Service line / Websites & Apps
Digital experiences built around the next step.
Design and build websites, applications and stores that make your offer clear and your customer journey easier.

What this practice covers.
Web Design & Development
Most agency websites are designed for how they look in a pitch deck, not for how they perform in Google, in AI answer engines, or in a CRM pipeline report three months later.
Custom Web App Development
Many operational bottlenecks (manual booking management, spreadsheet-based internal tracking, clunky client onboarding) need real software, not another website page or a generic SaaS subscription that almost fits.
UI/UX & Product Design
Products built without proper UX research and a real design system end up inconsistent, confusing for users, and expensive to maintain because every new screen reinvents decisions that should already have been made.
E-commerce Store Build & Optimisation
Most e-commerce builds optimise for how the store looks on launch day and stop there — conversion rate, retention, and AI-driven personalisation are treated as a “phase two” that rarely happens.
From friction to a defined brief
Start with the problem. Build the right response.
A useful engagement connects the business need to concrete deliverables and clear responsibilities.
The goal is clear, but the scope is not.
We map the users, systems and constraints before agreeing deliverables.
The work spans several tools or teams.
We define handoffs, access and approval responsibilities as part of the brief.
A launch alone does not establish success.
We agree acceptance criteria, handover and a method for reviewing what happens next.
Follow the journey from discovery to enquiry.
Content helps a visitor understand the offer. Navigation, page structure and form design work together to make the next action clear.
Navigation and page hierarchy make the relevant service easy to find.
The page answers questions about scope, suitability and evidence.
A clear enquiry journey captures the details needed for a useful reply.
Illustrative delivery model — not a client system or measured performance.
Capability / Build
Web Design & Development
Built for Core Web Vitals, SEO, and GEO from the first wireframe — and wired into your CRM and analytics, not bolted on after launch.
The problem we address
Most agency websites are designed for how they look in a pitch deck, not for how they perform in Google, in AI answer engines, or in a CRM pipeline report three months later.

What is included
- Information architecture and sitemap
- wireframes and visual design
- CMS build (WordPress/ACF as standard)
- on-page SEO and schema setup
- CRM and analytics integration
- performance optimisation to a PageSpeed 90+ target
- launch support
How we approach it
- PageSpeed and Core Web Vitals targets set before design starts, not fixed afterward.
- SEO and GEO structure (schema, llms.txt, AEO-formatted content) built into the template, not added later.
- CMS-driven architecture so the client can edit content without a developer.
From first conversation to handover
- Discovery and sitemap
- Wireframes and design
- CMS build
- SEO/GEO and integrations
- Performance pass
- Launch and handover
Who this is for
Companies replacing a slow, outdated, or unstructured website; businesses about to invest in paid media or content who need a site that converts and reports properly first; anyone for whom the site is part of a wider AI growth stack, not a one-off project.
Before we begin, the proposal confirms the deliverables, dependencies, exclusions and review points. Timing and any ongoing support are agreed for your specific scope.

Custom Web App Development
Client portals, internal tools, booking systems, and dashboards — scoped, built, and shipped with the same discipline as our AI agent builds.
The problem we address
Many operational bottlenecks (manual booking management, spreadsheet-based internal tracking, clunky client onboarding) need real software, not another website page or a generic SaaS subscription that almost fits.
What is included
- Discovery and scoping
- data model and architecture design
- UI/UX design for the application
- full-stack build
- integration with existing systems (CRM, payments, auth)
- QA and testing
- deployment and documentation
How we approach it
- Scoped like software from day one: data model, user roles, and core workflow defined before any design work starts.
- Built to integrate with what already exists (CRM, payment systems, internal tools), not as an isolated silo.
- Shipped with documentation and a handover, whether or not Zinerge continues to maintain it.
From first conversation to handover
- Discovery and scoping workshop
- Architecture and data model
- UI/UX design
- Build (iterative, with milestone reviews)
- Integration and QA
- Deployment and handover documentation
Who this is for
Businesses with a manual, spreadsheet-based, or partially-working internal process that needs real software; companies whose client experience would improve dramatically with a self-serve portal; startups needing a fast, scoped MVP to validate a product idea.
Before we begin, the proposal confirms the deliverables, dependencies, exclusions and review points. Timing and any ongoing support are agreed for your specific scope.

UI/UX & Product Design
User research, wireframes, and a complete UI system — handed to developers in a state that removes ambiguity, not creates it.
The problem we address
Products built without proper UX research and a real design system end up inconsistent, confusing for users, and expensive to maintain because every new screen reinvents decisions that should already have been made.

What is included
- User research and journey mapping
- wireframes and information architecture
- UI design system (components, states, responsive rules)
- high-fidelity screens for core flows
- developer handoff documentation
- one round of usability review post-launch
How we approach it
- Research before pixels — even lightweight user interviews change what gets designed.
- A real design system (components, spacing, states) built once, reused everywhere, not a one-off Figma file per screen.
- Designed in close coordination with whoever is building it — ours, or your own development team.
From first conversation to handover
- User research and journey mapping
- Wireframes and IA
- Build the design system
- High-fidelity screen design
- Developer handoff
- Post-launch usability review
Who this is for
Startups designing a product from scratch; SaaS companies whose product has grown inconsistent over time; teams that have an engineering team but no dedicated product designer.
Before we begin, the proposal confirms the deliverables, dependencies, exclusions and review points. Timing and any ongoing support are agreed for your specific scope.

E-commerce Store Build & Optimisation
Shopify and WooCommerce builds, conversion optimisation, and AI-powered retention loops — measured against revenue per visitor.
The problem we address
Most e-commerce builds optimise for how the store looks on launch day and stop there — conversion rate, retention, and AI-driven personalisation are treated as a “phase two” that rarely happens.
What is included
- Store build on Shopify or WooCommerce
- product page and checkout conversion optimisation
- AI-assisted product copy at scale
- basic retention flows (welcome, abandoned cart, post-purchase)
- analytics and tracking setup
- launch support
How we approach it
- Built on conversion-rate fundamentals from day one: checkout friction, page speed, and trust signals are design requirements, not afterthoughts.
- AI-powered product copy and recommendation logic built into the store, not added as a third-party plugin afterthought.
- Retention (email flows, segmentation, repeat-purchase loops) scoped as part of the build, because acquisition-only e-commerce is the most common reason margins stay thin.
From first conversation to handover
- Platform selection and architecture
- Store build and theming
- Product page and checkout optimisation
- AI-assisted product copy production
- Retention flow setup
- Analytics setup and launch
Who this is for
DTC brands launching their first proper store; businesses migrating from a generic template store to something built for conversion; retailers with high traffic but disappointing conversion or repeat-purchase rates.
Before we begin, the proposal confirms the deliverables, dependencies, exclusions and review points. Timing and any ongoing support are agreed for your specific scope.

Before we begin.
Do we need a finished specification?
No. Start with the business goal, the current process and the main constraint. We can use a focused discovery engagement to turn that starting point into a brief.
Can you work with our existing systems?
We assess available access, integration routes and data quality before recommending changes. A replacement is not assumed.
How are scope and pricing agreed?
Catalogue prices describe starting points. Deliverables, exclusions, third-party fees, tax treatment and payment terms are confirmed in a written proposal before work starts.
What happens after launch?
We agree operational ownership, documentation, training and support needs as part of the engagement. Ongoing work is scoped separately where required.
Ready to define the next step?
Let’s scope websites & apps around your needs.
Tell us the goal and the constraint. We will help shape the right starting point.
