An Online Store That Doesn't Just Exist, It Sells

Most e-commerce stores lose customers at the same predictable points: slow load times, confusing navigation, clunky checkouts, and mobile experiences that feel like an afterthought. We build ecommerce solutions that remove every one of those barriers.
From brand-new stores to complex platform migrations, CentNine delivers end-to-end ecommerce development services — design, build, payment integrations, and post-launch optimisation. Your store, working at its full potential.

Everything Your E-Commerce Store Needs

End-to-end ecommerce services — from first click to completed checkout.

Store Design & UX

Custom-designed store experiences built for conversion — clear product pages, intuitive navigation, trust-building layout, and mobile-first design that makes buying easy on any device.

E-Commerce Development

Full ecommerce development services across all major platforms. New store builds, redesigns, feature additions, and custom development — all to spec and on schedule.

Payment Solutions

Ecommerce payment solutions including Stripe, PayPal, Apple Pay, Google Pay, Klarna, and regional gateways. We handle the integration so checkout is fast, secure, and frictionless.

Platform Migration

Moving from Magento to Shopify? WooCommerce to a custom build? We handle migrations without losing your data, your SEO rankings, or your customer history.

Product Catalogue Setup

For stores with large product catalogues — bulk product import, variant setup, category architecture, and metadata optimisation for search visibility and ecommerce SEO.

App & Tool Integrations

Connecting your store to the tools you need — email marketing, CRM, inventory management, loyalty programmes, reviews platforms, shipping providers, and more.

Speed & Performance Optimisation

A 1-second delay in load time reduces conversions by 7%. We optimise your store's speed, image handling, and Core Web Vitals so you never lose a sale to a slow page.

Platforms We Work With

We don't push one platform over another — we recommend based on your business size, budget, product complexity, and growth plans.

Shopify
Most Popular

Best for most growing e-commerce brands. Fast to launch, easy to manage, vast app ecosystem.

WooCommerce
For WordPress

Best for WordPress users who want flexibility and control without platform fees.

Magento
Enterprise

Best for large catalogues and enterprise-level customisation requirements.

BigCommerce
B2B & Multi-Channel

Strong for B2B e-commerce and multi-channel selling across multiple storefronts.

Custom Builds
Bespoke

When off-the-shelf platforms aren't enough for your specific requirements — we build from the ground up.

Conversion Rate Optimisation

We Build Stores That Sell,
Not Just Stores That Look Good

Beautiful e-commerce design is table stakes. What separates a 1% converting store from a 4% converting store is the detail — the placement of trust signals, the friction in the checkout, the copy on the product page, the upsell timing.

Every store we build includes CRO principles from day one:

  • Product pages designed to handle objections and build confidence
  • Checkout optimised for minimum drop-off — guest checkout, progress indicators, saved cards
  • Trust elements placed where doubt happens — near CTAs, in cart, at payment
  • Upsell and cross-sell logic built into the cart and post-purchase flow
  • Mobile checkout treated as the primary experience, not a secondary one

Frequently Asked Questions

For most new stores, Shopify is our default recommendation. It's fast to launch, easy to manage without technical knowledge, has excellent app support, and handles everything from small stores to high-volume operations. That said, WooCommerce is better if you're already on WordPress and want maximum flexibility, and custom builds are right when your requirements go beyond what platforms offer out of the box.
We integrate all major payment providers — Stripe, PayPal, Apple Pay, Google Pay, Klarna (buy now pay later), Afterpay, and regional gateways depending on your target markets. Multi-currency and multi-payment setups are also something we handle regularly.
A standard Shopify or WooCommerce store typically takes 5–8 weeks. More complex builds with large catalogues, custom functionality, or integrations take 8–14 weeks. We give you a specific timeline with the project proposal.
Yes — platform migration is one of our ecommerce services. We migrate your products, customer data, order history, and existing content, and we handle the SEO redirect mapping so you don't lose your organic rankings in the process.
We do both, and this is genuinely one of our biggest advantages. Many agencies build stores then leave you to figure out traffic. We offer performance marketing, SEO, email marketing, and CRO as integrated services — so the store we build is designed to work with the traffic strategy we run.
Custom features are our specialty within ecommerce development services — whether it's a custom product configurator, subscription logic, loyalty programme, B2B pricing tiers, or API integration with your inventory system. We scope and build custom functionality as part of the project.
