Why choose Unified as your ecommerce development agency
01
We have spent more than 20 years working with ecommerce businesses. Our developers understand the technical challenges behind complex online retail, from product data and international stores to integrations, checkout requirements and high-volume trading.
02
Our ecommerce developers work directly with UX and design specialists. That means creative decisions are grounded in what is technically achievable, performant and maintainable, reducing compromises between initial concepts and the finished website.
03
We work across Shopify Plus, Adobe Commerce, Magento, BigCommerce, Hyvä and headless ecommerce. We recommend and build around the technology that best fits your requirements rather than forcing every brand into the same platform.
04
Your ecommerce website is only one part of your technology stack. We understand how ecommerce platforms connect with ERP, CRM, PIM, OMS, fulfilment, inventory and other systems, helping your wider operation work more effectively.
05
Development decisions affect UX, SEO, conversion, analytics and digital marketing. Our in-house teams work together, helping us identify the wider impact of technical decisions before they become expensive problems.
06
We do not disappear after launch. Many of our client relationships continue through ongoing development retainers, giving brands access to a team that already understands their website, technology and commercial priorities.
Our ecommerce digital marketing process
Discovery
We start by understanding your business, customers, ecommerce platform, technical architecture, internal processes and commercial goals. We identify the requirements, risks and opportunities before development begins.
Strategy
We define the technical approach, platform requirements, integrations and delivery roadmap. Where relevant, our UX, design, SEO and data teams contribute to make sure the wider customer and business requirements are considered.
Design & build
Our designers and ecommerce developers work together to turn requirements into a functional, scalable ecommerce experience. Development is tested throughout the build rather than left until the end.
Test & launch
We carry out quality assurance across devices, browsers, functionality, integrations and performance. Migration projects also include data validation, redirect testing and technical SEO checks before launch.
Improve
After launch, we monitor performance and support continued development. New functionality, optimisation, integrations and technical improvements can be delivered through an ongoing development partnership.
