Our services

Our Range Of Custom eCommerce Development Services

From custom eCommerce stores and marketplace development to migrations, performance optimization, and feature enhancements, we build scalable eCommerce solutions tailored to your business. Every project is designed to deliver exceptional user experiences, seamless functionality, and long term growth.

eCommerce Strategy & Consultation

We map your catalogue, checkout rules, integrations and hosting before anything is designed, then recommend the shortest path to launch.

Custom eCommerce Design

UI and UX for every template you will actually use, designed mobile first and signed off in Figma before a single line of code is written for creating your store for better design.

Custom eCommerce Development

From eCommerce stores and custom plugins written to WordPress coding standards, so your functionality survives theme changes and core updates.

eCommerce Platform Migration

Shopify, Magento or legacy builds moved to WooCommerce or any other CMS with products, customers, orders and URL structure intact, and a redirect map written first.

ERP & CRM Integration

Inventory, orders and customer records synced both ways through documented, testable API layers with retry handling, all things done perfectly.

Support & Maintenance

Updates tested on staging before production, backups, uptime monitoring and a named developer who answers your email directly.

B2B & Wholesale Pricing

Role based price tiers, minimum order quantities, quote requests and customer specific catalogues.

Store Speed Optimization

Plugin audit, slow query profiling, asset and caching strategy. You get before and after Core Web Vitals from field data, not a synthetic score.

Multi-Currency Checkout

Geo aware pricing, currency switching and local payment methods so international customers see prices they understand.

Included

What Every Store We Build Comes With

Full code ownership

Everything we write for you transfers to you at handover, with documentation your next developer can read.

Staging environment throughout

You can open the build any time. Nothing reaches your live store without being tested first.

Core Web Vitals pass on mobile

Speed is designed in from the first template, not bolted on with a caching plugin or addons at the end.

30 days of post launch support

Included with every build, plus admin training so your team can run the store without calling us.

FAQ

Frequently Asked Questions

How much does custom eCommerce development cost?

Most store builds land between $500 and $15,000 depending on catalogue size, checkout complexity and how many systems need to connect. We send a fixed estimate after scoping, and it does not change unless you change the scope.

How long does a project take?

A standard store build runs four to eight weeks. Migrations take three to six weeks depending on data quality. Plugin work can be as short as one week. You get a stage by stage timeline with your estimate.

Which platform will you build my store on?

Whichever one fits your catalogue, budget and team. We recommend a platform during scoping and explain the trade-offs in plain language, including running costs and how easy it will be to hire for later. If you already run something, we work with it.

Who owns the code you write?

You do. Custom code written for your project transfers with the project along with documentation. Third party licensed products keep their own licence terms, which we list in the scope.

Can you take over a store another agency built?

Yes. We start with a paid audit of the existing code, plugin stack and hosting so you know the condition of the store before committing to a larger scope. You keep the audit document either way.
