Web development

Websites and web apps that take orders, bookings and data

ExtraDigital builds websites and web applications for organisations whose site has real work to do: taking orders, capturing qualified enquiries, handling bookings or connecting to internal systems. Development is delivered in-house in the UK, to ISO 9001 processes, with SEO, conversion and tracking considered from the first technical decision.

  • Bespoke database‑driven development
  • Payment gateways, bookings, registrations and stock APIs
  • Multilingual builds in 15+ languages
  • ISO 9001 certified delivery and QA

Built to do real work

What we develop

  • Corporate and content‑managed websites
  • Lead generation platforms
  • Ecommerce stores
  • Booking and registration systems
  • Customer portals
  • Bespoke database applications

We also handle the unglamorous work that keeps sites alive: platform upgrades, security patching, performance tuning, accessibility improvements and rescuing projects that have been left unmaintained.

Where a content management system is the right answer we use one. Where it would force awkward compromises, we build what the requirement actually needs.

Good to know

Frequently asked questions

Is development done in-house?

Yes. Our developers are part of our UK team and work directly with the designers and marketers on your project.

Which technologies do you work with?

WordPress, Shopify, WooCommerce and CS-Cart, plus bespoke database-driven development where an off-the-shelf platform will not do the job.

Can you integrate our existing systems?

We regularly integrate payment gateways, booking and registration systems, stock and product feeds, CRM platforms and internal business systems.

Can you take over a site built by another agency?

Usually. We review the codebase, hosting and platform version first, then tell you honestly whether it is better to maintain, improve or replace it.

How do you manage quality and timescales?

We are ISO 9001 certified, with documented planning, delivery management and QA processes, plus agreed milestones so you can see progress.
