Website vs. web application — the actual difference
A business website explains your services and captures leads. A web application has real user logic: accounts, roles and permissions, persistent data and workflows, and actions a user takes inside it, not just reads. If you are unsure which you need, see Website vs Web Application.
How it is built
Which stack fits depends on scope. Our own systems use Next.js and React with PostgreSQL (Clinic Records, Control Center and Logistics OPS); WMS Core runs a separate API with React front ends. Interface-only work is covered in Frontend Application Development and the service layer in API & Backend Development.
Roles and permissions
Login, role-based access and permission boundaries are designed before code is written — see How to Plan Roles and Permissions in a Web Application. Clinic Records, for example, separates each clinic's data with PostgreSQL row-level security.
Integrations and AI
The application connects to your CRM, calendar or messaging tools (see Integrations) and can include AI features — summarisation, classification, a conversational layer — where they solve a real problem inside the product; see How to Add AI Features to an Existing Web Application.
Security and data handling
Access control, data minimisation and a clear answer to "who can see what" are designed in from the start. For the lead-handling side see AI Intake Security & GDPR; a full application with user accounts adds session handling and access logging beyond that page.
What you receive
A working application for the agreed workflows, roles and permissions; the data model and integrations in scope; core user flows tested before launch; deployment to a suitable environment; handover documentation; and the maintenance arrangement agreed for afterwards (backups, dependency updates, monitoring). Scope and price are in writing before work starts, with what is built first and what is left out stated plainly. What moves the price is explained in How Much Does Custom Web Application Development Cost?. If the application already exists, the starting point is an assessment, not a rebuild: see Taking Over an Existing Web App and Changing Software Vendor: Transition Plan.
Why LATYNEX for this
A web application is where design, backend, permissions and deployment decisions depend on each other, so we scope them together instead of as separate hand-offs, and we say so when extending what you already have is the better route than a new build.
Design and engineering are done together, so the interface and what sits behind it are planned as one piece of work rather than handed between vendors.
Work happens inside your real existing systems, repositories and accounts, through access you grant and can withdraw.
Testing, deployment and handover are part of the way we work: checked before release, then documented so someone else can run it. This is a working practice, not a certification.

Mobile — an honest breakdown
We build responsive, mobile-first web applications and PWAs (installable, offline-capable web apps) in-house. We do not have an in-house native iOS/Android or Flutter/React Native team, and we won't claim to. If a project genuinely needs native mobile, we'll say so directly and can bring in a suitable partner for that specific piece rather than overselling capability we don't have. See PWA vs Native Mobile App for a Business MVP for when a PWA is honestly enough.
How it works
- 1
Discovery and product scope
Map who uses the application, what they do and what data has to persist. For an existing application the starting point is an assessment, not a rebuild.
- 2
Roles, data and architecture
Roles and permissions, the data model and the integrations are designed before building starts.
- 3
Build the first release
The agreed workflows are built end to end, not a website with a form bolted on.
- 4
Test against real user flows
The main flows are tested before launch.
- 5
Deploy
Deployment on infrastructure suited to the product's actual traffic and data.
- 6
Maintenance and next steps
An agreed arrangement covers backups, dependency updates and monitoring; further features are scoped separately.

- LATYNEX Digital is a service line of Latynex Trade OÜ, a company registered in Estonia (EU). Contact: info@latynexdigital.com.
- How we work · Delivery
- Remote, in English, with the person who would run the project. No local office is implied in any market.
- How we work · Commercial terms
- One scope and one price, agreed in writing before work starts. Your accounts, code and domain stay yours; any access we use is granted by you and can be withdrawn.
The projects shown above are our own products and sites, not client case studies. Everything else we have built and run ourselves is on the portfolio, each system labelled by stage. Published prices are on the pricing page; anything not listed there is scoped and quoted after review.
Questions
How is this different from Business Website Design?+
A website explains your business and captures leads. A web application has user accounts, roles, persistent data and workflows — genuinely different scope and different pricing logic.
Do you build native mobile apps?+
Not in-house — we build responsive web applications and PWAs, and we're upfront if a project needs a native app, rather than overselling capability we don't have.
Can you add this to an existing product instead of building from scratch?+
Yes — adding a dashboard, a role, an integration or an AI feature to an existing application is common scoped work, not only greenfield builds.
What's the starting point for a first conversation?+
Describe the actual workflow or problem you need the application to handle — that's what determines scope, not a generic package.
Do you have live examples of this specific kind of build?+
We have documented working systems, but they are our own products, not client projects. Clinic Records is a multi-tenant SaaS with roles and an audit log; Control Center is an internal operations platform; Equipment Network is a B2B workspace for lots, buyers and deals; LATYNEX Labs is a public site with an internal publishing back office. The first three are private systems with no public demo, shown with synthetic data; LATYNEX Labs has a public beta site. See selected work for screenshots and what each one does and does not claim.
