Overview
Custom Web Development at 24Square Technologies
Custom web development means building a website or web application around how your business actually works, rather than fitting the business around a purchased template. It suits organisations whose site has to do a job — generate qualified enquiries, run a booking or quoting journey, or give staff a tool they use daily. We handle frontend and backend development, APIs, integrations, performance and accessibility as one piece of work.
Every project starts with the outcome you need. From there we plan structure, design and technology together so nothing is bolted on later, and we build in reviewable stages with code and documentation you own.
Where your team needs to publish and edit content without developer help, we pair the build with CMS development so pages are made of structured, reusable blocks rather than free-form page-builder layouts.
If the site also needs to sell, the same foundations extend into eCommerce development, covering catalogue structure, checkout and payment gateway integration alongside the marketing pages.
For a new product rather than a new website, it is often better to start smaller with MVP development and prove the core journey before committing to a full platform build.
Problems this service solves
- An outdated site that no longer reflects how the business works today
- Slow pages and poor Core Web Vitals hurting search visibility
- Content that only developers can update
- Layouts that break on tablets and phones
- Enquiry forms that lose leads or attract spam
Capabilities
Key capabilities and deliverables
What is included when you engage us for this service.
Custom website design and build
Bespoke layouts and components designed around your content, not a purchased theme.
Web application development
Dashboards, portals and internal tools with authentication, roles and reporting.
Performance engineering
Image optimisation, code splitting and caching to keep pages fast under real conditions.

Analytics and tracking setup
Event tracking on the actions that matter so you can measure what the site produces.
Capability
API Development & Integrations
Most web projects need to exchange data with something else. We design APIs and integrations that other teams can actually use: predictable endpoints, versioning, authentication, sensible errors and documentation that stays current.
- Custom REST API development with versioning and rate limiting
- Third-party API integrations across the tools you already use
- Payment gateway integrations for checkout and billing
- CRM integrations that keep sales and marketing data in step
- SaaS integrations for accounting, logistics, support and ERP
- Internal system integrations replacing manual exports
- Webhooks and event-driven updates between systems
- Data synchronisation with clear conflict and retry handling
- Secure API architecture with scoped permissions, validation and logging

- How long does a website project take?
- A focused marketing site typically runs four to eight weeks, while a larger web application depends on scope. We confirm a milestone plan before development starts.

- Yes. We review the current site, keep what already works, migrate content and improve structure, speed and conversion paths.
- Will we be able to update content ourselves?
- Where you need editable content we connect a CMS with clearly defined fields, so your team can publish without touching code.
- Do you build APIs and integrations as part of a web project?
- Yes. We build custom REST APIs and connect payment gateways, CRM, ERP and other SaaS platforms, including webhooks and scheduled data synchronisation.
- Do you handle hosting and deployment?
