Website & Web Application Development

Corporate website, ecommerce and custom web application development with a CMS, search-ready structure and CRM integrations.

Website & Web Application Development

Turn first impressions into a clear next step.

Business website development starts with the visitor’s task: choosing a service, buying a product or using a customer portal. We build corporate websites, ecommerce stores and custom web applications around those journeys. Scope includes agreed design, content responsibilities and integrations, with CMS access and team instructions at handover.

  • A clear customer journey

    Each page answers a visitor question and offers a relevant next step.

  • Content you control

    Update copy, services and case studies through a practical administrative interface.

  • Room to evolve

    The architecture anticipates the sections, languages and integrations your business needs next.

What you get

What we deliver

Structure and prototype

Map the audience and pages, then validate the main journeys before visual design.

A distinctive interface

Create a visual system, responsive layouts and complete states for forms, menus and interactive elements.

Engineering and integrations

Build the interface, CMS, forms, portals and agreed connections to your business systems.

Validation and handover

Check core devices and journeys, prepare editor instructions and agree the launch plan.

A polished interface should also be practical

We consider more than the homepage: finding information, mobile navigation, form errors and editorial workflows all matter. These details shape the company’s first impression and the team’s everyday experience.

Choose a product around the job it needs to do

Business and service websites

Help visitors compare offers, understand terms and send an enquiry. Plan language versions, service pages, portfolio content and editing workflows around your actual materials.

Ecommerce websites

Scope the catalogue, search, filters, basket, payment and fulfilment. Stock handling, product variants and integrations need their own requirements: page count alone does not describe complexity.

Customer portals and web applications

Define roles, data and workflows for orders, documents, approvals or self-service. Start with a testable first release. A native mobile application is a separate scope if your project needs one.

Development deliverables from brief to handover

Prototype and specification

Receive a page map, core journeys, clickable prototype and acceptance criteria. Agree who supplies copy, translations and imagery before missing materials become a launch dependency.

Design, CMS and integrations

Responsive layouts include loading and error states, editable sections, forms and agreed connections. Technology choices follow maintainability, integration and budget requirements, with third-party costs made explicit.

Release and ownership

Verify agreed devices and journeys, document deployment and train editors. A replacement website includes a URL migration map and rollback plan. Ongoing support has its own agreed scope.

Example website acceptance criteria

Illustrative scenarios for a specification, not client project results. Supported browsers, constraints and expected outcomes are agreed before implementation.

Website development cost and delivery schedule

Estimates account for page types, journeys, permissions, languages, integrations and data migration. Separate the first release from later phases, and development from content, hosting, licences and maintenance. Requests beyond the approved scope receive a new estimate.

Timing depends on access, materials and review turnaround. Working versions are reviewed during delivery rather than only at launch. Share your current website, essential functions and the main action a visitor should complete to start the estimate.

Quality you can verify before launch

Check mobile journeys, keyboard navigation, field labels, contrast and understandable error messages. Agree accessibility requirements and manual checks explicitly: an automated score does not establish full WCAG conformance.

The technical SEO baseline covers agreed metadata, indexability, canonicals, language links and sitemaps. Measure speed under defined conditions and conversions through agreed analytics. Release readiness and commercial growth require different evidence and observation periods.

From brief to launch

A clear path to launch

  1. Define the brief

    Agree the audience, objectives and first-release scope.

  2. Make the solution visible

    Review prototypes and design against real user journeys.

  3. Build the product

    Deliver in stages with reviewable working versions.

  4. Launch and hand over

    Verify forms, measurement and content, then train the editors.

Before we start

Good questions before we start

Can we improve an existing site?

Yes. After reviewing the code and goals, we can improve the current system, rebuild specific sections or replace outdated parts in stages.

Who will update copy and images?

Your editor can work through the CMS. We agree which sections must be editable and demonstrate that workflow before handover.

How do you estimate the project?

The estimate follows page scope, user journeys, integrations and content requirements. The brief separates the essential first release from later improvements.

Does website development include content and translations?

The proposal identifies client-supplied materials and any commissioned content. Agree image rights and who verifies business claims and specialist facts.

Who owns the code, domain and accounts?

The contract defines rights and handover. Plan for client-controlled repositories, domains and accounts; third-party components retain their own licences.

Can we start with an MVP?

Yes. Prioritise one core journey and its necessary roles and integrations, with later work in a separate backlog. An MVP still needs quality and acceptance criteria.

How do you migrate an existing website?

Inventory important URLs, content and metadata. Agree redirects, verify language versions and monitor release errors. Unchanged search traffic cannot be guaranteed.

Is ongoing SEO included?

Technical preparation is specified in the development scope. Ongoing search strategy, new editorial content and external publications are separate services.

How are payments and external APIs tested?

Use a sandbox where the provider supports one. Check success, rejection, repeated events and connectivity failures; production cutover requires an agreed plan.

What happens after launch?

Receive instructions and an account inventory. Defect resolution, support hours and new functionality have separate terms; unlimited maintenance is not assumed.

AVIAL SERVICE

What should your website make possible?

Share your current website or the idea behind the next one. We will help define the first release and design direction.

Avial Service

Request an estimate for website or app development

Describe your goal and current setup. We will clarify scope, costs and a first phase. An enquiry does not commit you to a purchase.

Your contact email and phone are required for estimates and requests.

Details for an estimateOptional

Add a project link if available, budget and preferred timing. Do not include passwords or confidential data.

Tools for your project
