we keep the rest standard so the store stays easy to run.
Headless and composable commerce
Custom ecommerce platform design with a custom front end on a commerce back end, for stores that need a unique experience, speed or several storefronts.
Bespoke features and modules
Bespoke ecommerce development of product configurators, subscriptions, bundles, custom checkout steps and rules that no plug-in covers.
Pricing and catalog logic
Customer-specific prices, contract and volume pricing, complex variants and units of measure.
ERP, CRM and POS integration
Ecommerce integration with ERP, CRM, POS, inventory and order management so data flows both ways.
Marketplace and multi-vendor builds
Ecommerce marketplace development as a custom ecommerce website with several sellers, commissions and payouts.
Replatforming and scaling
Ecommerce replatforming, performance work and a scalable architecture for growing traffic and catalogs.
Why merchants choose us for custom ecommerce solutions
Custom ecommerce software development should solve a real problem and be cheap to maintain. We build it that way.
Published starting price
Online stores start from $1,600, and every custom project gets a written scope and a fixed price before work begins.
Standard where possible
We use Shopify, Magento, BigCommerce or WooCommerce for the core and custom code only for what is unique.
Integration-first design
Our custom ecommerce platform work designs the data flow with your ERP and other systems before writing front-end code.
Documented and maintainable
You receive documentation, tests and a clean handover, so another team could take over.
How a custom ecommerce project runs
Discovery
We map business rules, pricing, integrations and what the current platform cannot do.
Architecture and scope
We choose the approach, agree the scope and price in writing and design the data flow.
Build and integrate
We build the custom parts in short iterations, connect the systems and test on real orders.
Launch and improve
We launch in stages, monitor performance and keep improving the store.
When custom development is worth it
Custom work costs more than a template, so it should solve a clear problem.
| Situation | Standard platform | Custom approach |
|---|---|---|
| Complex pricing or contracts | Plug-ins get slow and fragile | Dedicated pricing logic connected to the ERP |
| Unique buying flow | Theme limits the experience | Custom checkout or product configurator |
| Several brands or regions | Many separate stores to maintain | Headless front ends on one back end |
| Heavy integrations | Apps conflict and duplicate data | Direct, tested integrations |
| High traffic and large catalogs | Performance tuning hits a ceiling | Scalable architecture and caching |
In custom ecommerce software development, if a standard platform does the job, we say so, because custom code adds cost and maintenance.
For standard builds on each platform, see ecommerce development services and ecommerce website development.
What good custom ecommerce builds look like in practice
A good custom build starts by asking what the platform already does well. We list the business rules that need custom logic, check whether a configuration or a small module can cover them, and only then design the custom parts. This keeps the store close to a supported platform, so updates and security fixes stay cheap.
People search for this work as custom ecommerce solutions, custom ecommerce software development, a custom ecommerce website, bespoke ecommerce development or headless commerce, and the scope is the same: design the architecture, build the custom parts, integrate and maintain. Technically we work with API-first back ends, headless and PWA front ends, order and inventory management, CRM and ERP integration, POS connections and caching and queues for speed. For omnichannel retail we connect online and in-store data, and for marketplaces we add vendor accounts and payouts.
Costs depend on the amount of custom logic, the integrations and the platform. The cost of a custom build is agreed in writing after a discovery call, and merchants who hire us for custom ecommerce solutions get a scope, a schedule and a fixed price. Online stores start from $1,600 for a standard scope, while complex builds are priced after discovery. After launch we offer ecommerce maintenance and support, so custom modules stay compatible with updates.
Questions we get on the first call
What is custom ecommerce development?
It is building features, integrations or a storefront that standard platforms do not provide, such as headless front ends, special pricing, configurators and ERP-driven data.
How much does a custom ecommerce build cost?
Online stores start from $1,600 for a standard scope. Custom builds depend on the amount of custom logic, integrations and platform, and the price is fixed in writing after discovery.
When should I choose custom over a standard platform?
When pricing, the buying flow, integrations or scale are unusual and plug-ins become slow or fragile. If a standard platform does the job, we recommend it.
What is headless commerce?
It separates the storefront from the commerce back end, so you can build a unique front end and reuse one back end for several storefronts. It costs more to build and maintain.
Can you integrate with our ERP, CRM or POS?
Yes. We design the data flow first, then build and test integrations for stock, prices, orders and customers.
Can you build a marketplace?
Yes. We build multi-vendor marketplaces with seller accounts, commissions and payouts, and we scope them carefully because they are larger projects.
Can you move our store to a new platform?
Yes. We handle replatforming: data mapping, URL redirects, testing and a staged launch, so you keep search positions and sales.
Do you maintain custom code after launch?
Yes. We offer maintenance and support, with documentation and tests, so custom modules stay compatible with platform updates.
